Hi guys, I'm playing HU NL100 zoom and I'm beating it at a good rate since most people have severe gto deviations. Despite that I'm not a veteran, pro for 2 yrs, HU for 4 months, possibly around 150k hands. Last night for the first time since I'm playing HU I had to make a heavy preflop adjustment and it's fair to say I didn't know what I was doing. Im rarely put in a tough decision in these stakes but this guy who was tagged as a good reg from my 6max days, 3b me 65% of the time. Obviously open folding a large amount of hands is a disaster, so I started tightening, going 4bb then min 4b or straight jamming, or I limp call/limp reraised. Although I took the biggest pots and won 2 or 3 buyins from him cause he has other leaks, game had such a dynamic that it took me to a tree I don't know how to play. What would be a go to strat of 4bb/limp call/limp reraise vs such an opponent because I saw other people doing it too but were way too recreational to think that deeply. What hands go where in such a dynamic. This may not be the optimal solution and I'm open to other adjustments. But as a start lets think about
What hands open to 4bb then jam?
What hands open and min raise?
Which is better? Why and how to adjust?
What trash classes or percentages opens to 4bb and fold? Do I even have to polarize here or go linear only the hands that dont fold to 3b anyway?
What hands limp call?
What hands limp reraise value?
What hands limp reraise bluff?
What hands limp fold?
Do I limp fold any? How wide can I go to with limping without info about his iso range?
Any other things I don't see?
This is so far from gto that I'm lost.
