There's a chap on here I regularly beat on the blitz site. He chalked up a win the other day - the first time to my memory he hasn't either had a phone call or suddenly been tired before abandoning the game. No class.
I don't mind a bit of trash talking in OTB blitz but over the internet, where I've got nothing invested in the game, I'm happy to walk away from the board and do something more productive until I'm timed out. kind of inane.
