Triple repetition of position. The positions after Black's 20th, 22nd and 24th moves are identical.
Threefold repetition - Wikipedia
Don't mean to be nasty, but it helps a lot if you learn the rules.
How on earth was this a draw? Am I missing something?
Sort:
I usually play against the 1000 level chess opponent, so I'm clearly not an expert on the game.
I was actually aware of the threefold repetition draw, but I thought they had to be consecutive. If they don't even have to be consecutive this raises some questions. (Which I guess I can research... but I'll ask here anyway.)
- I was clearly winning this game handily. The computer had LOTS of moves, but chose to make the same move 3 times in 6 moves, thus forcing a draw. Seems pretty unfair.
- What would stop me (when in a losing position) to move my well protected king back and forth three times to force a draw?

The draw is by repetition of POSITION, not by repetition of moves. In order for the position to be repeated, BOTH players must cooperate to create the same position three times. Any difference in the position, no matter how slight... creeping a Pawn forward one square, for example... breaks the repetition and rules out the draw.
Black moved his King back and forth from e8 to e7, and his Queen back and forth from b7 to a7.
White moved his Queen back and forth from d3 to d6,. and his Knight back and forth from d6 to b5.
The player who was losing badly would try to get a draw if possible, naturally... there's nothing unfair about that. Should he try to lose instead?
The question is... why did YOU just move back and forth?
You could have won Black's Queen on move 21 by 21. Qd6+ Ke8 22. Nc7+ which forces Black to give up his Queen for the Knight.
At worst, you could have made some other move that ruled out a repetition of position... a Pawn move, for example. The position isn't identical if a Pawn has been moved.

To add to what has been said, the positions don't have to be consecutive, they can be many moves apart.

To clarify, the ENTIRE POSITION must be identical, not just the position of one piece.
Okay, understood. Thank you for the clarification/education!
I've loved chess for probably 50 years but my brain just doesn't seem to be wired correctly for it. (Doesn't decrease my enjoyment... though it makes me feel pretty dumb sometimes.) It's not just the game that appeals to me, it's everything.
Playing chess with my wife, with a glass of wine, is classy and romantic. Plus, the history and personalities of chess fascinate me. I love reading about Morphy, Capablanca, Fischer; and the famous celebrities and historical figures who used to play.
Not sure why I related all that... guess I just wanted to share.
