I would just shove pre. with the effective stacks behind being under 14bb. Only way I fold to villian now if he was extremely tight and or hardly ever reshoved giving you need @ 45% equity and I feel you have that unless he is shoving a supa tight range:

22+,A7s+,KJs+,QJs,A8o+,KJo+,QJo = 50.591%

AcTc                                            = 49.409%

make this decision pre – shove>fold>>>raise/fold

right here the only reason i would raise is if i had the intention of calling EVERYONE else behind. Easily call the BTN and BB and if we know the c/o and SB are capable of reshoving light call them too. if they're not spewy players then jam or fold.

All we've essentially done is put ourselves in the position to call off an 11BB shove which is now 3/4 of our stack with 2 micros at the table which we'd have a chance to pick off without damaging us too much.

fwiw – him having the 2 micros still to act behind him should strengthen his hand/range b/c he's more likely to showdown.

readless, i would fold to the 3bet shove as you did
