Question on Mon Roi pgn

[Roger Patterson]

I've having some problems with Mon Roi pgn from their website. For example, take the game Moore-Yoos from the 4th round. Playing through the game on the mon roi game viewer looks OK, and if you get the score on the side of the game viewer you get:

1.c4 e5 2.Nc3 Nc6 3.g3 g6 4.Bg2 d6 5.d3 Bg7 6.Rb1 a5 7.a3 f5 8.e3 Nf6 9.b4 axb4 10.axb4 O-O 11.Nge2 Ne7 12.O-O c6 13.b5 Be6 14.Qb3 g5 15.f4 gxf4 16.gxf4 Qe8 17.fxe5 dxe5 18.Ba3 Ng4 19.Rf3 e4 20.dxe4 Ne5 21.Rg3 Bxc4 22.Qb4 N7g6 23.bxc6 bxc6 24.exf5 Rxf5 25.Nd4 Rf7 26.Bc1 Rc8 27.Ne4 c5 28.Nxc5 Bf8 29.Nc6 Rxc6 30.Bxc6 Rf1
0-1

which more or less corresponds to what I saw of the game. But if you click on the button for pgn you get:

which is basically garbage (doesn't even begin with the same first white move. ). The scoresheet button produces a similar result. Probably half to 2/3 of the games I have tried to download have problems like this. Anyone know what's going on?

I have no explanation for the game you mention, but I too have had problems with Monroi PGN in the past. Here is a game I tried to look at last summer:

In this case there is an obvious notational error, the use of the capital "D" on move 3. Chessbase does its best to continue interpreting the game by looking for the next legal move in the position, but the result is gibberish.

Re: Question on Mon Roi pgn

I also have had problems in the past with the odd Monroi PGN game (such as the capitalized "D"), and simply reconstructed it. This is the first time I've seen such a large number of games with errors. Assuming one player is using the Monroi and the other isn't, I usually compare the numbers of moves in the Monroi PGN file with that on the written scoresheet. If they match - I can assume that Monroi has the correct number of moves.

Try contacting Monroi, and report the problem.
