Just lost $400 for two reasons, one is that I did not bet aggressively enough and the second one was a sick river.

I am holding KA off suite on a $20/$40 table of 6 players. I am in good position and I am raising pre-flop to $80.

4 People fold and I am left heads-up with one guy which is in an earlier position.

Flop comes 4,5,K. The guy checks and I bet another $80. The other guy calls me and the Turn is a 8.

At that point I think I should have pushed all in (about, but for some reason, after the guy checked, I bet on $100.

He called and the River was an Ace.

I pushed all-in (about $150) and got an instant call. The other guy was holding 2,3 and had a 1-6 straight.

So sick..
