1) PRE: raise sizing is exactly what I'd do.
OTF: C-bet $0.35-ish/fold is so obv for my style. Can't b/c since Villain is too short to pay off well if Hero binks a Q OTT.
Then again, I C-bet a ton of flops, and nearly 100% when HU and I'm PFA. If you're going to try this, you must remember to slow play a lot of hands OTT, or you become supremely vulnerable to the float.

2) PRE: fold, as SC's play pretty terribly OOP with no reads.
