2 HU $5 + .50 End 2nd 33 Hands

This one got off to a good start for me then I seemed to hang around a 250 chip lead, sometimes more, sometimes less. Then I got into a fatal hand.

Hand 22 I'm BB w/Ah Qd and 1525 chips. SB opens with a 3 1/2 BB raise (105) and I re-raise to 210, SB calls. Flop 10c 6c Jc. I have a gutshot straight draw, but no club. I check and SB bets 385 into the 420 pot. My assumption is they have high cards like mine, but not likely a flush, so I raise them to 770 and they re-raise me all-in and I call. They show Ac 10s, a nut flush draw and middle pair. A K or Q, not a club, would be nice. Turn 2h. River 4s. No cards for me and I'm down to 110 chips. I manage to hang on for a few more hands before I'm out of there.
