I prefer squeezing pre but flatting is alright

on flop I think c/c > B/3B > c/r

c/c'ing keeps the fish in with worse draws should button c-bet, and you'll have enough equity to call most turns as well. B/3B'ing can be great vs aggressive opponents but the equity of a 22/11's Stack off range on this flop will likely be ahead of your hand.
