strength

For all tests I use 8 + 0.08 time control.

Dog on an ESP32 compared to other chess programs:

The elo-rating is anchored to TSCP 1.82 for which the rating was obtained from the CCRL ratinglist.

This is Dog versus "Dumb". Note that only a few hundred games were played. For proper statistics, check CCRL.

Here are the results of different versions of Dog playing against itself (time control: 8+0.08). For version 3.1, the CCRL rating (2025/10/01) is used as reference.
