I c/shove a rag flop vs a light 3better w overs

[kaby]

ipoker nl100 6max 100bb eff

villain is 22/18/3 over 300 hands
he has 3bet my btn open with ATo from the blinds, he has 3bet my MP raise with 89s from the CO, and he frequently 3bets my CO raise OTB, i've seen him showdown low pp's twice

i openraise MP with AQo to 4bb
he 3bets CO to 12bb
all fold
i call (?)

Flop (pot is 25bb) is 722r

i check, he bets 14bb, i shove?

there hasn't really been a lot of relevant postflop history but once i shove this i'm playing my good hands the same way in the future whether he calls or not fwiw
