I too am a limit only player. As you and everyone knows the game changed a couple of years back. The competition increased exponentially. I had a hard time adjusting so I just kept playing till

a modest bankroll was gone. I had to drop to lower limits but still the game wasn't the same........Only recently has it dawned on me(duh)........my opponents are literally playing everything.

I don't know if this is the case in your limit range but it's amazing the difference it makes when playing against the same players. (goddamn Russians).

I'm still more prone to fold pre-flop with a weak hand but now when I'm in it takes a lot to get me off it. It's more a game of chicken now. Would you agree?
