Ok thanks, most of this I understand, the pot to bet ratio for hitting a draw for example.
But how do you turn this around?
For example if you decide to bluff the river with a shove, doesn't that change those "ratios" completely?
How do you calculate how often it will be profitable?
Is that really all there is to it? Looking at the ratios?
(sorry if my choice of words is bad, noob here)
