I think your bluff will work against most players when they have a one pair hand like AJ, maybe overpairs as well. However, I think once they call the turn, they are likely to call the river. Also, if they are not willing to give you credit for hitting a gutshot with Q10 or 107, or two pair with J9, then they will think you either flopped a set or are bluffing, possibly with 910 or a pair that picked up diamonds on the turn. Accordingly, this type of bluff where it is hard to represent something other than a set might get called in some spots.
