Live small buyin: head up

[JayKon]

3 table live NL tourney, we've just gone head up and I'm in the BB.

Me: ~8K
Villian: ~32K
Blinds: 600/1200 (~3 minutes left in the round)

Villian has been playing like an agressive donk, but getting lucky.

1st hand head up he moves in from the SB and I have 7[img]/images/graemlins/club.gif[/img] 5[img]/images/graemlins/diamond.gif[/img]

I'm thinking that in order to play this guy I need to have more chips and don't really like the hand.

I decide that I might as well gamble the hand with what I hope are two live cards and if I win the hand, I should be able to play poker after that.

I lost the hand and took 2nd, but I don't really think thats relevent.

Opinions?
