    hello everyone

     

    just a quick question about an endgame I just drew. I'll just show a position i wish to talk about (see below). In the game, white played gxh4, which I know ends up completely drawn (king controls the queening square, white's bishop can't, can sac my bishop for the pawn it's currently stopping and then just dance around the black squares in the corner with my king).

     

    My question is however, had white played kxh4, would that then win for white? I think it is but i can't quite work it out in my head.

    looks drawn to me, control one pawn with the bishop one with the king and prevent opponent's king from getting too near the central pawn with bishop. computer says about +0.9 for white but that means basically drawn since the endgame is so simple if it were won it'd read something like +10. also following through "best moves" giving it about a minute per move leads to a draw my repition quickly. opposite coloured bishop endgames are drawn usually even with 2 pawn lead

    According to Nalimov endgame table bases with White to move after 1.gxh4 Black loses in 13. After 1.Kxh4 Black loses in 22.

    O RLY? What's the continuation that is given after gxh4? It's just that, I mean I know I could be wrong and I'm crap at chess but it's surely a draw?!

    Go to the website yourself, set up the position after 1.gxh4 with Black to move and it will give you all the continuations.

    Can you post the moves?  I (coincidentally) just read the chapter this morning in Hawkins' "Amateur to IM" about opposite colored bishops where one side has two pawns, and the plans to win.

    Set the position up yourself after 1.Kxh4 and see all the continuations.

    Right the endgame tablebase only accepts the position with White starting from the bottom of the board.

    Kxh4 and Bxh4 both draw. Every other move and white loses Laughing

    er, just to clarify guys white is attacking toward the bottom of the board! 

     

    Transpo, thanks for the link. However it is saying it's not available :( I'll try and find an engine or something and have a look.
