He probably had to go pay the pizza man.

I was once playing a long game, got called to lunch, spent 20 minutes eating, then came back and finished the game.

Not that I can see, your opponent probably just had something else to do...

Yes, 3...Bc5 is a variation! It's called the "Classical Variation" and it's rare but not unreasonable. Booby Fischer played it in serious competition a couple of times. I think 4.c3 is the most common reply

How could 13.dxc6 possibly be better than 13.dxe6 which wins a piece? Your comment after 13...fxe6 indicates that you are not yet awae that you have two minor pieces to his one.

22.Qa6 was a serious mistake  (22...Bxb6! 23. Rxb6 Bxb6 24.Qxb6 Rxf3!). I think you overlooked that your g-pawn was pinned, so that it did not actually defend the Nf6. 22.Nd7 forking both rooks won easily. And after 22...Rxf3? 23/Qxa7 wins for you. Black's resignation is just one of those mysteries

yeah, the pizza man saved me here. paulgottlieb you're right, 22. Rd7 would have probably won it for me, thanks

I just played a game where my opponent resigned in an equal position
