Example as 3bet OPP:
CO opens 2.5bb
SB (Hero) 3bets 9.5bb Ad2d
BB folds

Pot 20bb
Flop comes Jd5h8d
Hero checks - CO Bets 8~14bb - Hero raises 24~35bb

Is this a decent line at 100bb no reads?

Example at BB call:
HiJack opens 2.5bb
others fold
BB (Hero) completes with Ad3d

Pot 5,5 bb
Flop comes Jd5h8d

At this pot size, isn't it better to check-call flop -> check-raise turn or if checked behind at turn, bet river ?

I mean, at first hand we would get more fold equity / still have decent equity when going broke at flop, but on the smaller pots, we would get more money by letting our opponent bet flop, bet turn, bet river
- Does this assumption make sense in reality ?
