Engine, or personal judgement? I've just resigned one of my games, taking the view that the position was lost. But on submitting it subsequently to an online chess program, I find that it gives White only a small edge. Who was right?

It's quite hard to calculate but it seems to me that white has a big+, even if he gives his rook for the N he still can reach an easy win.

Serious problems In my humble opinion black has some serious problems. On the ninth move you chose to play d5 (e5 is more logical I think) which locks in blacks white colored bishop. This problem is still on the board and I can not see an easy way to get rid of this. Because the black bishop is not developped it is also difficult to get the pieces to work together, while white's pieces are all taking part in the battle. An other big problem is space. Black has nowhere to go.

So if the engine thinks white has only a slight edge, the engine has some serious problems as well. But would I resign on this point of the game where there are still enough pieces on the board to try to change this situation? I think not. White can still make a wrong move. It is not a computer you're playing against. People do make mistakes!

I don't resign if there is a possibility of counterplay, and checkmate is not inevitable. Black has positional problems, but most of the pieces are still on the board. Hence you might yet generate counterplay.

I checked the game with Hiarcs 9 (a program that has held its own against top-ten GMs, and that usually whips Fritz 8 on my computer). It gives white a 1/3 pawn edge--hardly a decisive advantage.

Hmmm . . . When I let Fritz take several hours to look at this, it supported my suspicions that White IS winning. Black won't lose material in the next few moves, but in the long run the bad B and passive R's look like trouble. I personally wouldn't have resigned yet, but I would have expected to lose against a strong player.

I'd like to thank you all for your helpful comments. I agree that 9...d5 locked me in to a static position, and saddled me with a bad bishop. But I think my decisive mistake was pushing the boat out with 21...c5. If I had just continued to mark time, it wouldn't have been easy for White to break through. But in such positions I tend to lose patience after a time. I've lost many games that I might have drawn if I could have stood the boredom.
