To be fair in commercial issues. For Android phone, Lauri Paatero published new AI and good SGF-editor called Hactar. The AI is server based so it needs an Internet connection to play. For iPhone and iPad, top AI is Rémi's CrazyStone (called Champion Go). I have hard time to beat it.

I think that the main problem was not winning or losing a mirrored game but the blunder in late endgame by playing suicidal move. Perhaps Zen was losing the game, so this was the reason for the blunder. But if Zen was winning, then it was serious bug and it had nothing to do with the mirroring

Most of the random go games are around 500 moves long. As there are on average 10-360 possibilities for branching, there we can easily calculate total number of games. If we know the math. Note that longer than 500 move games are rare and they can be ignored. My Tessa will give you fair
