6 SNG $5 + .50 End 3rd 66 Hands

Mixed play. No horrible plays except maybe the last one. I had 56o as BTN and decided to try a blind steal by raising 2 BB's (240). SB folded, BB called. Flop 4c 8c 3h. I have an open ended straight draw. BB checks and I check. Turn 2d. I hit the high straight. BB bets 240 and I decide to just call. River Jc. Rats, possible flush out there. BB goes all-in for 1380 and I decide to call with my last 1090, hoping he only has a lower straight draw and not a flush. Unfortunately he has 56s and wins. As it turns out, if he didn't get the flush on the River we'd have just split the pot. I should have folded on his big bet.
