From my perspective, a narrow win. Once you got down to 6 on the board, it was fun to see what shredderchess.com thought W should do. And W hadn't really started doing it, yet. I suppose you resigned because you saw that the general scheme. to disrupt your protection of the pawn, take it, then maneuver to a fork to get the rook, would be successful.

I personally don't understand how the win is performed either; I've never spent a lot of time studying those types of endings. However, you can see how the win is done at an endgame tablebase like the one available at shredderchess.com

Originally posted by dustycatif you know your queen vs rook technique, it's trivial after the pawn drops (after OP's Rb7, Qd8 seems to do the trick). although, from the atypical looking queen moves I would guess that wasn't the case here. I would've certainly played on against a human player at least until he showed proper technique.

about finding the optimal tablebase lines in this, or any long complicated ending, that's pretty much a pipe dream for a human. and stupid. precisely the kind of thing a strong player wouldn't touch with a ten feet pole in these kind of situations. instead you use good technique.

When the computer shows that I have a mate in X number of moves (I had one game where it said I had a mate in 51 moves!), I almost always win in FEWER moves.
What I have learned is that defensive technique is very tough, and very often my opponents play nowhere near the optimal defense. As an example, in the above game, I actually won in 19 (although I hardly saw any of it- I knew I was easily winning, but I just played good moves until the game resolved itself).
While we can't use tablebases here, we can use endgame books, and I agree with wormwood that the big W is more than capable of bringing home the whole point.

He's not really a 1600 is he? More like 2000 and probably better if his rating wasn't constantly dropping and rising...

During the opening you play to establish an advantage.
In the middle game you try to turn the advantage into a winning position.
The endgame is when you realize you are going to lose." - Saviely Tartakower.
