For a start id never fold this preflop, id also lead for more on the flop, like $3.2 or something, when the sb checkraises id of thought his range is mostly 2 pairs, sets and combo draws like a3,a4 d's. Against that range were doing preety horribly so im happy in this position to just call his raise and hope to improve/reeval on the turn. Against a more agro villain id play differently.

I think even check folding to a big bet on a blank turn is the right play.
