Hello everyone!
I am excited to release a new feature that adds a whole new layer of depth to local Play vs Computer matches: Variation Mode.
This feature is fully supported in both the Internal Engine and UCI Engine modes.
Have you ever been in a tough position and wondered, "What would happen if I tried this risky move?" Now you can find out without losing your actual game progress!
How it works:
Create a Variation: Instead of using the Left Mouse Button, use the Middle Mouse Button (Scroll Wheel Click) to drag or click a piece to a new square.
This creates a temporary "branch" of the game. You can see exactly how deep you are in the analysis from the Variation Depth counter on the screen UI.
You can create up to 999 nested variations, so feel free to explore as deep into the game tree as you like!
Step Back: To revert the variations one by one, simply click the Green Back Button or press Backspace. You can keep doing this until you return to the main game.
This feature is perfect for analyzing positions, testing traps, or simply learning from mistakes in real-time against the AI.
Note: Variations are not saved with the game replay when using the Save function; they are only available for the duration of the current game session.
Other improvements:
Added a check to ensure save files exist before allowing "Continue Game".
General stability improvements for the undo system.
I hope you find this feature useful for your analysis and enjoy using it. Happy analyzing!
