This is the easy answer to that question. Please ask >further questions if you dont understand. If you read my question, then maybe it was not clear that it was meant as a rhetorical question. My point is that obviously Hagra has NO clue what the uncertainty in the quoted rating numbers is. But this he already confessed in another post. Of course the advantage of having a bunch of chess programs play games against each other to determine their relative strength is that the uncertainty in the estimated relative playing strength will become smaller if more games are played. The advantage of having them analyse positions from human chess games is that we can see how good they are in analysing, a feature that is of most importance to most users. Geert
