20+2 PP Speed Sng AK2 vs 2x Action

[Seeeno]

Okay I found this Hand on an other Pokersite, where it was talked about in a Thread. Im really curious what you would do in such a spot.

Blinds 50/100, 8 player left.
Hero has AKs and sits in SB with 4400 Chips

2 folds, MP2 raises to 300, 2 folds, BU raises to 1000, HERO ???

I think it's a clear push at the 20+2 ... but there are guys saying they think a fold is good here, with the reason "this is one of the spots where many players think as the Chipleader they have to take the guys off the table and loose their chiplead"
