Endgame study


Ray Garrison visited the chess club last night, and he and Tony composed an interesting endgame study with lots of interesting variations. White to play and win.

Hey Chris,

Thanks for posting this. Did you run through Fritz? Let's just say we missed some things! White is still winning though.

Looks like 1.Kc1 Ka2 2.c4 dxc3 (bxc3 3.b4) 3.Kc2! is the main line for not so deep, without the board calculation. The black pawn moves by h pawn will be canceled by symmetric moves by white h pawn.

2. .. Kxb3 is answered by 3.Kb1! (3.c5? Ka2!). Then white should win b and d pawns with some fine king moves and promote the d pawn. I am not sure about winning the d pawn without proper analysis though.

Ali,

You got the mainlines. 3.Kb1 is difficult to see! It's fun to put into the computer. Nice Q vs Q ending.

Yes, it is a nice ending. Pawns move to h4 and h5. White gives up c pawn in order to win the b pawn. Then white king takes the d4 pawn after some "shoulder pushing". Black takes the h4 pawn. The key move is Kf4! after black king takes the h4 pawn. Then the pawns are promoted and the black king is at g2. Queen checks at d2 and wins!

Nice! You guys should publish this in a major publications for chess compositions.

You flatter us Ali. Not bad for slightly drunk club players:)

Check out "A pawn study" (by M. Zinar) in my blog, and if you can put it in this blog so people can play around with it.
