a) How to find out how much particular villain 3bets me in particular. E.g., I think some of them 3bet like 5% but vs. me 3bet like 15% as I fold too much. How to confirm this?
b) How to find out what my winrate is vs. regs. E.g., winrate vs. everyone I've played more than 5k hands with and whose VPIP is below 28% or smth like that.
