there have been many moments in 2+2/training video history when i thought "great, now the games are ruined." but i still make money consistently, and i'm no poker genius. there was Fees' 6max free pdf, Spamz HHs, Mers ST videos, and so on. i cringed when i read that a free book is coming out in the low edge world of STs, especially since i play on regsville merge. but in the end these freebies always help me make more money, but maybe if i played higher stakes that wouldn't be the case, i dunno.
i'm not sure why it is that fish regs don't get a whole lot better with this stuff. i mean yeah games are always getting tougher but i seem to stay ahead of fish regs, and i'm no great theorist. maybe it's a lack of experience. having played 500 hundred gazillion billion games makes me more comfortable and less spazzy and more adaptive i think. so someone with 3,000 games under their belt with lots of free 2+2 theory crammed in their brain might get overloaded and misapply stuff in-game.
maybe another thing is fish regs don't do their own homework. there's a lot of stuff not in books that needs to be worked out mathematically. there's no time in-game to do them because of different ranges and stack sizes. i've done a good bit on my own, maybe enough that it keeps me one step ahead of fish regs.
also tilt issues are a biggie.
another is maybe i'm enjoying remarkably long-term good variance against them
