That was why I said in my other post to play for a reasonable bet. There is no point if the game is never going to take place or as happened with you the guy now ducks you.
You need to find a way to make the game happen, not win some hollow ego victory that earns you nothing. I also said you needed to learn something about the guy so you know how to deal with him.
When was the last time you saw him playing for $2000.00? Probably never, so there was no reason to think he was going to play now. Figure out this guy and what makes him tick before you try anything else.
