[The Truth]

1. bankroll is plenty big enough for this game, so not worried about bankroll concerns in making the decision.

2. the raise means a good bit id say hes got at least KKxx double suited.

I agree with reraising to 800(pot) to try to knock out the other player.
I wanna see if anyone has suggestions of how to play this both ways.
if you raise or dont raise, and either way the 3rd player comes along and flop comes:
6 7 9 all hearts.
they both check to you.
