bad bet size or bad bluff???

I don't mind the raise PF; it is a bit much but with the antes in there and a SB that covers you, you want to discourage action with the KQ. Your PF bet is probably the reason why your villian just called, unless he is passive all the way.

You gotta shove that flop though. If villain calls with A high for all your chips on THAT flop without two hearts on the board, then you just gotta tip your cap to the villian.
By checking it down, and THEN betting on such a dry board for a raised pot on the river, you give him a chance to be curious. Villian gave you a chance to steal this pot, IMO, and you gave it back to him.

By betting PF and the shoving flop, you represent a big hand or PP to him. Can't leave your babies in the middle, especially on such a dry board where the first bettor usually wins.
