I'm "new" to online poker, with about 15k hands so far. My cumulative stats are VPIP 30, PFR 15, 3B 7, FT3B 63, AttSt 31, FtStl 63.... obviously WAY TOO LOOSE PASSIVE! I play 10NL and 25NL.
I assume that this is inclusive of all table sizes with the exception of heads up.
I feel that my opponents have been exploiting me by opening wider and 3betting lighter. I also feel that my play has drastically changed over the months that I have been playing. I started out at 25NL and I think that's where I really donked it up. So I took a step back to 10NL and did some studying. Now that I've stepped back up to 25NL, all the regulars have those terrible stats on me.
Should I just start a new account with a new screen name? Or should I just tighten up/adjust to opponents exploits?
While you have 15k hands on yourself, the odds are your opponents don't have very many hands on you. If you only have 30 hands on a villain, they only have 30 hands on you. They don't know what stats you had in the past.
FWIW, we all asked dumb questions to start on 2+2. Welcome to the club.
