When antes kick in, I widen my opening and 3bet range while tightening my calling range.

33bb is gonna be around average. First factor I'm concerned about is how close we are to the bubble. If we're close, I'm looking to maintain this stack size without taking too many risks, so I'm gonna steal when I have the blinds well covered, and avoid confrontation with those who have me covered unless I have something I can't fold. Once we're past the bubble, with 33bb I'm looking to build a stack in an attempt to final table, so I'm widening my opening range, and widening my calling range vs shoves from shorties. Death or glory until I'm deeper than 50bb, at which point I steal lots and try to avoid big pots with marginal hands, while still trying to pick off shorts where possible.
