Villain is 10/3 over 450 hands. 5% steal and 55% vs-steal call doesn't suggest he has much of a brain.
Hasn't raised c-bets so far, but I only have 15 hands vs pfr on him so far (50% limp/fold)
Unfortunately no player notes on bet sizing... well he doesn't play many flops.

I really wanna r/f, but then someone without a brain might 3b shovel worse hands...
The more I look at this I really think call is best.
