Any comments?

Based on the betting, I'm reading BB for an A, with a middling kicker maybe. I'm pretty sure that MP2 found his flush on the river and has me beat. But for 1 bet on the river I can't let it go, can I?

do not fear the flush, the river is more likely to have made someone two pair than a flush since it was backdoor...definitely do not fold this for one bet on the river and i think a case can be made for raising the river...

[submariner]

I wouldn't have the cajones to raise, although I'm sure thirddan is right that a case could be made for it.
You cannot fold here. Many times you will be shown 2 pair here. If I did the math right, you were getting 9.5:1 to call here. You will win here more than 1 out of 9 times.
