Thank you for posting
The standard ratio for value/bluff on the river is 66%/34%
Nits play a tighter range and often payoff on rivers with top pair or over pair so we would bluff less as we can make more from our value hands than our bluff hands.
If you are playing against (Nits)-Tight range weak player that fold top pair on river we increase our bluffs on the river to 80/20 easily often only having to bet small river sizing to get that fold. This was a common player type -it is not so common anymore so we need to experiment to see how weak the table is.
Nits who are weak tight often fold 2nd pair or worse -weak draw- over cards etc on turn so our bluffing strategy for these players is an increased bluff % on turns not rivers.
We would small bet flop- small relative to the players at the table- some players think half pot is small- then we can bet 75%-1.2x pot turn again dependent on reactions of villain type
Hope this helps
