I think the title of the thread is generally true, but it seems like an error in evaluating cause and effect.
cause: the bettor has many strong hands and many low equity bluffs, while we have many weak hands and few strong hands.
effect: we rarely raise.
As Arty points out, the bet size plays an important role here:
Quote:
Vs a pot-sized c-bet (with a very polarised range and fairly low frequency), it only check-raises 0.2% (effectively it doesn't have a raising range, and prefers to call with 44/A4 etc). If SB only c-bets half pot (less polarized, and at a higher frequency), then Snowie thinks the BB should check-raise over 15%.
cause: A smaller betsize allows the bettor to go for thinner value and reduces potential bluffing frequencies.
effect: we raise much more often.
