Win or not?
The following game Game 3006810 was played against a fairly good player (probably better then his rating says). I was sure to win it, so sure that I didn't calculate a simple variation on move 44. I should have played Kd2 but instead I played Ke3?? and was only able to draw the game. It was probably possible to win it if you gave it a long thought but I got a little put off. Not that it matters very much that I lost but it would be fun to know if there is some theqnique to win this queen endgame, ofcourse that is trade queens or win the pawn with check. But how?
thanks,and sorry for being so lazy, yes that's right all I have to do is take the pawn, even without check. But let's say you have 1 min left on the clock and you want to be sure you win without having to risk perpetual checks...then I want to win the pawn with check, do you know how to do this without having to work it out. Thanks
?????
Even if the game is theoritically drawn, it is up to Black to prove it.....
All white has to do is nap the pawn, when black plays for pepetual, move up the board, use the pawns+queen for cover, and look out for double checks....
I'd say White has a good Chance of Winning.

A couple of month ago I learnt opposition with k+p vs. k and I've won or saved lost games by knowing this simple rule. In the same way I think it's pretty frequent that one player get's queen with check with both colored pawns on the board. Isn't there any 'perfect' trick to this endgame or no because it's more complex.
Originally posted by sleightjackeYou need to know about opposition, outflanking, corresponding squares. mined squares and zugzwang as well as blockading and what squares you can go to while still being able to stop your opponents pawn from queening (Rule of square, explained here...http://en.wikipedia.org/wiki/King_and_pawn_versus_king)

Its an area I'm studying a lot, as it doesn't suit my natural ability in chess. Its not about analysing, but putting into practice the principles I mentioned above.
This endgame problem uses most of the mentioned principles.
White to play and win.
The solution is below. Try to solve it yourself first.

White to move
The squares c5 and e4 are mined, meaning who ever enters one first loses.
