I guess he could have a set of 9's or 4's, if he thinks I'm betting the draw I'm already setting myself a bad price therefore he could flat the flop and raise the turn if no heart comes.Tricky line though. If he thinks I'm betting a weak queen I dont see him raising that much on the turn because he's chasing away value. I dont see 88 calling a flop bet of that size but possible i guess.
I do agree a combo draw is the best I can hope for and calling with the hope of hitting the bottom end of their range is probably not a good idea(hope I'be used that term correctly)
