Strong vs. Weak

What's a gosu? I do have to agree with what you say about confidence.. or lack of it.. making so much different and how well you perform. Consistent losing doesn't exactly enhance my confidence, I find.

Noob, gosu, pro-gamer are benchmark terms that we use in video games. The evaluation is done by the technical level (not really by a display of level) example in Warcraft 3 a level 8 to beat Grubby (pro-gamer) but "we know" that it is a gosu by technical level that we notice in particular in his strength in micro. 

In chess it would be + 2000 without it being by an artificial progression. Often we can't beat an AI at 2000 in many programs because we don't have the technical level to do so, so we conclude that from 2000 we are gosu (but obviously if we use anti-computer techniques, make take backs, don't play in the same time, it doesn't mean much to beat an AI 2000 ). 

I see.. I guess..🤔

Everybody has an opinion about it.. There are elements in truth in what all of us are saying.

In (stable) 2000 vs (unknown) 1700 case you have the following possibilities: A> the 1700 is stable and the 2000 needs to score almost 90% to break even (reasonably likely); B> the 1700 is declining and the 2000 needs to score almost 90% to break even (will probably exceed 90%); C> the 1700 is improving and the 2000 needs to score almost 90% to break even (if the [probably young] 1700 is really 1800 strength then the 2000 can expect to lose a bunch of points).

The improving players are more likely to be active and thus the chance of C is likely quite a bit more than the chance of B.

Wish I could. 😑

The bigger the rating difference the less precise the rating predicts the game. 2100 should beat 1700 10 times in a row which is not the case.
