23 ( +1 | -1 ) Q+K vs R+KSorry, I know this must be quite a common question so has almost certainly been asked before, but is it a win or a draw? I ask because I recently won a game like this, but my opponent made a mistake and I could not see any way to force the win.
73 ( +1 | -1 ) brunetti is rightThis important endgame is draw with a few obvious exceptions. If you want to learn the definitive theory about this ending, read the corresponding chapter in "Secrets of Pawnless Endings" by Dr. John Nunn. One thing!, this is a winning endgame (with the exceptions mentioned), but, you need to know exactly how to play it!, it's tricky and sometimes very long. If you know well the theory of this endgame, your posibilities of a draw in the inferior side are pretty good, because in many positions, even with perfect play, the winning is dangerously close to the 50 moves. Even a player of the caliber and experience of GM Walter Browne failed to win this ending against a computer, twice!
14 ( +1 | -1 ) impossible sometimes in practicecheck out the endgame databases...in some cases it is impossible in less than 50 moves. walter browne failed to do it v. a computer in the 70s i believe
