Why do chess player trash talk over a board game? I mean really, you're going to trash talk on a CHESS GAME? LOL
Just the nature of (some of) the beasts. Probably just to unnerve their opponent.
If it's an OTB blitz game, then the banter makes it a bit more entertaining.
To intimidate and psyche their opponent out but when their in trouble and running from you they don't like to swallow the spoon and take their medicine.
