Any read on him? It's hard, I hate 4 card straights, but is he raising on the flop on a straight draw (unless he fits his screename and is holding 8-9 of hearts and hit the nut straight).. decent pot, but without a good read, pair of 7's isn't usually good enough to hold up... Set?

I might fold the flop because you're probably behind, and almost any turn card is going to be a scare card, whether it puts 4 to a straight or an overcard to 7s. The board is too coordinated, and you have to fold on the turn, especially to that size bet.

98s doesn't seem far off from him, i mean his name is suited connectors.

yea, but one day there was a guy named Q9favorite, or something like that, and he was in a hand where the flop came Q95 and someone bet and he folded!? WTF!
