Lets say in a HUNL game, sb raises pre and bb flat calls.
Flop comes A74r. sb chooses to cbet pot with strong Ax or better, and some bluffs like 56, and checks the rest.
What should be bb's response with his very strong holdings (2 pairs & sets)?
It is commonly said that we should not raise them on a dry board like this to keep our range uncapped. However, as far as I know, solver does have a raising range, which would include most of the 2 pairs, balanced with straight draw and some back door stuff. Are there reasons we should be deviating from what the solver suggests? or are we just doing it wrong?

It's something human players like to do for simplicity, but not something that is optimal.

Extra strategic options will never lead to -ev. Only 0ev or +ev. So limiting your strategic options is never a correct move. As you said solvers don't care about how unfavorable the board and ranges are, they will always have a raising range as long as they have hands that benefit from being raised.

I don't know what the equilibrium solvers produce as results for this spot, and I know very little about HU, but I found it interesting to run the spot in Snowie.

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%.

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:

cause: A smaller betsize allows the bettor to go for thinner value and reduces potential bluffing frequencies.

effect: we raise much more often.

Also note that as the betsize increases, the strength of the bettor's range increases, the effect is that slowplaying goes up in value. Thus the lack of a raising range.
