I start with about $480, passive nitty guy limps UTG I raise $25 with AQoff UTG+1. 4 callers including both blinds and limper. Pot $125.

Flop: Q56 rainbow

Checks to me I fire $75. Folds back to BB, he check raises to $240. He started hand with ~$900.

Hero?

This was a must move table. The villain had just come from the must-must move a few hands ago. No reads on him. Max buy in is $500 so he obviously won at that table. He was young to mid 20's. No other info. He did see me lose a big pot a few hands before and I was talking so maybe he thought I was steaming.

I'm kind of new to 2-5 been a 1-2 player (and tourneys) generally. I'm not used to seeing people ever bluff in this spot so my feeling is that I'm behind. I bet 2/3 pot into 5 people so he is repping strong here IMO (Set of 55, 66, or 56). Are there aggro players taking this spot with lesser like KQ, QJ or semi bluffs like 34, 78, 89 ??
