two table tournament - chip leader facing short stack shove
I used to know this stuff, but my tourney skills have faded since I stopped playing online.
Blinds are $400/800. 11 players left in tourney, 5 at my table. Home game.
Villain is a very good player, understands short stack play and ICM. He is a short stack with 8k in chips. I am chip leader with ~21k. Blinds will go up in less than a minute.
Hero is BB (21k). Folds to Villain on the button (8k) who shoves. His range is literally any two cards. SB folds.
What are my calling requirements? I think it's something like A8+, 66+? How far off am I?
