My opponent resigned but I don't think he should have. Do you?

Do you think my opponent should have resigned? I admit I made a decent move on him but I didn't see an iron clad win for myself.

23. Nd6 will get his rook, is what I foresee.

I agree with ivandh, Nd6 gets the rook by revealing check then he is a major piece down

23. Qc6+ Kb8 24. Bf4+ Ne5 25. Nxe5 is all kinds of horror for black.

Though you aren't necessarily going to find either of the two winning suggestions. He might as well wait until you play one of those and then resign. But who wants to wait around to get creamed.

Yes, I think the position is sufficiently complex that resignation is premature. If you miss the knight pin, Nd6 doesn't seem to go anywhere, while Qc6+ is scary but not mortally injurious on its own.

For some reason, I like 23. Qc6+ Kb8 a bit better.

Probably because it's followed by 24. Bf4+ Ne5.

But also possibly because that's followed by 25. Bxe5+ Rxe5.

Or even possibly because that's followed by 26. Nd6 Qxd6.

Could be because that's followed by 27. Rb1+ Rb5.

But mostly likely because it's followed by 28. Rxb5#.

A timely and correct resignation.

Resignation deserves an exclamation mark

well, maybe he resigned a little early.. but maybe he saw 1 (or all) of the mating lines mentioned here (he certainly was in a bad position).. it would still need accurate play by you though to avoid throwing the game away..

Could he have saved the game if he played Kc7 instead of Kc8 for his last move?

No.

Personally I do not ever resign! My opponent has to kill me! I wait for my opponent to make that 1 really stupid mistake that will either let me win, or allow for a draw.

Black is horribly lost.... forget about seeing the mate, the fork on d6 is sufficient. I think that some players rated 1683 can be expected to resign such positions. Your opponent is a gentleman, you can expect more of the same as your rating increases.

See, I forgot that's how chess games go down in Texas.

BTW, it is ironic that your username is after a guy who knew when to hang it up.
