Endgame Analysis In my recent game against wildpops1000 I managed to simplify to what I thought was a won king and pawn endgame (with 31...Nf3), only to suspect later that I'd allowed a draw.



The position I have in mind is after 46.f7 (above). It seems to me that, due to the unfortunate position of the Black pawn on h6, there is no way for Black to win the pawn on f7.

Therefore, the lines where Black allows the f-pawn to queen while taking the remaining White pawns on h5 and b6 seemed the best route to a win. However, during my analysis I was unable to find a method of escaping the checks or forcing a trade of queens. (I therefore delayed entering this endgame by playing 46...Qd4 with the hopes of my opponent blundering with 47.Kh6-+). It seemed that this queen and two pawns vs queen endgame was also a draw (a suspicion that was confirmed after the game by the six piece tablebases).

That leads me back to trying to win the f7 pawn after 46.f7. Rybka seems to love this position (she gets stuck on -4.81 up to depth 27), but I'm not so sure.

My question is this: is there a way to win this pawn, or is this position drawn??

Looks like a draw The only way to win would be to take out both h and f pawns, which can't be forced.

I would try 1.Qg4 to tempt White into 2.Kh6?

Yup... I've found some very similar positions in Dvoretsky's Endgame Manual indicating that with proper play, White has a draw in this sort of position. A pity, then, that I traded down to it. :(

Thanks for the reply, Marin. Good luck in your games!

It seems... ... that there's nothing doing with this sort of thing, neither:
46...Qg4+ 47.Kh8 Qf5 48.Kg8 Kxb6 49.f8=Q Qxf8
50.Kxf8 Kc5 51.Kg7 b5 52.Kxh6 b4 53.Kg7 b3
54.h6 b2 55.h7 b1=Q 56.h8=Q (=).
