Is this ok? He seemed very solid and he is up 600 bucks for the table, if that counts for anything. Honestly, what hands play like this? Has to be A[img]/images/graemlins/diamond.gif[/img]x[img]/images/graemlins/diamond.gif[/img] right?

why are you so short-stacked....honestly it was a push or fold decision on the turn....the river is a fold i guess but you shouldn't have a river decision here.

I would raise a lot more on the flop

He's not necessarily a big winner, he's more than likely doing the rebuy trick. Check out the HH and see if an extra $100 was added to his stack after this hand.

And, I'm folding.
