Early in a 4.4/180. It’s still early, but so far Villain is very loose/passive/stationy (50/6/0.3 over 16 hands). If anyone is paying attention, I am playing very TAGGy at 16/13/3.

UTG: (1430 in chips)
UTG+1: (2030 in chips)
MP1: (1490 in chips)
MP2: (1640 in chips)
HJ: (1440 in chips)
CO: (1130 in chips)
BU: (1410 in chips)
SB: (1520 in chips)
Hero: (2850 in chips)

Blinds are 10/20, Hero is BB with A [img]/images/graemlins/spade.gif[/img] K [img]/images/graemlins/spade.gif[/img]

Three folds, MP2 calls 20, three folds, SB completes, Hero raises 100 to 120, MP2 calls,

Hero???

So what could he be on, having limped in, then calling so far? I think he would have raised the flop with a set or an overpair on such a drawy board. So my best guess is that he's either on two pretty good overs (AJ+) or a draw hinmself. So, since Gobbo wants us to bet either for value or a bluff I either want to get value out of what may be the best hand and maybe get a call from AJ/AQ, or I want to fold out 55/77/88.

Waddaya think?
