I used my solver to analyze all 36 games in Group 1.

22 games were played perfectly. Some of those still ended in 2:0 though, as the 2nd player timed out.

The 14 games below had suboptimal moves, which we'll call blunders.Each blunder is preceded by an optimal alternative between parentheses and followed by a = or + to indicate that the player to move has a draw or win. The question marks in game #1724612 indicate that I have yet to pinpoint the exact ply at which the game became a draw.

Congratulations to santi for perfect play without the help of a solver!

Curiously, there is 1 point blundered on average over all 36 games.

I am in the process of preparing a public github repository with the code and opening book for the 8x8 solver.

Stay tuned…

thanks for shearing the analisys. congrats, seems your code works.I will stay tunned abour your research!

Care to explain why it's possible to lose games with perfect play i.e. no blunders?

fhourplay, how close are you to solving 8x8?

As the second player has a theoretical win you can lose by going first.

He already solved it.

I have since confirmed that the position after 775 is a draw, with 6 the only drawing move. So the above becomes
