lets say 40bb deep, btn raises and sb 3bet linear range and btn flat.... flop AJ8cc, in cash games, it seems more standard to check hands like A3s or QQ,KK (especially with a club), KJs, QJs... in tournaments, ppl seem to cbet these hands and divide their range on the turn. what is the merit of this and how do ppl divide their turn ranges in a balanced manner?
