i find this complicated but interesting... i think the river is huge leak for me.

obviously if the cards were face up, there would be no problems with anyone, no bets would be called.

so then it gets down to how good your reads and your opponents reads are.. i think there's lots of risk against good players, but bad players (maybe me) are overly optimistic with top or second pair.

very interesting though as last time i played B&M, the river was a complete disaster (fed some huge pots and never seemed to get paid on my nut flushes).... i think check-raise is good on river with the right players but you definitely need a very aggressive player "to make the bet for you"
