Hi,

Let's say for each street I use 3 categories of bet sizing for my range : small/medium/big.

So this allows me to dispatch both my value and bluff combos in these 3 categories.

For the Flop and Turn, I think that makes sense to adjust these 3 sizings depending on various factors.
For example, on Turn, each one of the small/medium/big sizings would be bigger if the board is drawy than if the board is super dry. If the board is Tc9c5d2d, my small/medium/big sizings might be 70%/100%/135% of the pot, whereas if the board was 7c2d2h5s, it might be 30%/55%/95% of the pot.

I think that makes sense, right?

No my question : can we have the same approach on the river?
If so, which factors could allow us to determine if a river spot should generally be bet big or small?

Although my ideas are pretty clear about Flops and Turns, it's quite hard for me to adapt this concept to the River spots.
