Yes I noticed the inconsistancy. Like I said I didnt really have a read yet, it was more of a hunch (more of a generalization really since I had just sat down, had no stats yet and didnt see anyone's cards to see anything obvious).

I thought there was still a decent chance that I was ahead after he raised me, and by 3-betting it, it might help me clear at least one person out at the turn.

From what Ive seen in 1/2 6max is that people will play even TP as a big hand especailly against my seemingly follow up bet so I didnt see any reason to be too afraid I was behind here. I wasnt that afraid of the cold caller(s) because it seemed like they would call anything if they had any part or draw off the flop.
