Is calling OK here?

[Munga30]

PP Micro limit. Table is only loose and passive. EP and MP limpers to me in the cutoff and I limp with ATo. Button limps and BB checks, leaving 5 sb in the pot.

*** FLOP *** : [ Th Ts 9c ]

Checked to me and I bet. Button, EP, and MP call. 4.5 bb in the pot.

*** TURN *** : [ Th Ts 9c ] [ Kc ]

Checked to me and I bet again. Button folds, EP calls, and MP raises. MP seems like a straightforward player from what I've seen. What range of hands do you put MP on and what do you do?

I call and EP calls. 10 BB (after rake) in the pot.

*** RIVER *** : [ Th Ts 9c Kc ] [ 2d ]

EP checks, MP bets, I call, EP folds.

What do you think?
