(50NL) Turn OESD: Poor semi-bluff?

[squashington]

BB and I had both been playing standard TAG and he seemed capable of laying down solid hands. In retrospect I'm not sure how I feel about my turn raise. If he flat calls and I blank the river my only hope of winning the pot is he folds to my river shove. But getting over 5:1 I don't see him folding if it comes down to that.
