200NL--6max--Top two with straight on board

[JasonP530]

Villian is 53/12. Seems donkish. I have 192 and he covers.

1 limper, Villian limps I make it 12 with KQ. Only villian calls.

Flop is Q96r. He checks and I bet $23 into the $26 and he calls.

The turn is a K, bringing a heart draw. Villian checks and I bet $58 into the $71. He checkraises all in for another $100.

Easy call? This isn't a turn check behind, is it?

Thanks
