9 SNG $5 + .50 End 8th 13 hands

Mixed play with poor choice last hand. I'm CO w/Ah 5s. Action folds to me and I open raise 2 1/2 BB (100), rest fold to BB who calls. Flop As 4h 6c. I pair my Ace. BB checks and I bet 120 into the 220 pot. BB raises me all-in w/1535 chips. Here is where it would be best I fold, but instead I call. Odds are he has at least an Ace with a better kicker then me. BB shows Ac 10d. Turn 7c. I have a chance here with an open ended straight. River Qc. Didn't hit and I'm outta there. Just not patience enough tonight!!
