Tough one. I'd lean towards a call but they always have AK when I call.
Either's fine really. If you call it's probably +EV but you're risking your tournament life. If you fold you've got plenty of chips to find better spots and get better reads on the players. If he keeps shoving from that position then you can call wider next time.
After all the server problems yesterday I was refunded $37 for the 7 $2.50s that were cancelled. I'd busted another 7 before that so still ended up with a slight profit which isn't too bad. Today I played 31 games with 5 cashes: 2x min,1x 6th, and 2x 2nd. Pretty happy with that as both 2nds were against a huge stacked reg who I was unlikely to beat.
Looking at HEM it's been 400 games since my last win, that's well below average.
