Hey guys, sort of an interesting spot on the river.

To begin, I am in position against a few droolers.  The game is built around one of them, player A.  Player B is fishy, but not as bad, he values hands after the flop reasonably well but makes huge errors preflop.  Player C is the best player of the bunch...his A game is spot on, however he is very tilty and spews if he loses a pot.

We are playing 6 handed and I begin the hand with 1200ish.  I raise in position with AJ hearts.  I make it 30 (we are playing 2-5) And I get 3 callers.  The flop is A55 with 2 clubs and a heart.  It checks to me, and 95% of the time I bet, but for some reason I elected to check.  The turn brings the 7 of hearts.  I have top pair and nut flush draw and it checks to me once more.  I bet 85.  Player A calls, player B calls, and player C makes it 200 more. Yikes.  I elect to call because I have a reasonably disguised backdoor nut flush draw and I feel we are deep enough that I will get paid if I hit since player c is a little tilty and will likely pay me off with trips.  Even tho player c is tilty, he just check raised 3 people on a paired board so I am giving him credit for a random 5.

The river is the 9 of hearts which gives me the nut flush.  There is roughly 1kish in the pot.  Player A leads for 275.  He has 350 left.  Player B flats the 275 with about 800 left.  Player C, the player who check raised the turn, folds his hand.  Action is to us.  Jam river, or flat?
