So I get AA. Finally a good hand. I'm sitting on the BB, one limper, SB limps, I raise to $0.40. Fold, SB calls.

SB was a weird player, with an irregular playing style, couldn't figure out what he was doing, and he never got to a showdown so I didn't know if he was often bluffing or not on his irregularly large raises.

Pot: $0.90
Flop: 8c 7s 7d

He checks. I raise $0.60. He calls

Pot: $2.10
Turn: 3c

He checks. I raise $1.50. He calls

Pot: $5.10
River: 3d

He raises $4
me: ?
