I'm misunderstanding the concept, and am looking for help. From my understanding, and from Lefort's vids, we need to defend at a certain minimum frequency to prevent our opponent from auto profiting. We choose to usually defend wider than minimum because at around the minimum frequency, our opponent isn't auto profiting with the very bottom of his range, and we have equity in the hand. Essentially, this is why vs a minr HU, we choose to defend much wider than the 1-A min def of 50%.

It'll be easier to post a specific HH I had in mind.

100bb stacks, HU.

We minr Td9s, BB 3b 9x, we call.

9d 4s 4h flop, BB half pots, we call.

I have our range at ~38%-8%, and plugged this range into PPT. We have roughly 365 hands. BB cbet's half pot (1-A=.66), and we call.  We should defend at least .66*365=243 hands that call the flop. I deleted the hands with the lowest equity until I reached 243 hands. 

6c turn, BB half pots, we call.

1-A again is .66, and we are looking to call 243*.66=162 at the minimum. Repeat process for the flop. 

2c river, BB jams, we call. 1-A is .527, and we need to call .527*162=~85 hands. I'm failry certain PPT removes combos with the board input, and our finaly minDEF range of 85hands: Ax9x,Ax4x,Ax9y,Kx9x,Kx4x,Kx9y,Qx9x,Qx4x,Qx9y,Jx9x,Jx9y,Tx9y,Tx9x,9x8x,9x7x,88,66,44,22.

This was 100% of our 9x we had from our preflop range, all 4x, and all quads/FHs, as well at our 88 combos. Now, what does this all really mean? What can we derive from this?

On the river, it is 322.5 into a pot of 360, and we need to be good ~31% of the time. I went from BB range and started plugging in hands and running equity, until SB had ~31% equity. BB range looked like: AA-99,Ax4x,Kx9x,8x7x,8x6x,7x5x,7x4x,66,6x4x,5x4x,4x3x and was based off a 22% 3b range. I took out some J9s strength hands from a river jamming range, and left a few bluffs in.

Since we know what SB has to defend with, what do we want to do from BBs standpoint? We just bet anything with over 50% equity? If SB isn't defending enough (maybe SB is raising some trips or something earlier in the hand), then as BB we should be firing the river a ton? 

Is there an easier way to do this analysis in PPT or CREV?

This is mainly for readless players, or the one really good player at the table where I'm not making any $ from. I'm butchering a bunch of concepts at once, so hopefully someone can straighten me out.
