Endgame analysis

mrkint

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.

Curse of the opposite coloured bishops strikes again :0)

Drawn?  Are you kidding?

White has a lot of ways to win, 1.e5 being the most straightforward.

OK, now on a more serious side, assuming that you put the bord in reverse:

1.Kxh4 is of course the only winning try, but then there is no breakout plan- the two pawns are too close to each other. It's a draw.

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.

I was about to say something evil, but then I realized the poster had not understood that the board is reversed- so I deleted it.
