I find myself getting trapped too often with TPTK or TPGK by someone with a straight or a set. Typically they have position or will slowplay the flop. This is a .50/1 9 player game on stars and I will usually bet the flop around $3-5 (either to start or to a check), get called, bet the turn $7-10 and get called again.

Clearly the opp has something at this point or he is on some draw and has either connected or missed. I will typically repeat my turn bet if I feel he missed or will check if I feel he hit.

The problem is that the opp will ofcourse raise me or bet me at this point as well. The question is when do I call and when do I fold. Most of the solid plrs at this level don't seem to bluff too often since the typical passive plr will call them down. I have seen some bluffing though (a missed draw) but I can't say for sure how common it is.

I'm interested in people's approach to this situation.
