"I have a big hand and pot odds. I fold"

[sunrise]

I think there is a lot of irrelevance with reference to the pro's. Pro's are def. going to play different against Pro's vs amateurs or unknowns. The 2+2'er's are most likely going to play differently against unknowns vs other 2+2'ers or other known online players.

I agree that it is still a math play against an unknown. Course once you've developed a read on someone in a specific tourney, even if you've never played them before, do they become "known"?
Here's another question. At the beginning of a tournament, and lets say its this 33R for example...Would you say lump sum everyone at the table as being a donk until they develop an image?? Or, would you say try to have no pre-conceived image of their play and simply develop it as time goes by??

I'm not sure which mode of thinking is more appropriate. The lower the buyin I'm usually apt to lump them all together as donks until I pick up on that someone plays TAG more, or LAG, or maniac, etc....
