Did I suck out?

[mcguw]

After this hand, I got a lot of uninvited comments about my play. Did I completely suck out, or did I just take advantage of the situation?

UTG +1 had a huge stack~1300 and was tight, typical, but knew how to trap well.

CO had just come to the table, so I had no read on him. Stack was $200.

I had slightly under $300

B&M 2-5 NL $200 max buy in
I was MP+2 and dealt AcQs,
Pre-flop UTG+1 limped, then all folded to me, I raised to 20 (standard opening raise at the table), CO flat called, blinds folded, and UTG+1 flat called.

flop was 3c 9d Jc (pot $63)

UTG+1 checked, I bet 30, CO flat called, UTG+1 folded.

Turn was 4 c. (pot 123)

I bet 30 again, and was again flat called.

River was a 10c (pot 183)

I bet 60 was once again flat called, and showed the nut flush. CO mucked his hand and said it was two-pair.

If CO showed any aggression, I would have likely folded the flop or turn. Granted, my turn bet was probably in error, however I think that this hand was less a suckout than poor play by CO giving me the win. Comments.
