How to suck at poker

[Ghazban]

This was from over the weekend and I don't have the HH on this computer so its from memory. Villain is unimaginative and on the weak/tight side. I've played with him at least 4-5 times and would expect he sees me as being very LAG-gy in LP. I'm really only posting this so to force myself to think about the hand again and not play this way in the future.

Party 1/2 NL full, I have $200, he has me covered by a few bucks.

Folded to him 3 off the button and he openraises to $6. I have black KK in the CO and make it $20. Its folded back to him and he thinks a long time and calls.

Flop: T84r ($43 less rake)

He donkbets $20 into me. I'm fairly certain he has a smaller overpair as he plays AA very fast preflop. He's trying to see if I have big cards or a bigger pair. I call, figuring he'll fold to a raise but might continue to bet if the turn is harmless.

Turn is a J, putting 2 diamonds on the board (not a straight flush draw, though). Pot = $83 less rake

He checks to me, I bet $50 and he checkminraises me to $100. I call.

River is an eleventy-four of wands, he pushes and I call.
