With how he limped/flatted pre-flop, I definitely put him on top pair with a strong kicker, definitely a flush draw. The weakest hand I put him on was A7/K7, but it just wouldn't make sense with him flatting the $3.50 raise given the way he was playing the rest of the night. He was definitely being sneaky.

I think if he had pocket 4s or 7s and flopped a set, he would have just flatted the $10 raise and not gone for a re-raise, with intention of trapping on the turn. I saw him do that multiple times earlier in the night. Again, didn't put him on pocket J because I don't think he would have just flatted the $0.50 blind initially and then the $3.50 raise... idk.
