I would actually shove this turn. Pretty hard for it to have helped his hand, and certainly improves your range from his POV. A Shove looks so strong here, i cant do EV calcs, (just tried and got confused lol)
give it a go, post it and ask if its correct... [best way to learn]
as a quick rough estimate, with a possible 10 outs versus a range of say TT for a set , 99 and JJ equity wise AK would be around the 17% area + or - a percent.. if jamming the turn and u think villain will fold 15 to 20% ish of the time then u will break even EV wise.. some1 give the EV calc a bash, as a base guide the pot is 127 and 88 behind -> 88/215=41% so u"d want 41 folds to break even if u have no outs whatsoever...
all on reads, as the villain isolated 2 limpers his flop calling a 3bet range would be likely TT+ and maybe a % of air with over-cards which he might float with [but we have no reads to make that assumption]
u could maybe with reads say he isolated with 99 maybe 88, AT met be a likely candidate in villains isolation range, but to calll a 3bet? hell if i know
all on reads, its hard to guess what he has based on hardly no info, jamming the turn is a option but not a wildly profitable one given the lack of knowledge imo... if u were playing these opponents on a regular basis then g-bucks wise by giving our hand a perceived range and comparing it to our opponents range, u could look at this completely differently in the long term, but at this level though do u need to play like that to make money?
