My CARDINAL POINTS tournament situation (new formula) after 3540 games:



Storm, the 35th chess engine written in Scratch (3 days old). Implements:
- Negamax depth 2 (3 on turbowarp)
- Quiescence search
- Alpha beta pruning
- Move ordering (MVV-LVA)
- Delta pruning
- Piece square tables
The project is still in development, but already shows a lot of promise. Country of origin: New Zealand. It's not easy to write such an engine in Scratch.

The 36th chess engine written in Scratch. A top one. Coming from France:
