Hi ho. I haven't been playing for two years (kids etc.) but now I'm back. I might be a bit rusty so I''m gonna need your help. Firstly... a friend of mine said the games have changed and advised me to start lower than I used to play. So how exactly have the games changed?

Also I want to check my pf opening ranges. i play 5max at boss.

UTG: Axs, 22+, ATo+, QJo+, 56s+, KTs
CO: A8+ , KTo+, QTs, 68s+
BTN: ATC depending how loose the blinds are and how much they fold to cbets.

Mostly I'm comfortable with the ranges but not sure if i'm tight enough from utg.
