Hmm.. The limp on the button makes me think he has sm-md suited connectors or 1 gappers. So with a flop of 6 10s 2s and the instant call is saying I'm not even thinking of raising or folding. I can see him holding a 910, J10, Q10, 67. With an overpair or top pair he might have to take a second and consider the flush draw. But with a TPWK maybe he just wants to keep the pot small trying to show stregnth with a quick call. Ofcourse with a overpair you would have prob seen a raise PF.

Him checking the turn maybe a flush draw but the bet on the river of only 2.5k doesnt yell busted draw to me. Seems more like a value bet. He wants a call.

What was the result?
