50/100 Folded to your SB, playing trash aces w/ >10xbb

[otctrader]

5-handed 50/100 (level just started), stacks evenly distributed ~15xbb, folded to you in the SB with 13xbb, BB has you covered by a hair. The rest of the table is playing fairly orthodox, so taking a siesta while they knock each other out doesn't seem like an option.

Shove A2o here? How about K5o?

Calling range is probably A6+, top broadways, any pair; BB is savvy enough to resteal so I'm hesitant to bump to 300.

A2o I shove, K5o I fold.

I ran the ICM/math if anyone cares:

Pre-post stacks
1700
1900
1600
1300 <--- Hero in SB
1500 <--- Villain in BB

FOLD EV = .1651
PUSH, No Call EV = .1809
PUSH, Win EV = .2906

Given Range: 22+,A6+,KT+
P(Call) = .1916, P(Nocall) = .8084
Equity of A2o vs. range = .36

Weighted Avg:
[ (8084)(.1809) + (1916)* [ (.36)(.2906) ] ] / 10000

PUSHev=.1662
FOLDev=.1651

Bah, no easy answer. Please holla if my math is off, I'm a dufus with numbers.

OP doesn't mention what buy-in level this is at, but at the low buy-ins, I hate pushing A2 (at least with this many BBs) because you can't trust that BB's calling range doesn't include any ace. Given that ICM seems to say the decision is essentially a wash with the specified calling range, I'd shade toward folding at lower buy-ins and maybe pushing at higher ones.

have you been stealing a lot from the button or SB? if you have been he may inclined to call out of spite ... if you havent been, he may lay down Ax out of fear

id raise to 300 almost everytime in this spot, fold to a reraise, and be very careful on the flop

Aren't A2o and K5o pretty much the same strength versus a random hand?
