As played when you chk flop, I just chkcall and can't think of a good reason to do anything else. C/raising folds out his bluffs
It's hard to call this a c/r. Dude bets 2c, it's as good as a check. I see it that we're simply being given another chance to lead the flop, with villain having given up his positional advantage. Flop "raise" is fine imo.
