Correct Play or Wimped Out?

[banditdad]

I knew I was ahead on the turn against this particular player. He will raise and reraise with 4 card flush draw and set. I did not raise the flop because it is pointless against the BB, any piece and he will call or raise to the river. I don't have a clue what the SB was doing in this hand other than feeding the pot and hoping to hit his draw.

I feared a suckout on the river with someone holding QKA. Was I correct to just check or should I have bet out?
