5NL 6max - flopped trips in the BB, river double pairs board

[daviddem]

edit: I messed up the title, it's 5NL FR, not 2NL 6max, if a mod could change that?

MP2 is 100 / 0 / 0.4 over 4 hands
SB is 100 / 0 / - over 1 hand

It's the river that I am interested into here. His river range is busted flush draws, 3X, JX, and a bunch of pocket pairs.
