($6.50) AK midstages facing 3-bet shove

[sixfour]

Coldcaller is unknown, shover is competent multitabler who's playing this level despite having average buyin of $50ish, about breakeven profit and ROI on sharkscope. I don't believe that this is a squeeze. Our play is? Easy fold?

Yeah i fold here, he certainly has something here and the only we are beating is AQ IMO. I don't fancy flipping for this amount equity.

This is pretty close I think, but you're in great shape so fold.

Lay it down you have so many chips to abuse people later.

With these stacks I fold. If you had like 1500 I'd push.

Yeah, I did fold in the end, coldcaller had 99, reraiser had QQ, board xxxxK obv - so if we're folding this here, how short would the effective stacks need to be to call the 3-bet? I think I'd probably stack off if I started with anything less than 2k here, opinions?
