When to overfold your range

qjcc-pf-3b

Preflop:
I will give my opponent a 15% 3b range.

Flop:
I think a lot of regs will cb this flop a lot, so lets say he CB 100% of his range here.

Turn:
I will let him barrel with KQ+ and any FD and GS.

River
I guess his value range is KK+. This are 40 combo’s. We get around 33% pot odds, this means we he should bet river with 20 combos of worse hands.

Potential bluffs
45s = 1.2 combo
AQ= 12 combmos
AdKo= 3
AxKd=3

Even if our opponent bets with 100% of his potential worse hands its not even a call. Looks like a spot where we can overfold our range.
