shimocha was pretty much certainly tenpai. I thought it best to defend since I wasn't last + this isn't a winner hand + if I deal in, then I might instantly lose. the safest tiles are: 1m and 5p. souzu is all unsafe as shimocha might have honitsu. all in all, looking at shimocha only, 1m is the safest, but if I had considered that kamicha was pushing, I should've went for 5p5p.

Would you ron here? I did because 4th is closer than 2nd and 1st, but I could've tsumoed 8m later if I chose to hang on, and then I would've had a realistic chance of getting first.

>>21287781
several books have info on this. 科学する麻雀 has a big table that has the probability of someone being in tenpai based on how many calls they made + what turn it is. 絶対にラスを引かない麻雀 also has info on basic yomi in it. デジタルに読む麻雀 from the same author is one of the standard books on yomi, I've only ever seen praise for it. it probably has everything in it, but I can't tell you as I haven't read it yet (even though I already have it sitting in my room).

hand value: an average ko riichi is 6000, an average oyarii is 8500 I think. I'd have to check 科学する麻雀or統計学のマージャン. they both have this info, as it's the basis of 押し引き. you can tell the value of open hands by looking at the melds. the most easily discernible expensive open hands are: dora pon and honitsu/chinitsu.

reading open hands often comes down to looking at what yaku the person might have. if you see someone chii 789m, then they either have 789 sanshoku, ittsuu, chanta/junchan, yakuhai anko/pair (potential atozuke), or manzu honitsu/chinitsu (or sananko, kek). based on their discards you can usually narrow this down further, and then you'll be able to tell their value roughly

when people discard the dora then they are usually getting pretty close to tenpai, iishanten is probable (but it also depends on what the dora is)

Well since no one is in riichi and dealer has only one call, I don't think it's legitimate to play safe. It's very hard to read closed hands (or hands open with only 1 call) it's not worth doing yet.
You can still get tenpai in your remaining draws.

Still not done with the book because I've been playing a bunch of mahjong soul, but my first impression is still accurate so far:
It's a good textbook for the basics that goes into a lot of detail why a certain discard/shape/strategy is better than the alternatives.
It also has 85 numbered "what would you discard"-questions (some with multiple A/B/C variations), so it actually has more content than the 80 shapes book, without being filled with the author rambling about random stuff (pic related), comparing wait shapes to noodle dishes and literal blog posts titled "you don't have to read this".

>rambling about random stuff
Yeah, I can imagine how that might not be to everyone's liking. I didn't mind it though, and I can relate to some of the blogposts (like the one in which he misread his manzu tiles).

The book I've been reading lately is pic related. The OP pic is from this book, too. Some of my biases are being exploded, like I thought that nakasuji 456 was less safe than suji 2378, but it's actually the other way around. The prose in this book is not so great though. It's usually just "let's take a look at [graph x]", "we can see that y > z. let's riichi when this is the case.", "we have now looked at this case.". It's pretty dry, but after a first few chapters I didn't mind, as the content is very interesting.

Another book came out based on みーにん's data, so that one might be worth checking out too. >https://note.mu/meaningless777/n/n304b08230700

Yes, as long as you can somehow interpret it as 1 pair, 3 sequences set, and one last sequence waiting on 2 sides (23, 34, ... 78), it's pinfu.

Are tiles really that fragile? Also I've been thinking if anyone has ever thought to try and play mahjong with cards (obviously would need a special deck). I figure it would work to some extent, though it would require some changes, like everything to do with the wall. But cards are infinitely easier to deal with and carry around than tiles.

Seems like they do have them already.

4p riichi probably has the biggest EV. Just think about it: although 4p is about 5% more dangerous, if you don't deal in with it, you're gold. 8 tiles of 369 > 4 tiles of 1s+4p.

being dama doesn't really help either, as shimocha and kamicha are gonna betaori either way. if you take the worse tenpai you're helping toimen because he's less likely to deal into you and more likely to tsumo his own tile

Yeah, you're in yakuless tenpai (since you can be in tenpai, that is - having a valid wait on a shape - without satisfying any yaku) for the sake of not losing points when the round comes to a draw
Same if you're in tenpai waiting for a tile that is guaranteed to not come, because for example all four copies of the tile were discarded before you reached tenpai

The article is confusing because it doesn't distinguish the different types of keishiki tenpai carefully enough.

(i) No yaku tenpai.

