It's also good for balance against regs.
Besides, what else are you going to do? Chasing your draw or folding seem like inferior options.
I am also looking at your pf range, why is it that, for example, you include Td9d and Th9h but not Tc9c? Also with a PFR of 16% it is arguable (not impossible though) whether he raises stuff like 87s-T9s, A5s-A8s and 22-66.
Now write us a piece on the EV of your semi-bluff, say if you make a half pot-sized raise. Split his cbetting range into hands that fold, hands that call and hands that shove over and do some math. Then should you call if he shoves over with the shoving range you came up with?
Note: this can get quite complicated, so you will have to make some simplifying (conservative) assumptions, such as "when he calls I will only win 25% of the time in the end" (either because you will go to showdown and loose, or because you will have to fold the turn). For starters, you can even start by assuming that he will only fold or shove over, never call.
