I was thinking about this topic yesterday while thinking about my x/r range on a certain texture BB vs BU. What should be a good bluff to value ratio to have in your raising ranges OTF and OTT? I guess this should depend a lot on board texture, but in general (and without specifc reads of villain tendencies) what number should we looking for? Some ideas I think are worth considering:
1) Flop and turn are different from river since our bluffs still have equity vs villain's bluffcatchers and villain's bluffcatchers still have equity vs our value range. How should that change the ratio?
2) In some textures, the turn/river card might change drastically how the equities are distributed. How should that affect our ratio?

Are there any videos that talk about this?
