The other side of the GAP

[NegativeEV]

General concensus on this board is that proper use of the GAP theory from TPFAP is a critical component of late SnG play (i.e. the GAP increases folding equity and makes late aggression profitable). Although I feel I'm adequately increasing my aggression to maximize folding equity and utilize the GAP theory when stealing blinds, I'm much less confident when on the other side of the steal attempt. Maybe my GAP is too large (high, big, terminology?), but I find myself laying down AQ, AJ, KQs, etc. when I'm on the bubble in the blind and UTG or CO raise to a level that puts my stack in peril (i.e. raise has me covered or forces me to go all in if I'm going to play).

I was watching one of Strasser's games on replayer and I notice that he called the CO's all-in raise of ~ T1000 from the big blind with AQo when his stack was ~ T1700 (blinds 100/200) and there were 4 (or 5) players left. The CO had A7 and the call put Stasser in a commanding position.... this is not a call I make. I'm not sure whether he had a read from previous games that influenced this call, but I'm curious what hands we should generally be calling with at this stage in the game when we have a healthy stack and calling puts the vast majority of our stack in the middle. I suspect that I'm being too tight in this situation.
