tactics tool
  • Tommah at 2017-08-31

    I want to share a chess training tool that I made recently: https://new.amecy.com/main/checkmate .  It offers a set of practice positions that contain forced checkmates.  You move the pieces, and the page tells you whether you have chosen the right moves.  About 40 positions are accessible so far.  There are more hidden positions in the database (about 900), but I am not ready to make them all accessible yet.

    By the way, you don’t have to sign up to use that page.

    Very nice, I already did the first 4 problems. It made me remember the time when I was 12 and studying chess.

  • Tommah at 2017-09-01

    I should have mentioned that the problems on there are relatively simple.  I will add some more difficult problems soon.

  • Tommah at 2017-09-10

    I have added more positions.  Some of the high-numbered problems (700-1001) are more challenging than the first 50.

    I’ve done a lot of work on the checkmate trainer over the past year, so I invite you again to take a look (https://new.amecy.com/main/checkmate).  The biggest improvement is that the site now maintains a record of which problems you have solved.  If you sign up on the site, your progress is saved for 30 days.  If you use the tool without signing up, your progress is saved until you close the page.

    I also added about 40 more problems to the page.  I have been testing out the rest of the problem set, and I will soon start adding new groups of problems on a regular basis (around 50 per month for the next 12 months).

    I have recently done more work on the checkmate trainer.  The big change is a new feature that will help you if you cannot solve a problem.  You can now click the button that says “Show solution”, and the board will flip so that you can play as the other color.  The computer will then demonstrate the checkmate to you.

    I have also added around 40 more problems, bringing the number to 212.

    I have added 91 more problems, bringing the number to 303.

    I have also begun the process of moving the tool to its own site (https://www.checkmatechamp.net/).  If you want to keep seeing these updates, please visit that site and follow the Twitter account that I mention there (@CheckmateChamp).  I will keep posting about major changes here on LG, but I will save minor news items for the Twitter page.

    I have added about 200 more problems, bringing the total number of problems to 501.

    I have also added some small conveniences (a blue highlight around the computer’s move, and automatically showing the first problem when you visit the page).

    I recently added two big features to Checkmate Champ:

    (1) The site now saves your progress permanently, without your needing to log in.  This is done using the browser’s localStorage object.

    (2) You can now make moves by dragging and dropping pieces.

    Try it out at https://www.checkmatechamp.net/ .
