$6 buyin micro MTT, 331 entries, 4 players left, A6 os, first to act

[Ferdinand Peelen]

Last night I played an MTT on Paradise Poker -$6.60 buy in, 331 entries. We're down to the last 4.
approx pay out structure last 4:
1. $536
2. $340
3. $230
4. $155

approx stack sizes
UTG: me 75,000 holding A [img]/images/graemlins/spade.gif[/img]6 [img]/images/graemlins/diamond.gif[/img]
B: 210,000
SB: 80,000
BB: 130,000

ante 500 SB 4,000 BB 8,000 will go up in a few minutes
Pot 14,000

I've clawed my way up from 40,000 with 3 all in moves in the last 8 hands, all of which got folded round (remarkebly enough). I sense that people are getting fed up with my blindstealing and I won't get away with another attempt without getting one or more calls.

What to do? fold, call, raise half my stack or shove?

NB: I shoved, got called by SB holding A [img]/images/graemlins/heart.gif[/img] Q [img]/images/graemlins/diamond.gif[/img] and lost

I tormented myself afterwards thinking I did the wrong thing by moving all in. Any thoughts?
