As a bonus here's a bit of info about the small bet with your range thing. Let's take the classic A72r board for this. Are we betting range with a small sizing on this kind of board? And if so, why? Again let's look at the equity graph.
So what we see here is that BB is actually pushing 70%+ equity quite deep into it's range. About 17% of it. This is all top pair+, however once we move out of that region BB's equity drops off a cliff. The rest of it's range has 50% or less equity. You can see that compared to the other graphs, the gap between the middle portion of the 2 lines is huge.
So what we can gather from this is that
1. We can't put in too many big bets with high frequency because BB has a lot of top pairs with great equity
2. We have a huge advantage in the middle portion of the range and we would like to leverage this somehow
These two factors together lead to:
