Final Table Pre Flop play in Bodog 200 35K Guar

[TripleNet]

This hand bugged me after the tournament was over last night. I will do my best to recreate it manually since I do not know how to use a hand converter with Bodog.

8 players left in tournament.
Blinds are $2000/$4000 with $400 ante

Villan is UTG with $39,360 and shoves all-in. Villan had basically been playing push/fold poker and was the 2nd shortest stack at the table however he did not seem to me to be getting to out of line with his pushes in that he seemed pretty patient but I had not seen him show down any hands.

I am in the small blind with $76,819 (3rd in chips at the table) and dealt AJ of Spades and it is folded around to me. I agonized over the decision of whether to call or not and eventually folded.

Thoughts? Sometimes I feel I get too tight towards the end of a tournament and this was a situation where I should of looked him up.
