MP2 had pretty much made this play all but four hands of the 19 I had been at the table preflop, opting to be passive in the blinds. Half the time he would C-Bet.

What's my play?

i take the free card and look what i do on the river. i don't like to get fancy with only a little bit more than the pot behind. a little bit more info about our opponent would be helpful. lag, tag? if he's tight he's sure got you beat by now - be it only AQ high - and doesn'T buy what you're trying to sell. i let go, this seems to be near the tournament start so there are plenty plenty plenty better spots to chip up.

edit: this is not a turbo, right?

He isn't calling the flop raise OOP with many hands he's planning to fold on the turn.

This smells like 99, 10's, 8's.. stuff like that.. Lets check

hadn't seen him show down a hand. table wasn't resisting him too much, so he was pretty much mowing them down.

no, this isn't a turbo.

Make him as long as it's kept cheap. As played, checking behind is fine. We've got nothing but overs on the turn and villain could have anything from air to a flopped straight, and could be playing anything from rags to a premium hand, but we'll never know if we don't get a showdown.

Though villain called, our raise on the flop appears to have slowed him down and we may see a showdown cheap. A showdown probably unravels the routine you say the villain's settled into.

Take the free card on the turn. He's called your flop raise OOP. He's only fired a CB 1/2 the time so he's not indiscriminately firing CBs at every flop. I actually think folding the flop would be fine since you whiffed and AJ sort of sucks in the early stages of a tourney.