(ii) Tenpai with all winning tiles visible (dora indicators, discards, called tiles, closed kans by other players) and not in your hand. This isn't called keishiki tenpai, but karaten ("empty" tenpai). Whether it has a yaku or not is irrelevant, because you can't win with this anyway.

(iii) Hand is one tile short of four groups and a pair, but it needs a fifth copy of a tile in your hand to be completed. This is the second type of keishiki tenpai in the Arcturus wiki, which is much rarer and yet occupies the whole second section of the article. The Japanese Wikipedia article classifies this as being under karaten rather than keishiki tenpai.

Under typical rules, (iii) doesn't count as tenpai at all. Tenhou sort of does this, but it only looks at the part of your hand that isn't part of a chi/pon/kan. In other words, if you ankan a tile and end up having a kanchan/penchan wait for that tile, Tenhou will count this as tenpai; on the other hand, a shape like 2222345555999 would be no-ten, since it's waiting for 2 and 5 but all four copies of each are in your hand (and not part of a chi/pon/kan).

>> No.21309793

I fully understand what you guys mean now.

I played a bit on tenhou, and every game most people keep closed hands and like most games seem to end in a mangan, where on mahjong soul every single hand ends with tanyao 1 dora. It's actually pretty frustrating.

So many second places. If I played as aggressively as at the start of the year, some of them would've probably turned to first places, but some of them would've turned to fourths. I always hear people say that you "shouldn't really pay extra attention to avoiding last until 7D", but I think taking the choice that is a surefire 2nd vs a flip between 1/4 is better (and I think that this falls under last-avoidance thinking). What do you guys think?

Strictly in Tenhou's dan system, I'd take eternal 2nd over fluctuating 1st/4th. It's still positive in rank point and likely net positive in rating.
However, in tourney system like in Sega MJ or in IRL competitions, playing to win is better approach. Playing safe feels disrespectful towards those events.

Mahjong soul is a lot easier for newcomers (tutorials and help indicators), has cute girls and the general skill level is pretty low.

Tenhou is where you play "for real". The ranking system is really well done so you can get better over long periods of time and get into room for better players as you get better. It's where you can get the "competitive" fun.

Mahjong Soul is way too fucking fast. The 60 second thinking time is fine but if I or someone else wins it only gives you 3 seconds to look at their hand or your own hand (since with me being new to the game sometimes ron or tsumo pops up without me actually knowing what it completes in my hand) and that isn't enough time for me to look over the hand and see what it's about.

Finished reading 統計学のマージャン. Great book, I'll probably be thinking about the data in here while I read other stuff. Going to start reading Hirasawa Genki's よくわかる麻雀の勝ち方 that anon recommended. I also read a bit more of the JanngoroK nanikiru book, and while I got through the elementary tile efficiency part with only like 2 mistakes out of 20, it got pretty hard afterwards. I got both problems in pic related wrong for example.

A noob approach, let's see how wrong I am:

1: I would definitely keep the 789m789p89s for a wait for a sanshiki, as well as the S for a possible yakuhai (or at least to keep as a pair); the problem is with the remaining 45m45s, as I would have to break one of these apart and idk were to start, though my intuition is telling me to go with 4s
(I know the answer is whether to go for a two-sided wait or a sanshiki but I don't see why wouldn't I risk that edge wait)

2: This is less obvious to me, because even if there's a sanshiki potential, not much really is there (23m123s/234m23p or 79m89p789s, the latter forgoing dora but waiting on 2 tiles instead of four); ultimately, I think I would fold 2234m and try to keep 123s, because I'm a greedy boi for that dora; I'd sack 2m because there can always come a different pair, we're still early in the round
(is the question whether I would go for it at all? Because if so, I don't think so, though I would try to meander around the possible 789 shape as long as possible, but ultimately imo it's too shitty to play offensively)

1. 4s, I'd keep sanshoku because it's only 1 of 3 sequence left for that. The best scenario is 4 han guaranteed, and at the worst case of 89s tenpai wait, at least 4s sakigiri can be deceiving.
2. 8p. 2 of 3 sequences required for sanshoku and both have bad wait so the prospect doesn't look good. 8p first to at least keep possible junchan if 1m was drawn.

