Was this the wrong way to play??

OK, a little setup.

Outcome: ThatGuy wins t530.

Early in the tournament, but is ThatGuy so bad that he calls the raise pre-flop, bets a third of the pot on the flop, and then checks it down when someone calls and he probably has the best hand? Also, this makes me think he can play anything, at any time.

So he'll apparently lay down if he thinks that he's beat. What's he chasing here that he calls the flop and turn bets but lays down on the river? Trips?

After it checks around twice, he checks down top pair (even with a poor kicker) in late position, can we say loose-passive??.

Am I wrong to play this hand this aggressively, knowing that he can play anything and just call? If I check, ThatGuy is going to check it all the way down, and possibly one of the other guys will catch.

Maybe check it down after the Q hits on the turn? If you know he'll check, that's pretty nice for you, with an overcard out and a weak kicker. And you didn't have enough chips to worry about building the pot just in case you're good. What was in the pot already would've been a lot for you.

Against a normal player, checking the turn and river would be begging for a bluff, but this guy is extremely passive, so it may have worked.

He is an odd player that is for sure. I've seen people play loose-passive and tight-passive and crack alot of people. I also see some lose alot. Just be thankful this wasn't a NL game.

Um .... it was NL ...

Oh.... Shit...
