Luck: I 2x barrel sometimes. Obv when a K or A hits I will but I also will double barrel low boards that shouldnt help villains in hopes that they may fold their 99 or TT on a 8 high board. Its def a spot I am not great at.

Micro: I've had everyone tell me that, that W$WSF is too low....thats why I try to 2x barrel more but it seems to get worse. I had started to really pay attention to the flops and I'm raising more when villain cbet me, esp if they are raising from MP and their range is a bit wider.

Daven: I dont iso much, not like I used to in 5nl. I dont find a lot of limpers it seems....steal more from the co? yeesh....sometimes thats where I feel my problem is...I raise, have my cbet called and I know I'm behind, so I have to c/f the turn

I 3bet more in the blinds b/c I will 3bet hands like 22-55, KQ and sometimes AQ whereas I feel I can call profitably on the BTN with KQ, AQ (vs a co raiser, not EP).

I 4x all early positions but I 3x the CO and I 3x on the BTn vs unknowns. If the blinds are known to fold lots to steals then I 2.5x

Your last point will take practice....
I spent a long time looking at HH and I was ok at ranges but yeah, no clue how to play against them...
