Hold pawn position, since black can't possibly take any of them without allowing a queen to come into play.
Chase blacks pawns down with your king, black cannot reach either pawn to promote without white being able to capture both.

>>9387032
It's implied you're playing as White, since that's the board orientation.

>>	Anonymous Fri Dec 22 17:19:01 2017 No.9387048 >>9387033 how is that implied? that late in a game the kings could have moved sides and the white pawns are in their starting positions.

>>	Anonymous Fri Dec 22 17:21:40 2017 No.9387054 >>9387027 a way to make this problem a lot more interesting would be to move the black pawn in the center and shift it to the right by one column

>>	Anonymous Fri Dec 22 17:22:15 2017 No.9387056 >>9387048 Because otherwise White loses, there's no way to stop black from getting a queen immediately followed by another in 3 moves, leading to inevitable checkmate.

go for the black pawn on the right, black can't capture your 6th rank pawn because then you'd advance to queen
after you capture the pawn, depending on blacks answer, either chase the other one or move king to your pawns and push them to advance
this is 1300 problem at best

>>9387214
It isn't as easy as that. Black can advance the edge pawn also. Try to take one, and the other one can queen.

>>9387027
1. Kb3! e4 2. Kc4! a5 (if e3 then Kd3 catches both pawns in time) 3. Kb5! Kc7 (else Kb6 and c7#. If Ka7 then Kc5! e3 Kd6! Kb8 [e2? Kc7 e1=Q b8=Q+ Ka6 Qb6#] Kd7 e2 c7+ Kxb7 c8=Q+ Kb6 Qc6+! Ka7 Kc7 e1=Q Qb7#) 4. Ka6! e3 5. Ka7 e2 6. b8=Q+ Kxc6 7. Qe8+ forks the pawn before it queens.

I don't know shit about chess so I cannot tell you in fancy notation but obviously the white king moves to support his pawns and the black pawn frantically moves downward in an attempt to become a queen, but loses unless white really shits the bed

Anonymous Sat Dec 23 05:18:37 2017 No.9388318

There are two possible outcomes, both start with Kb3.

1) Black pushes the E pawn, in which case just chase it down.

2) Black pushes the A pawn, in which case ignore it/take it but prioritize getting to B6 then move c7#. Black will promote to a queen the move before but it doesn't matter.

>>	Anonymous Sat Dec 23 19:32:56 2017 No.9389401 >>9387268 then black wins after taking pawn on f7 :3

>>	Anonymous Sat Dec 23 23:56:10 2017 No.9389811 >>9387268 it's basically impossible for black to win. stockfish says it takes 19 moves for white to checkmate black

Anonymous Sun Dec 24 08:35:56 2017 No.9390329

>>9387027
I would move king to B3 first. If the black moves the A pawn then move back into A and run straight into it then move to B6 and check with the C6 pawn.
If black moves the E pawn then move to take it out then you have options, you can move back in front of the A pawn or move to B6 to do the check again because he will have to move the A pawn.
