Just because you are in a casino playing higher stakes than you would online, doesn't mean the players are better. You are probably still playing the lowest stakes possible and people go to casinos
So when I go to AC and play in a $100 tourney, the players are equivalent to a $2 tourney online. So naturally they will LIMP, LIMP, LIMP, CALL, CALL, CALL.
Easy example...blinds are 50/100, I'm in middle position with AA, I raised to 600, got 3 more callers. Flop was J 8 x rainbow. I bet about the pot, someone min-raised me, other 2 fold, I shoved. He insta-called with...Q 10. Fortunately he missed his straight.
