It was a semi bluff.

I bet $1.00 to win $1.10. 1.00/(1.00+1.10)= 47% so if villain was folding more than 47% of the time this would be a +EV bluff in a vacuum.

I didn't know this at the time though, i just thought villain had a wide range wasn't going to connect with that board a whole lot so i would get a lot of folds and AJ seemed like a good hand to bluff with from my range.

Also i think this board smacks my range so i can rep alot of Kx KQ etc.
