Ma Flops It

It was limped preflop between Aaron La and Ning Ma blind on blind. La check-called for 80k on the [pc]TdTc7s[/pcn] flop.

He led for 160k on the 7♥ turn, and Ma called to the 9♥ river. La went back to checking, but Ma fired 400k. La tank-called but mucked when Ma showed ten-five for the flopped trips and turned boat.
