call is fine pre given stack depth. had SB folded i'd definitely prefer a 3b to calling, which is almost definitely what i'd do if i felt BU villain was at all familar with "blind stealing" and could fold to 3b's. i'd C/C flop and take it from there. 3b'ing as played seems pretty bad when we can call and keep 66+ in our perceived range (so TT+ might still put more money in against us, unlike if we check/3bet this flop).

fwiw, i think this can be a very good play against certain players i've played against who know we rep fuck all here and aren't afraid to put their stack in the pot based on that read. unforunately there are probably 0 of those guys at 2nl
