I was playing on line, cash game, 6 players, new table with unknown images. Had about 90 times the blind and was covered by villain. Villain opens for 3x the blind and I have Q7 suited in spades in the big blind. I decide to call. Fold is a possible play as well, but I figure Q7 suited is slightly better than an average hand. 3 people to the flop.
Flop is 5 spades, 6 club, and 8 spades, giving me the open ended straight draw and queen high flush draw. At this point, I think any option other than check fold is acceptable. Check call, lead out, or check raise are all viable plays. For this hand I decide on the check raise.
Villain, the original raiser leads out for 2/3 of the pot. Other players fold and I check raise for 3x villain's bet. Villain then thinks and reraises for almost 3x my bet. A call would be for more than half my stack so I immediately remove this from the option list. It is either all in or fold. A call also puts you in a tough spot as if the turn blanks, you really can't call another bet.
Villain's likely holdings at this point are either a set, an overpair, Ax suited in spades. Unlikely but possible are pocket 7's, 2 pair, with a very remote possibility of the made straight, unlikely since villain was the original raiser. Very unlikely is air.
What would you do? In an effort to not be Rotty, I will let you know my play after comments.
