I was one of the chip leaders and raised with AK

Another big stack to my left called

Flop KQ7

I bet he called

Turn K

I bet again, but on the smaller side to get worse hands to called

He called

River was an 8.

I bet about 40% of the pot, which was about half his stack.

After some thought, he went all in.

I called and he showed QQ for a full house, leaving me with a small stack.
