ok MP and button had stacks of ~11K
and after the flop action i had ~6400 left (i just realized that my original post was wrong in regards to my stack size after working the hand backwards).
after MP bets 2k and button calls the pot is ~9k so i'm getting over 4-1 on my money.

i actually put MP on 34 and button on a flush draw.
if either player had 78 the money was going in on the flop.
i figured i had odds to try and fill up.

i smooth called the 2K and the river was a black 5 giving me a boat and the effective nuts. because i think if anyone had 55 or 99 more money would have gone in on the flop, but who knows.

so now that i made my boat, whats my best chance to get paid?
the pot is already over 10K and i have ~4400 left.
i'm first to act and both of my opponents are good.
the only player to show strength in this hand besides myself is the MP but like i said in my OP he is very capable of laying down big hands and he has to suspect one of us has a set.
so who likes going for a checkraise, and who likes leading out...and if you like leading would you push the $4400 or bet ~2.5K?
