well, put it that way, it's 2 dollars per week. If you feel that chess.com as a chess club is worth 2 dollars a week, pay it. If you don't, don't. You can even play here for free, and that's certainly no scam.
you mean 2~ a day?
Does a year last ~50 days?
Chess.com is great, apart from how easy it is to install add-ons for cheating, almost 70-80% I played with are using those cheats, with insane champ moves in last 20sec...... you'll be surprised.
Chess.com needs to improve security and restrictions on browser level like every other online quiz website got, that you can't even right click or move away from the window, add-ons shouldn't be allowed on the window etc. so we'll get rid of these cheat hackers for good.
Chess.com, pl up the game, it's so freaking easy to cheat on here.
70-80% is not a realistic estimation of cheaters and your intuition is not good enough to identify one, definitely not based on a move or two.
