This hand is ugly right from the get-go,
CO limp/calls AI w/20%(he only buys-in for 20bb)
BU= unknown(opened utg and folded to 3b)
BB=super nit reg
utg=28/11fish over 110hands, he's not doing anything fancy utg , when he does limp/raise he's basically a station. only fold2cb' 2/9 , 7/9 he's just calling..

call Fl'?
