First, I'm going to link to the Steam thread I made about this.
Brock had slightly under 4k left, and went all in while raising. Sam folded, Claptrap and Ash called. I bluffed with a possible flush and went all in, Clappy and Ash folded. Brock got a pair on the turn, I didn't get my flush. Brock won and took all of my money.
I'm used to, in every other poker game I've played, and even in this one, if you go all in and nobody can match your bank, it gives you the excess chips back. I should have gotten something like 28k chips back, but Brock took them all, and I busted out.
