higher limits

why is higher limits a harder game? i mean we are all playing teh same game, and i watch some HIGH limit stuff from time to time and i still see the same crap winning

Higher limits does not mean it's a tougher game. However, good players that win consistently build large bankrolls, and those bankrolls allow them to sit at big buy-in games. Therefore, good players that win consistently are more common at higher stakes games than beginners.

... and that's what makes them tougher, on average.
