4 SNG's and a double up

I played four SNG's last night. I finished third in one, fourth in two and ninth in the other. I only have one interesting hand from the four. In the ninth place finish, I pick up KK in early position and raise to $300. I get two callers. The flop is 4-5-7. I bet $400 and get one caller. The turn is a 10 and I go all in. The guy calls. The river is a 5. He flips over A-5. GG me. I might could've played it better, but after the 5 on the flop, I don't think this guy was going away. He was in til the river.

Then I played some .50-1.00 NL. I was only in for two orbits cause I doubled my starting stack pretty quick and took the profit. I started with $40. after about five hands, I pick up AJ suited.There is one limper in front of me so I raise to $4.00 hoping to pick up the blinds plus the limper. What do ya know. I get three callers (both blinds) plus the limper. The flop comes A-k-4. It's checked to me so I bet $5. The blinds fold, but the limper calls. The turn is a 7. I bet $10 hoping to run him off the hand. He calls. Now I'm thinking I'd better be careful. But I can't help but think if he had AQ or AK that he would've raise preflop. I'm a little worried about a-4 or something like that, so I go all in for my last $15. He calls. The river is a blank and he flips over A9. I couldn't get off that table fast enough. I started with $40 and left with $83. I kept thinking "I played that crazy." But that's the kind of play that you get in the low limit games.

I have to go to Little Rock on business this afternoon and won't get back until late so I doubt there is any poker played today.
