Hand 1 you say "assuming shorty wasn't there"... Are you saying that CO opens then? Or that UTG+1 opens but has a full stack? I like 3betting in either case.

Hand 2 ATOTHEC101 read it wrong I think saying it's fine to flat on the BU but I think playing in the SB changes things a tad as in we'd be more inclined to 3bet TT yet I call here a ton. I think as played you just have to get it in. From my experience, BU won't trap often enough at 100NL but that is totally generalizing.
