Daniel Negreanu JdQd - all in?

[Tom22]

I was watching the tournament of champion last night and was puzzled by why Daniel Negreanu called an all in bet with Jd Qd. Doyle had raised all in with Ax. I'm not quite sure if Daniel was in the blind or not but he was short stacked.

He must understand that his opponent has either a pair of at least Ace high. In both conditions, he would be underdog. Why did he call this all in bet?

Usually when I'm short stacked in a tournament, I would still wait for a pair or at least Ace high to go all-in. Hoping someone would call with something like KQ which I would still be the favorite.

Could someone explain to me why Daniel called in this situation?
