GGBMAN, what did you have?

hey ggbman,

I was watching you play 2000NL on Nov 17th. You had 33. Flop was 3A5. Turn was 5. River A.

On the river, you checked and your opponent bet $300 into a $750 pot. You check raised to $800 and he folded. How did you make that read? Why not just call?

I didn't catch any preflop action. I only saw what unfolded on the river.

Cheers
