Bad play or bad beat?

[LetsRock]

I think it's pretty poor play by your opponent and he got lucky. Maybe a bigger flop bet (shove them in right away?)would have kept him from getting so interested? I think he got caught up with thinking he was best with your smallish bet, but somehow I doubt it would have made a difference. Only other option would have been to try for a check-raise (all-in) on the flop.

You can't fold really fold this hand with that flop, so I think you just caught some bad luck.
