1) don't push nash from early positions (push tighter)! (6+ plrs left)
i think thats sth that helped me the most when i was climbing my way out of the micros. When i came across the Nash Equilibrium, started to spend a lot of the time with the ICM Trainer and Nash Calculator and was like "now im indestructible, cause i 'know' nash and all those fishes dont"
it took me quite some time to really understand how big of a difference to my pushing range it makes if they call waaay wider than nash.
2) 10bb effective in HU you can profitably push 87,3% (22+, all suited hands, J3o+ T4o+ 95o+ 84o+ 74o+ 63o+ 53o+ 43o) if your opponent calls 30,6% (22+ A2+ K4s+ K8o+ Q9s+ QTo+ JTs).
I'd say thats a reasonable calling range for an average unknown. Maybe even a bit tighter and then we can push ATC. Nash pushing range for 10bb is 56,6% so if youre pushing nash youre missing out on a lot of value. Works best with high blinds/similar stacks. If its let's say 200/400 level with the stacks of 16000 and 4000 (Party structure) they tend to call looser cause i guess "this tourney is already over whatever I do"
