Pre Flop: (pot: 2.38 BB) Hero has A 3

fold, fold, fold, CO raises to 2 BB, Hero ?

CO is pretty decent player, and aggressive in stealing from late position. (15 times out of 21, 71.43% total 91 hands only)

assume CO open with
22+,A2+,K3s+,K6o+,Q8+,J8s+,J9o+,T8s+,97s+,86s+,75s+,65s,54s (40.27%)
and call with
55+,A7s+,A8o+,KTs+,KQo (13.88%)

(16.7%) 22+,A2s+,A9o+,KTs+,KQo,QTs+,JTs is our pushing range. A3o is -0.05%

Assume
SB overcall is 99+,AK （3.8%）
BB overcall is 99+,AJs+,AQo+ (5.4%)

I think CO could be open more than 40.27%, making this decision a little bit closer.  What do you guys think?

The ICM is calculated with ICMizer 2, I think FGS (Future Game Simulation) is not needed here, as no stack is lower than 10bbs, and CO and me are not in UTG, SB, BB next hand.
