the spot is: CO (weaker playe) open limpls
BTN (regular) isolates him w\ pot size raise
SB (hero) has AhKsJd7s

all have 100bbs stacks

BTN iso vs 1 limper is 28%. PJ allows us to put FI25% (closest number we can get),
so vs 25% first in range we have 49% equity.
let's say BTN is standard reg, not really aggro, fold ~50% vs cbet in 3b pot, and there is a chance that CO will overcall our 3b.

fold?call?or 3b?
what if BTN isolates 40% in this spot?
