I can't beat 100NL

i'd suggest adjusting your playing style slightly

but what do i know?

btw are you playing FR or 6H?

small sample

-11 buy ins over 28,5K hands at low stakes is a big enough sample to know that at best ure edge is very small to almost non existant
more likley u get owned.

look at your loosing hands and think of strategies to adjust your playstyle
If they 3 bet light , start 4 betting them
or tighten up our raising range at positions ppl 3 bet u light.

f.e if u always get 3 bet when u open from MP but people tend to give u more respect when raising from UTG ->
tigthen up ure MP raise and maybe open upt ure UTG range a bit to a ploarized range ( low SC like 45s and stuff)

If they squeeze a lot in obvious squeeze spots just 4bet or shove them

Poker is all about adapting.
U either must increase ure agression
or tighten up your hand range when facing agression

10bi over 26k hands not a good sign at 100nl. breaking even over that sample is bad enough. FR or 6max?

i play FR
