Villain= 21/17, 7% overall 3bet, 53% fold vs SB steal, 10% 3bet vs SB steal & 37% cold call vs SB steal. Villain fold flop-turn-river is 45/33/50 respectively.

^^ This is legit your average 25-50nl reg on party/stars & from stats we can see that villain is a tight aggressive player. Their 3bet% vs sb steals isn't high but isn't too low either, kind of a happy medium(could be higher), their defend vs sb steal is also in that medium range of 47% total & while it could be higher, it's still not in the realm where we're seeing instant profit or showing profit with low equity hands by opening them(if i'm wrong here let me know).

With our analysis here how do we play in the sb, what range do we open & how do we defend vs 3bets? Do we take an exploitative approach of opening 50%+ in the sb & overfold to 3bets as villain isn't 3betting an amount which is exploiting us? do we play 50+% of hands & try to defend vs 3bets with 20+% of hands oop? do we lessen our sb steal range so we're not exploitable vs 3bets or do we implement a limping strategy?

Would like to hear some thoughts, as really this is the mean of the 25-50nl player pool on zoom & the 25nl player pool on party fast forward.

UPPP

Yes some 60-70% open and can slightly overfold to 3b. Do not see reason for limp, 52% is nice fold equity, take the advantage of FE against only 10% 3b.

Agree with shamway although I'd lean a little closer to the 60% side than 70. I think playing a tiny bit safer against this type is better in the long run to keep you out of trouble. But I"ll also add that a 10% 3bet is still relatively wide an occasional 4bet semibluff is not out of the question. He will start exploiting you if you fold to all his 3bets.

This must be a 6-max game, correct? 21 VPIP is certainly not tight full ring. Also, we're SB- are we facing a raise from villain? And if we are, what position is he in?

There are separate forums for 6m and full ring. This is the 6-max forum. We're button.

I'm sorry, OP. I got nothing. I play against monkeys and robots.

Sorry, but I don't see how to differentiate between telling that this is a 6-max forum vs. a full ring?

Are you saying the villain is button? Cause OP's question states that we are SB.

Hmm I'm not seeing it? I'll do some more searching and probably find out how to separate uNL forums by 6-max and full ring.

Haha that makes two of us

villain's bb and we're sb. I think that's obvious from OP's post...after reading it 16 times. As you can see above, I deleted my post because I was so flustered. ****

This makes my head explode. Open a lot of hands. Fold to 3-bets unless you have reason to believe that a villain is majorly exploiting you. If they are exploiting you, open less hands so you can defend more often vs. 3-bets which, in turn, exploits his exploit. Don't want to open less hands? 4-bet more semi bluffs and be willing to get in lighter. If you were getting in with A8s, get in with A6s now! Limp sometimes (gasp!).

IMO the question was on SB position when folded to us. definitely would not recommend to open 60% on btn nor defend so wide on SB.

If you're opening 60% in the sb, what constitutes a slight overfold? i mean how much hands can we even defend comfortably & how does such a range look like?

Personaly I defend about the same range as BTN vs blind 3b, the same way (4b,call,fold). Because my btN open is about 40% defending the same on SB means overfold.
My arguments for overfold to 3b on SB are players dont defend BB enough and dont 3b enough. Ofc you can build more balanced defense to 3b on SB if you wish.
