What kind of factors probably support the profitability of wider opening ranges?
Ranges proposed by a solver are based on perfect play from all parties, while we play poker in a setting where no one is playing perfectly (and maybe, at a given table, no one is even playing well).
But there have been a number of players on this site and elsewhere that open with much, much wider ranges with a lot of success. I’m not particularly LAGgy on the LAG ( Loose Aggressive) spectrum, and mostly consider myself a TAG ( Tight Aggressive) player, mostly only raising pre-flop with hands that I feel will have good equity and good equity realization given my position and the number of players left to act.
