I lead the flop with my 2 overcards and the backdoor nut flush draw, but LP2’s raise was cause for concern. I called that bet hoping to find a heart on the turn, but mainly to avoid folding for one bet after I had opened the betting on the same round.

I didn’t really like the turn card- even though I now had TPTK, there were flush and straight draws out there, the BB had just woken up and the tight passive player behind me had raised on the flop.

What to do?
