villain is 49-35 with 11% 3-bet over 50 hands. I'm probably looking a little exploitable in that I've folded to his aggression a couple of times.

I call preflop figuring to be ahead of his range, but that 4-betting is going to get me into trouble or win me a smallish pot. I call planning to donk any flop with an Ace or King, and to check raise most other flops. Once the flop comes like this it seems the most obvious check-shove ever cos it looks kinda fos and i figure villain will be calling with high cards and/or any piece. I also think he's the type of player to put me on a one-hand range and figure he'll be expecting to see 44 a lot.

ridiculous? optimistic?
