creat chess pgn file containing multiple puzzles using tarrash

This script requires the Requests and Python-Chess libraries to run, as well as a copy of Stockfish It uses a different approach to create tactics, so probably it will generate a different set of tactics. I created a more user friendly tactics generator and it's online There is another option if you don't want to install and manage python scripts This is too complex, give something easy. chess.pop_count to chess.popcount, because it was failing.You can use the depth argument to change the depth if you want more precision.So it took several minutes to analyze a game. Before it was nodes=3500000 this is a depth around 20. Default engine depth to 8, so it's faster.Write results to a file called tactics.pgn.Use a local pgn file with games as a source.It's based on the great by that I changed: See This is a very powerful tool.This is a python application dedicated to creating chess puzzles/tactics from a pgn file.Īlso it can download your games from and use that file. For example, create a 'tagfile', and write the following in it:Īnd you will get 500 files by ECO code, each containing only games in which both players have Elo at least 2400. You can also apply other filters like minium rating etc. 'pgn-extract -E3 *.pgn' will create 500 files A00.pgn to E99.pgn. But instead of this, you can simply ignore at most 999 games if you have split the file in 1000 parts.Īfter doing all this, you can use pgn-extract to sort the contents of all these files into ECO codes. If you manage to run the split command, then the rest will be easy with small scripts (using e.g., bash, sed, awk, perl or python). If so, look at the head of the next file 38.pgn, and get the remaining part of the game from 38.pgn and add it at the end of 37.pgn and remove it from the beginning of 38.pgn. For example, you can check the tail of each file, say file 37, to see if it has been split in the middle of a game. Maybe you can fix this issue manually after the split. The split may happen in the middle of a game. I hope you won't face memory issues in using this tool.

It is also possible to specify the number of bytes in each file. Check 'man split' to see what other options split offers. But I think zip itself allows the split option, so any other modern zip/unzip tool would have the option. The simplest usage will be something like the following (in a terminal), which will split a file into 1000 partsĭo this after extracting. You can perhaps use the linux split command to split the file into as many files as you want.
