Dear Matthew Janda
I bought the book 6months ago and i’ve found it excellent.
I am currently rereading it with deeper questioning.
I’ve got a lot of questions in mind.
On page 41-42 you analyse the maximum 3betting ranges vs opening positions.
I have understood the process thinking and tried by my own with different opening sizing.
So as you explained I consider we must multiply the odds each player doesn’t 3bet the open together. For each open sizing I have taken in account the frequency of defence against the open to prevent the opener to show an automatic profit.

1st question :
Do we assume with this calculation that the defense vs an open is equally shared by the players around the table ?
For instance When UTG open 3BB each player can 3bet at maximum 8%. Would be more realistic to consider HJ needs to defend less than CO and co less than OTB and so until the Big blind? Would he’d be likely to build such a function? I assume the total defending frequency against the open would show an average of 8% by player in that case but the HJ 3betting frequency would be more like 5%, OTb like 8% and Big blind 12%?
2nd question
Could we use this calculation method against a 3bet in order to define at which maximum frequency each player can 4bet (assuming than cold 4betting is possible) ?. We would consider the fact that the defence against a 3bettor would be shared by all the players if I understood correctly the concept.
For instance HJ 3bet vs UTG open. So the defence against the HJ 3bet should be around 30% total to prevent him from showing an automatic profit. I used the same logic than previously by multiplying the odds each player doesn’t 4bet the 3bet together to find answers.
I did the following calculation for an open size of 2BB.

We find if HJ 3bet 8 BB against a 2BB open of UTG, so each player should 4bet 7% maximum. Does it make sense ?
Thank you for your consideration and your help
I apologize for any language mistakes knowing the fact English is not my native language :-)
I look forward to hearing from you soon,
