program to generare epd file of tactical exercises from pgn

I would like to generate epd file of tactical exercises from a pgn and I wonder if there is a program that can do it. I would like to have the following epd files based on a pgn game: 1)good moves in the pgn that are significantly stronger than the second best move 2)good moves from positions in the...

Re: Could this be the best game of all time by a Female Player?

The problem of Hou yifan is not playing against weak opponents. Hou Yifan does not do well enough against strong opponents to increase her rating. Maybe it is because she does not invest a lot of time on chess but the facts are that hou Yifan is clearly weaker than the level that Judit Polgar got in...

Re: MCTS: How to deal with extreme imbalances

I think that the best way is to change the scoring system so mate in 200 moves is worse than mate in 100 moves.

For example winning give the winning side 1-0.0001*number of moves and the losing side 0.0001*number of moves.

In this case mate in 100 gives 0.99 points and mate in 200 gives 0.98 points.

is there a program to translate epd file to diagrams?

I generate epd file when I add every day positions to the file and I would like later to have a word file with diagrams of all the positions in the epd file. I wonder if there is a free program that can translate the epd file to a file of diagrams that you can open by word. I would like to have also...

Re: LCZero blunder

I think that Qxf4 is a positional mistake and not a tactical mistakes. A-B Engines that are positionally weak can make this mistake. top A-B engines are simply positional monsters and not only tactical monsters so I guess that they do not do this mistake even after one second of search but if you gi...

Re: Lc0 with latest test30 nets is vastly superior positionally

This doesn't surprise me although its good to have some data showing it. As you said, its tactically that Lc0 has some weakness which gives it a little human like behaviour where it can loose in 25 moves tactical combination to SF dev and the following game show a positionnal master piece vs SF dev...

Well, this is end of an era for Houdini and Komodo.
This mean Leela become 99.9% best engine within a year!
Beating SF will become 100%.
I do not understand how do you calculate it.

SF may improve in the next year and same for komodo and houdini.

Re: Who has garbage endgame evaluation?

The position is not obviously dead draw. It is a draw if you play perfectly but in a tournament game against humans I am going to continue with white and try to win. I know white has a practical chance to win when black does not have practical chance to win(assuming white is not a very weak human pl...

Re: What is the minimum odd that you can take to play Vs SF ?

A Rook is much too much combined with White pieces. SF 9 with 2 cores and 512MB, thinking window and graph disabled during play. TC 40/480, 5men Syzygy for SF. BTW SF went straight into time trouble for the first time control. No idea yet why my times were not saved and I forgot to set a different ...
