I think the point here is, when your M gets too low, and you sink from Red to Dead zones, you lose your ability to inflict ANY damage to anyone's stack. At that point, good cards no longer matter; you'll have to stand up against everyone still behind you. If you're first in in the cutoff, and your stack is not yet crucially low, the Gap Concept should apply to the blinds as well. In other words, even at attractive pot odds
, the BB may lay down his hand based on what he percieves as a weak holding if losing would damage his position in the overall tournament structure.
There are 2 keys to this play,IMO. What Harrington refers to as "1ST IN VIGORISI" is vital, but even more key is relative stack sizes of the players you're moving on. In general, you don't want to make this play against a large stack, 'cause the % of his stack at risk won't deterr him, and a very small stack can't be scared off a decent shot due to the precarious position they share with you. But against a middle of the road size stack, it's a reasonable play, and just hope you have 2 live cards.
