Oddities With Chess Publisher

If you have tried to follow my game against Anatoly Tsinker, you will see a very strange thing happen. For blacks' 18th move of Ng4, it takes the knight from a4 and moves it to g4. Then for black's 19th move of Bf6, it plays Bxf6. (It's capturing it's own knight.) Move 20 for black is supposed to be Kc3, forking my rooks. Move 21 is supposed to be Nxa2. Then the rest of the game seems to play normally. I checked the pgn file, and the moves are fine. It plays through normally on Chess Base. I even reloaded it on Chess Publisher and edited the post with the new link. Same thing! I'm too tired and it's past my bedtime so it's staying as is for the moment.

Anyone else seen this happen before?

I have not used Chess Publisher but I wonder if using long algebraic for the move(s) it is messing up would fix the problem. So, change you pgn to have 18 ... Nfg4 or maybe 18 ... Nf6-g4.

I suspect the software consists of a "parser" of the pgn that generates the list of moves to make and the "parser" has a bug..."disambiguating" your 18th might work around the bug....

I've never encoutered the problem before. Though maybe I have, and just haven't noticed. But it seems to be totally off the wall to grab a knight from a4 and move it accross the board. It's not even an ambigious move situation.

I even checked my Mon Roi notation, because sometimes I've moved the wrong knight when it has been a matter of both knights being able to go to the same square.

In fact the very first tournament that I used the Mon Roi, I moved the wrong knight, and didn't notice it until 4 moves later when the position on the unit didn't match the board. I wasted 5 minutes trying to figure out where I went wrong!

Did you try using Chess Publisher v2? I'm not sure if it would make a difference--I really can't imagine they'd re-write the PGN parser for v2. It would be interesting to see, though.

Addendum: Chess Publisher v1 uses something called Chess Genie. I haven't bothered to ascertain the relationship between the two. Maybe v2 does use a different parser or something.

LOL--chesspublisher has invented a new variant of chess. Chesspublisher sure is quirky.

LEP: I haven't messed around with version 2. I don't like the way it scrolls, and I'm too HTML stupid to try you modifications to keep all the analysis nect to the main line. 1/2 the time when I insert a game, picture or diagram I get errors about incompleted tags. I don't even want to mess with trying to insert extra ones.

BDK: It's called Chess Publisher Random Chess. I wonder if we can market it. If Chess 360 can be castlinglong, I can specilaize in CP Random Chess on castlingqueenside. Though the way I've been playing maybe I'll call it "Polly Random Chess".

The move is not ambiguous (except, perhaps to Chess Publisher, for reasons unknown). I just think making it explicit might help the software to work around its bug...

In fact the very first tournament that I used the Mon Roi, I moved the wrong knight, and didn't notice it until 4 moves later when the position on the unit didn't match the board. I wasted 5 minutes trying to figure out where I went wrong!

How does one correct that in MonRoi? Moving the pieces around until they match the position on the board in an edit mode? Backing up and re-entering the moves?

How can an opponent distinguish that from taking illegal advantage of trying out moves/positions on the MonRoi?

Can you post the pgn for the game? I'll give it a go.

It works fine in v2. It's not harder to use than v1, codewise, as long as you don't bother using my tinkering. :D

Yes, I experienced that before, also with a Chess Publisher choosing the wrong knight to jump to the wrong square.

See 13....Nh6 in this post.

The the Flash program on Chess Publisher is actually a Chessgenie. You'll find the (original) latest version on http://www.rootyhillchess.org or at its blogsite www.chessgenie.blogspot.com
