There is no reason i should'nt be crushing 2nl.
I suffer from this kind of arrogance, and it's taken me quite a lot longer than I'd have hoped to realise I'm wrong. And so are you.

Just because you post in a poker forum, try to play good poker, and you're playing against muppets, doesn't mean you should be crushing it. It's easy to think we can outplay fish on every street, and that mindset encourages mistakes that hurt our winrate to the point that we're no better than the field.

What sets out the good players from the fish at these stakes are hands like this. If you fold 99 pre flop when facing a 3b and 4b, you just did something that 90% of the field is not doing. That's what makes you a winning player.

Be disciplined.
