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.

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
