I am watching a lot of video on this site, i would like to say thank you to pros for all this great stuff you trying to share with us.

Anyway, around 25 min of part 2 , bigdog (UTG+1)  3bets JTs  when UTG minraise. I think theyre are somewhere like 50 bb deep eff. He doesnt explain why 3beting here is better than flatting and i cant find argument which goes in that way.

I always think that flat>3bet in those spot when you have hands that playing so well postflops and when you have position.

Please, tell me your ideas about this hands

bigdog if you see this, feel free to explain me your thought process it will be very cool.

PS: Sorry for my english im french.