Guh, retard alert, I thought it looked too simple for a 南; that kinda makes me wonder if those shouldn't be ditched for an attempt to add pinfu to sanshiki, where those 45 shapes would be ideal - though I'd need to get 7s first and then commit to one of them, because tanki wait's a no-no there

Ryanmen ryanmen iishanten is much faster than keeping the penchan, and riichi pinfu dora is already decent value with a chance for mangan.

Since you've still got the 8m kanchan, breaking up the 89p penchan here won't speed you up significantly. You won't have pinfu either, so you should compensate with sanshoku for mangan.

Fuck sanshoku. Tempo is everything. Be sonic, go fast. Discard 8s and now you wait for 16 tiles for a perfect riichi pinfu 1 dora tenpai with ryanmen 8 tile wait. A single ura dora and it's mangan.

If you discard 4 or 5 and you'll be waiting only for 12 tiles. And with 66% chance you'll be stuck with a shitty 4 tile corner wait. Riichi, sanshoku, 1 dora. Guaranteed mangan, but it doesn't benefit from tsumo or ura dora (only from them both combined).

This one is similar to another very common form of WWYD such as 112378m78p123789s where you have to decide between locking in a pair (which has higher immediate ukeire but a high chance of being stuck with a bad wait) and locking in a ryanmen (which has lower ukeire but guaranteed good wait). The strategy goes that you should lock in the pair unless you've got an ankou or a consecutive sequence, like 112378m78p123999s or 112378m56778p789s, where you can easily reconstruct a pair elsewhere in your hand.

>> No.21345672

>>21345622
I thought the strategy went "decide whether you need fast tenpai or good shapes and judge accordingly". Either way, it's not quite the same situation here as a bad shape is basically guaranteed.

discard 2m: 20 tiles
discard 4m: 8 tiles, but you can chii them, so if we take "chii is 2x faster" as a baseline then you can look at this as basically 16 tiles

closed speed is extremely in favor of discarding 2m, I think if the player is the dealer then it's possibly better to choose to discard 2m, as the oyarii is worth it even if you end up with a 7p penchan

discarding 4m has the advantage that you can take chiiten. although you are more likely to not be the first to tenpai, it is easier to push back if the conditions are right.

it also depends on whether your kamicha is even likely to discard 8m or 7p. if they have 5p 5s or some other crazy discards then these tiles might not come out at all

I'm not 100% convinced either. Although in East-1 it's common to go for big and potentially slower hands, I'm not sure that the expected value is that much better if you get sanshoku. We'd have to check the EV of both the 7s tsumo and the ryanmen tsumo case and then multiply them by 4/16 and 8/16 respectively, add them, and compare that number to the EV of the pinfu hand. I can't check these right now.

One thing that's harder to quantify is the value of being able to open up the hand. In this case you can take chiiten extremely fast (16 tiles), meaning you can quickly take tenpai if something happens that you need to react to (riichi, dorapon, 2fuuro, etc.). I have a hunch that the EV is not that much higher and this is what makes the sanshoku more worth it.

As for all things, it takes a bit of practice.
For flipping tiles, you have to hold on tight and push the outer tiles inward. Use your thumb to hold onto the 2 or so outer tiles on each end.
For flicking dora, make sure to push the tile about a third of the way before pushing downwards on the tile to flick it.

so discarding 4s gives an overall EV of 1833+1800=3633

But mahjong is also a social game, you get to meet all sorts of people and you get to see their personality reflected onto the game.

And if you go for kokushi musou from that shape EV will be 32000. That's not how it works. You need to take into account probability of drawing and getting that shape.

It's 5th turn. Let's imagine that all required tiles to complete our hand are not present in any of the player's ponds and won't be discarded by anyone else. So you can't call any tiles and you can't win by ron. Also if you don't win in 2 turns by tsumo you die from heart attack. During your draw on turn 6 there will be 35 visible tiles (13 in your hand, 21 in players' pond, 1 dora indicator). During your draw on turn 7 there will be 39 visible tiles.

So what is our EV in 2 turns?

Discarding 8s and going for pinfu will give you 16 tiles wait. 16 out of 101 tiles = 15.84% chance to draw the tile on turn 6. After that you have ryanmen wait. 8 tiles out of 97 remaining on turn 7 is 8.25% chance to win. Riichi pinfu tsumo dora 5200 * 0.1584 * 0.0825 = 67.94 EV

Discarding 4s and going for sanshoku:
8 tiles wait to complete 45m triplet. 7.92% chance. After that you're stuck with 4 tiles wait. 4.12% chance.
Alternatively you can draw 7s (3.96%) and then one of 8 tiles to complete 45m (8.25%).
8000 * 0.0792 * 0.0412 + 12000 * 0.0396 * 0.0825 = 65.36. I.e. less then going for pinfu.

