Implied odds with a player shortstacked?
In my poker career I have tried to play as many tournaments as a can, sit and go, MTTs, Rebuys, Add-ons anything. As an example lets say I am on the BB and am dealt 9s 10s the player under the gun is short stacked with 700 chips and calls the 100 blind. Everybody else folds to me and the flop comes up As 6d 2s. For some reason I check, the player goes all-in. He was crippled early in the tournament on a bad beat and has played tighter then something really tight up until now. I know easily he has aces with queen kicker or better. The 600 chips he put into the pot do not justify a call based on the odds I am getting but if I call and win I eliminate him and get a better chance in the tourney. What is the appropriete play here?
