I could try and impress people by making a really long post. It could contain alot of fancy concepts, language or a detail mathematical breakdown.
But once you get beyond the holy trinity and value-betting - I believe there is really only two things you need to do to beat uNL.
1. Play vs weak opponents
2. Play vs weak ranges.
Preferably both.
1. What is most often confused in this forum, is what constitutes a weak player. Given alot of 2+2ers use statistics and HUD - they often equate a statistical range of VPIP/PFR with weakness. However it really only is a clue as to exploitable tendencies. Here are some useful sign posts for actual weaknesses.
(a) limp/calls OOP & folds flop
(b) calls 3-bets OOP & folds flop
(c) donks flop and folds to raises HU
(d) PFR and doesnt c-bet A or K high dry boards.
Have a note that = to each of these and you have a goldmine. If villian who holds any of these continues past the flop - please have a nut-type hand before putting in any more money.
2. Play vs Weak ranges.
What do I mean here?
(a) limpers - it is compulsory vs 1 limper to raise as much(often) as humanly possible from CO/BTN - the only times you should strengthen your range is when there is a solid player in either of the blinds who likes 3-betting - Iso raises... or a history of limp reraises.
(b) either call or 3-bet any open from CO/BTN with most of your steal range.
Which of the two should fit with how well the holding plays in 3-bet pots.
(c) If you would raise from SB you should call a raise from BB. With the exception being from extremely tight players with the bottom of your SB blind stealing range.
(d) Whenever possible you should avoid playing OOP as 3-bettor even vs weak ranges...
Obviously if you have both it is ideal.
You should be inclined as PFR to be C-betting almost every board if any of the above of 1 and 2.
You should reassess villians weakness past the flop. If villian has called your aggression PF and on the flop particularly OOP - it is safe to reassess villian as no longer weak and usually has a 30% equity draw at worst.
If you focus on weak players and weak ranges - you will find that you will rarely be bluffed, you will win alot more hands without showdown. You will likely improve your winrate as well as generate a table image that will get you paid off more by regulars.
Sorry no blindingly new insights.
But your inner mantra should hummmmmmmmm weak players, weak ranges.
That is all..... I got.
