What's New in Version 1.5 - peteschaefer/jose GitHub Wiki

The most recent release was in 2006. This project has been lying dormant for almost 20 years. Sorry guys, I've been busy.

The GUI looks a bit old-fashioned in some corners, but the functionality is all there. What I like most are the editing and printing capabilities.

Now there's new stuff to come:

1. Stockfish and Leela Chess Zero bundled

  • for play and analysis
  • any other UCI-compatible engine can be plugged-in, as usual.
  • bundled Lc0 is meant for minimal hardware requirements.
    If you have a more powerful setup, you should use that one! (see [Installation Notes](Installation Notes))

2. WDL and other Leela scores

  • supports Win-Draw-Lose scores for both Leela and Stockfish
  • supports all the Leela score types (win percentage, Q, WDL_mu, etc.)
  • prints a ton of Leela diagnostics (Q,N,V, etc.)

3. Node-restricted search

  • perform engine searches with fixed time, fixed depth, fixed node count.

  • and, as before, with flexible time controls.

  • press F9 (Edit / Options), select 'Engine' tab to edit all the engine settings.

  • also have a look at the 'Opening Books' tab; you can have the engine play with, or without, Polyglot books

4. Lichess Opening Explorer

  • use the Lichess database as an online Opening Book (in addition to Polyglot opening books on your on hard disk)
  • it is not enabled by default: go to Edit, Options (F9), 'Opening Books' tab, check 'Lichess Opening Explorer'.
  • push the analysis button Bildschirmfoto vom 2025-01-21 08-44-06.png. During the opening phase, the button toggles between opening book and engine analysis.
  • top games are listed for popular variations. Click to download the game.
  • color transpositions are detected

5. Eval Bar and Eval Graph

6. Analysis arrows

  • show best moves while analysing (not during engine play)

7. Threat Analysis / Null Moves

You might know this feature from other chess analysis programs. Of course, it is not allowed to make a "pass" move in a regular game. But in analysis variations, it is a useful device to analyse a position from the oponent's point of view.

  • push the Threat Analysis button Threat Analysis
  • inserts a new variation with a "null" move

Thread Analysis

  • "..." indicates a skipped move, or "null" move
  • the delta icon means "with the idea", or "threatens"
  • any number of null moves may be inserted, like so:

Thread Analysis

8. "New Game from here"

  • starts a new game from the current position. This is a handy feature to play a set of training games from a specific opening variation.

9. Connect to Chessnut Air, Air+, Pro electronic boards

  • only on Windows, and only with a USB cable. Bluetooth is not yet reliably supported.
  • board orientation is detected automatically (as long as h1 is a light square ;)
  • take back allowed
  • take-take sequences detected
