70 chips left - fold and hope to get 2nd?

[Damian UK]

HI all

3 left, just had my K9 busted by K5 (fullhouse) with K5x on the flop (5 on turn)(I raised on the button and followed thru to his bet from the SB [img]/images/graemlins/frown.gif[/img]).

So I have 220 chips left and am now on the SB

BB has 13K or so, the button has 1400

Blinds are 150/300

Button calls leaving himself 1100 - I have Q7 offsuit - is it worth me folding for my final 70 and hope the BB busts out the button for me to take 2nd?

thoughts?

cheers

Damian
