I think I should say one that I'm really good at beating, so my opponents will fall into a trap...
Mua ha ha!
What opening do you most hate playing against?
Sort:
Probably the Caro-Kann. I hate to see it as white as I like open positions and the Sicilian.
Scandinavian as white, Ruy Lopez exchange variation as black. I play the Philidor only because everyone I play OtB exchanges bishop for knight on turn 4.
Can be for black or white.
