Hi Terence,
I just read your message, a little bit too late.
I'm pretty sure you're friend received a Penalty for something else then that.
I'm the Tournament Director at Playground Poker Club for the WPT Montreal and I never gave a penalty for that. You can't force any players to put chips in a pot
if he doesn't want.
The problem is it's REALLY hard to prove for Collusion or Chip Dumping. With all the players swapping this day, it could happened more often and we can't prove nothing, so it's making our job way tougher to protect the integrity of the game.
An once again, you friend probably didn't tell you all the story...
Thanks
