hello
-im interesting in talk about our range in BB wen we faced a 4b vs BU .
-this is an especific range but, if we have better idea of how cc4b in this situation we can cover alot of another situation in blinds war.
- obviously vs alot of people we can used a explotative 3b , and no used a pretty GTO strategy, but i want to study this becouse if i 3b to much i can be explotable if i fold alot to 4b.
- im not saying this is the best range for 3b , but if u 3b this ,what is the better defend ?
this is the LemOn36's range to 3b here

im going to change somethings im think this is my range :
Where light blue is a call, red=always 3bet, orange=mixed strategy ("bluff" sometimes 3b or call or fold) , blue=always 3b.
this is my 3b range

i make some changes:
- 33 and 22 now in a 3b range
- A5s- A2s is 50% callin 50% folding
- and the other bads suited blufs 50% fold 50% 3b
-75s and 64s always 3b , are too stronge and good to defend vs 4b ( this is part of discussion )
counting hands :
we have a 298 3b hands
counting 4b bluff equity :
if bu OR 2bb and we 3b 7bb and he 4b 17bb , his bluff equity are :
15/(17+7+0.5)= 61 %, we have to fold less than it .
if we fold 57% for example we have to defend by raising o callin 43% of our 3b range :
298*0,43 = 128 hands
my question is wich 128 hands ? ?
i'm think this is what i used:

red to 5b , green mixed 5b and call ,yellow allways call, TT and 99 always call too (mistake)
lemOn36 prefer suited brodways to call 4b , i call all AQ and Ajs KQs but is to hard to me call like ATs JQs Kts, becouse this hands are pretty dominated.. then i used to call suited conectors .... is there in your mind any argument that makes me change my plan ?
