Can an abc predictable preflop player beat 100-200?

[fishboy]

I've been haivng a discussion with different people lately about whether a abc predictable preflop player can beat higher games. Can someone playing very tight solid poker beat higher games? Or do they have to mix it up? And if have to mix it up in what way do you need to mix it up to vere from solid pro play?

If a player plays solid and doeswn't make mistakes how can he not beat any game? I understand that hourly rate might be better if he made some plays sometimes but wouldnt he still win? And when making plays isn't it to create an illusion of gambling and to actually play solid poker? It almost sounds like people think you can't play solid poker and beat higher games. That you need to be getting out htere doing unorthodox things all the time?

So what do you guys think does solid abc take the money or will he lose?
