First of all, how can I avoid the automatical numbering installed here, which is not useful for the purpose of entering games ?

I wonder about the quality of entering chess games in databases. The most recent entry I found in chessgames.com was the one above, but not the only one. In a game of the reykjavic open there was also a game where the last move was absurd. It was a rook end game and the last move shown was Rh8, which would simply give away the rook ( I do not remember the game).

Why do regularly appear such errors ? Are the games entered manually or is there an electronic devise which produces such annyoing errors ?

Answer 1

I guess the answer is "both".

Usually (in lower leagues and opens) games are entered manually, which obviously can lead to all kind of errors. But top level games are recorded by electronic boards, which can lead to trouble if the players are moving too fast or are positioning the pieces imprecisely. And there is the constant annoyance of arbiters placing the king on the central squares to input the result, which is quite often interpreted as an actual game move by the electronic board.
