so you raise to limit your loss when behind and to stop a bluff on the river that you feel it would be -ev to call. you might also get some more money out of a weaker made hand this way if we assume he will not vbet river with a worse hand and you will be tempted to take the free showdown. you also make a draw put in more money as a dog which makes you money even though it is right for him to call. is this correct?

you lose some when he is on a semibluff and would have bluffed a blank river for more than 100. you save some when he would have vbet a better hand then yours on a blank river. or if you would have folded to a bluff on the river you now win the pot + 100 instead.

if you thought you could play the river better than him then a call looks better I think. the problem ofc is that any K,Q,J,9,7 is going to make it difficult to make the right decision esp since you only have a few hands on villain and can't know how he will react to different river cards.

you could raise more to make it incorrect for him to call with a draw. the problem is that if he calls anyway it will only be a small mistake but if he has you beat it will have been a big mistake on your part.

If your raise won't make him slowdown with a worse hand then obv it's no good but if you think he will make it easy for you then i can't really see anything wrong with it.
