It often points you to / which is a good ressource for programming related questions.ģ. Start here: The official Python Tutorial is located here: /3/tutorial/introduction.html You now have a (big) book which contains all moves from the pgn, and the white moves have weights based on how often they are played.Ģ. Without that parameter moves which are played more often get a higher weight in the resulting book file. you create a polyglot opening book, like here: /forum/general-chess-discussion/how-do-i-add-an-opening-book-to-my-bot#3 - but you remove the -uniform parameter for the white games. Voila! Good.pgn will have all the games in the pesky one, and it will work in Chess Hero.You may achieve your goal using these steps:ġ. Now hit the copy button and when asked where to save, tell it to save to good.pgn, that empty pgn file you just made. Use the Shift button on your keyboard to select them all. Fritz will list all the games in the pesky file.

Hit the Database button and load that pesky pgn that Chess Hero refuses. Hit the New button to create a new empty pgn file, lets call it good.pgn

It may not work every time, but it works often.ĭownload Fritz 5.32 from here : Yes, it seems to be freeware now. If it appears with a tag value of “1”, a FEN tag pair must also appear. This tag must appear for a game starting with a set-up position. A value of “1” indicates that the game started from a set-up position this position is given in the “FEN” tag pair.

A value of “0” indicates that the game has started from the usual initial array. This tag takes an integer that denotes the “set-up” status of the game. My guess is that Chess Hero insists on having that written in for some reason. What you are really doing is adding the phrase before every game in the pgn file. Get to the Find and Replace area and type the following into the boxes: Often its icon is a magnifying glass, or binoculars. Once you have opened the pgn file, open up the Find button in your text editor. My current favorite is Ever Edit but any one will do. Open the pgn file in a standard text editor. You do, however, need to feed it pgn files, and some of those files return an error message when you try to load them in Chess Hero, even though they work fine in Arena and other programs. The freeware program Chess Hero is lots of fun.
