A win + funny hand

Finally got a win. Played well and got some playable hands.
This hand in particular against the chip leader was odd to say the least.
I knew he was extremely aggressive, re-raising this guy on my right lots of times. Basically I checked until the river to see him pop (which he did), not really concerned about draws, since with my stack I was going all the way no matter what falls.
But here's the hand (no we are NOT colluding :P)

roneewong said, "LOL?"

Then we were both heads-up.
I flopped the nuts and tried to use his aggressivity once again.
My bet on the turn (with two pairs showing on the board) was used to fake a steal and it worked, since he called.
I then bet on the river an amount that he could comfortably raise me with if he wanted to steal.
