Q6o vs half potsize donk bet on flop and turn

impossible to know without info. it seems fine, raise/folding also.

so you need to look at past hands that got to showdown to know what he can have ( perfect information)

you look also at the frequency he does it ( the higher the more air probably)

and this is a nice tip, look at his fold to cbet, thing is he cant have hands everytime he checks and everytime he donks, so if he isnt folding when he is checking probably he has his made hands theire, and his donks are weaker. and vice versa

theire you conclude that he has a air weighted range or a strong range or a capped range. and you play acordingly

extra: also dont forget pre flop, if he´s folding tons its just hard for him to have a lot of air

so vs capped range its a must raise

vs strong range just flat

vs weak range you can slowplay a ton of hands in position since he will fold to raises, but here your to vulnerable so just raise to protect vs draws.

Hello,

felipe summed it up quite nicely.
