There's one thing that gets me annoyed after playing a chess game: losing it due to lack of concentration.
When I play weird openings and my opponent defeats me. :D
Zeitnot.
Losing on time in a completely winning position is the main reason I'm ever annoyed.
Losing by bad connection in a winning position hahaha, this only happens on online chess :)
Imagine you play against a GM and you have mate in 1 and suddenly... hahahaha
what annoys me the most is losing a chess game;)
Good answer^ Covers a lot of ground.
I hate when supermodels in underwear sit on my lap with a glass of whisky in one hand and start talking in sexy voices while i'm playing a very sharp variation of the scandinavian.
Also, when your opponent swindles you is pretty terrible... :-(
