Hi guys! I'm trying to improve my blind vs blind play and one topic that I don't see often on videos is calling 3bets OOP.

If I'm opening 60% from SB theoretically I should defend 33% of that range against 3bets so that my opponent can't auto profit. That means against a 3bet I should continue with a 20%. If I 4bet 99+, AQ+ for value that's a 5%, so I can add another 5% of 4bet bluffs. So what happens with the other 10% I should defend? Does it make sense to start calling 3bets OOP with something like 66-88, 87s+, suited broaways, AT, AJ, A9? And asuming that is right, I still have no idea how I'm supposed to play that range postflop.

Even if that is a theoretically correct defense range on practice I have a huge trouble applying it; I play NL50 FR and against many opponents I don't feel comfortable 4bet/calling something like TT/99 (some people don't 3bet much or fold a TON vs 4bets). And once I call their 3bet I end up folding too much postflop because I find it very hard to play 3bet pots oop without initiative. However I think it's necessary to call 3bets with those hands because if I start 4bet bluffing them, my 4bet range would be extremely unbalanced.

To sum up my questions are:

- Against someone who doesn't have any evident leaks, is my 4bet value range reasonable? And should I be calling 3bets with the range I mentioned?

- For those of you who know NL50/NL100 FR dynamics, do you think my ranges make sense?

Thanks!
