[Catt]

I'd put in a few more river bets here. He got excited on the turn and 67 seems like a good candidate, as does a slowplayed 44 or 88. He sounds like he's so unpredicatable that he could have limped and then "slowplayed" his Q8 or Q5, but you describe him as wild and I'am ssuming he gets wild when he thinks he has a strong hand. In other words, without a more definitive read on him, I'd say the rivered Q was not terribly likely to have helped him; I think that either the turned 5 really helped him (67) or he flopped a set of 4s or 8s and slowplayed on the flop -- given my guestimates, I'd be willing to go a few more bets on the river and would stop somewhere around 5 or 6.
