Readless, I fold hand 1 preflop. CO has repopped an UTG raiser. 4 betting sucks, as does calling, as TT is hard to play OOP.
As played fold to flop raise, this has RIO written all over it.

Hand 2, again readless, just call flop raise and reevaluate turn. This could be air, a 5 or an 8, possibly 99 or slowplayed overpair. You pretty much define your hand with the flop 3 bet and let villain play perfectly against you.
As played I check fold turn.