Obviously I used a simplified model that didn't take into account win by rons, suji trap, possible ura doras and other shit. But for any position it shouldn't be too hard to calculate expected value. It's not a pocker where you can bluff. I'm surprised no one wrote a bot that would wreck all pros simply by playing the odds.

You can't ignore those. Major part of securing sanshoku is that you can opt to stay dama for 4 han and you can even open your hand for 2 han.
I can see how that calculation works in one-player nanikiru question, but it's not solitaire. EV is helpful tool to measure decision, but I don't think those tokujou bots only use EV for their decision making logic.

EV is points multiplied by agari chance, so kokushi musou will never be 32000.

Also my last post has a mistake, as I wasn't actually looking at EVs, but 局収支 (I'm not sure whether there is a common translation for this term), which takes into account agari rate, deal-in rate, agari points, deal-in points, ryuukyoku, getting tsumoed on by someone else, etc. The data is from the みーにん book.

Also, 16 tiles is 33% more than 12 tiles, but the average 局収支 of the sanshoku variant is 3600, which is 38% more than the pinfu variant's 2600. I'd choose the sanshoku based on this.

You could say that pinfu is faster and it would be better to choose that in a round where you don't care about points and you just have to agari (like oorasu), but even that falls apart because you can probably get open sanshoku tenpai faster. It seems to me now that sanshoku wins in every round.

(Except if you have to push and dropping a ryanmen is already unsafe by the time you reach this 牌姿)

Dealt in twice today while having safer tiles. This is the shittiest feeling, and I don't know how I could avoid doing stuff like this. It's not like I don't know which tile is safer, it's just that I end up overlooking stuff. (Or maybe here I was possibly thinking of taking keiten if I can, and then I ended up pushing what I would've pushed if I got keiten even though I didn't get keiten) Luckily I was still able to avoid last, but when you deal into a mangan/oyaman in the east round then it's like playing the game on hard mode. I guess I should improve my condition outside of the game so that I can concentrate better or something.

By the way, do you guys have any methods on dealing with misses? The only thing I do is look at the replay every time I feel like I made a mistake. Often I make very simple ones that I notice immediately, and it makes me frustrated.

I compared the speed to tenpai and the value of each tenpai, the so-called expected income (局収支). The expected income is the estimate of how much you'll get on average with a certain tenpai.

I told you it's a table lookup. Agari ritsu for 先制 (i.e. you are the first) riichi ryanmen at the eighth turn is 57%, it's written down in another table. That's why expected income is lower than you might have expected.

Why are mahjong players so autistic and confrontational? I haven't even read what you guys are discussing but I'm feeling really bad for you. Go and drink a beer with friends instead of getting angry about Chinese dominoes.

Why did you take values for 8th round? Why not 12th? Why not any other? At least now I understand what exactly you don't understand.

Exercise >>21345328 clearly says it's 5th round. And the chance of being in tenpai on 8th round after discarding 8s and 4s are completely different. No, you can't say that 16 being 33% more than 12 means that the chance of getting to tenpai is 33% more. That's not how it works.

Just stick to the facts then.

I actually made a little calculation myself because I was bored, seems like the sanshoku has a slightly lower EV (~15%) if you only count tsumos, but the suji trap and possibility of open tenpai make it slightly better for me imo.

The best model I can come up with requires table from >>21358393 for every round. Then I need to multiply each value by chance of going into tenpai considering remaining tiles. Then I need to use conditional probability formula for every single round. That's insane amount of calculations.

I had an 1s which was also genbutsu, and I could've noticed that kamicha didn't drop any pinzu, but this is still extremely gay.

So declaring ron on that hand in Tenhou doesn't even give you mangan? What a joke.

Also this happened to me just now. Thinking back, the hatsu discard might almost have been a mistake, it could've become chiitoitsu. At least that's what it looked like. Wouldn't have complained about stacking some other yakuman though.

Had a dream where some guy was talking about riichi stuff to an audience (in Japanese). When he finished, he told us that we may come up to the stage (which he called forest for some reason) and suggest solutions. I went up there but the tiles were on a table with food and other shit and I couldn't really understand what we were supposed to do.
