MATH : Issue while creating 3/5 bet ranges
i m working on my preflop game and i got a problem,
When i create ranges that cant be exploitable in regard of betsizing it does not take in account opponent range, so finally i feel it s not usefull
exemple
i have a 3bet range 7.2% i want a 5 bet range so that oppoent can not 4bet me and win money
effectiv stacks 100bb
blindes 1.5bb
he opens to 3bb
we 3bet to 9bb
he 4 bets to 23bb
vs a 4 bet our defense will be a 5 bet
minimum defensive frequency vs 4bet :1-A where A=R/(R+1) where R = his bet / pot size
here his bet = 20, pot=13.5 so MDF = 40.3%
so i have to 5bet 40.3% of my 3bet range to avoid being exploited
because we 3bet 7.2% we need to 5bet 2.9% which could be JJ+,AKs,AKo
(if we 3bet 9% we need to 5bet 3.6% which could be TT+,AKs,AKo)
thats seems great BUT
**if he only 4bet AA i will lose money wiht my 5bet range, even if i did math that i have to defend this % !!!
**given different call 5bet ranges we have different equity with different 5 bet ranges and that math does not take it into accoutn !
i m not sure to be clear but if i sum up
i want to work my ranges with math
i dont understand when we speak of GTO we only speak of besizing (minimu defensive frequency) and we dont take range in account
so in my exemple is these ranges really good becasue not exploitable? 3 bet 7.2% / 5 bet 4.3%?
thanks for your help because i took the most basic exemple but i also want to do it with 4bet% and 3 bet %
have a nice day

i mean we have his 1st open stats but that does not say what he 4bet bluffs and 4bet call
if opponent opens decent range and only 4Bs AA you should use exploitative 3B plan - ie if he is never calling 3B bluff him tons and flat your good hands - of course this extreme never happens in game but the point is when opponent is playing in a way we can easily exploit we should deviate from a "GTO game plan"
overall keep in mind that any GTO range is just our best estimate because we don't know opponents exact RFI and their exact range construction
really like this forum!
have a nice day
Since opponents are different you adjust ranges accordingly, if they 4 bet AA only you 4 bet them to death but as Mike said its very unlikely, so versus such opponent you widen 4 bet range and 5 bet call or make 5 bet only very tight range AA KK only ( not even kk if you are sure he 5 bets AA only, tho i cant see any player doing only AA 5 bet but hypothetically )
Against player who is playing wider 4 bet range and correct 5 bet range unexploitable according to GTO you play according to maths, but you cant make a fixed 4 bet 5 bet range or you would be exploitable i suggest you take it as an approximate and tune it depending the opponent and situation
I don´t understand that sentence. If we play a fixed GTO-4/5-bet-range, we´re unexploitable by definition. It might be that we don´t play for maximal EV, but we definitely are not exploitable. Even if we 4b/call KK, "knowing" that Villain only shoves AA, he doesn´t exploit our overall-range because he´s folding too often to our 4-bet.
Thats not true. GTO is a play that makes money no matter what your opponent does. (doesn't mean it is maxEV of course)
But not playing "maximum EV" does not mean that we´re exploitable either. Being exploitable means that Villain can maximize his EV by deviating from GTO himself. That is not given - by definition - if we play GTO, because then his maximum EV comes from playing exactly GTO himself. Hope that got clear.
Now, say we´re betting our 10 nut-combos and 5 bluff-combos. Now we play GTO. Villain can do whatever he wants, he can always call, never call or throw a dice and decide if to call. If he never calls, we win $100 in 15/100 (for an average of $15/hand), if he always calls, we win $200 in 10 times and lose $100 in 5 times for a total of $1.500 over 100 hands, which again makes $15/hand. If he does anything in between we still win $15/hand. => Villain can do whatever he wants, we win exactly $15 per hand. This is GTO.
Now, if we knew (!) that Villain never calls - our adjustment would be easy - we would bluff 100%, so we don´t win the pot 15/100 times but 100/100 times. Obviously the result exceeds our GTO-approach by far, but now WE are exploitable ourselves (Villain just had to start calling 100% and would print money himself).
You see, playing GTO is not exploitable. In contrast - we have to play exploitable ourselves to exploit our opponent´s non-optimal tendencies. And we can do that (hopefully) - because Villain does not recognize that we got exploitable while we take his money.
if i undestood well my 3/5 bet constructions only helps me when vilain ajust ot my 3 bet exploitative mod
then i go to my 3/5 GTO mod to be sure he does not exploit me with his 4bets
thanks
are you using CREV to make calculations on your ranges? If so, please share in detail
i only take a GTO approach to other good regs who are already balanced but vs weaker players a good exploitative strategy will make you a lot more money :)
