Things that are against me:
1) I can only win mainly with a flush. And that flush comes 11% by the river.
2) BB might cap, and I might be paying too much to see the flop
3) There's chance of players acting behind me to fold, thus not giving me enough implied odds.
4) I figure UTG+2 is holding a monster, like AA, KK, AKs to be able limp and re-raise in early position.

Things that are for me:
1) Players could be loose enuff to call behind, and the pot would be very inflated for a flush draw.
2) I'll get a lot of action from the BB and UTG+2 when I hit my flush draw.
