And in the meantime, I also noticed something else, after playing version v1.2 for about half an hour. Even if I set the CPU-strength to "sharp", the computer sometimes makes senseless moves, e.g. when the black 8 is the one, closest to its own ball. Then the CPU frequently shoots the 8 into one of the nearest pockets, even though, you aren't supposed to sink ball 8, if there are still other balls on the table.
I also noticed, that the CPU plays very weakly on the "easy" and "fair" settings. But "fair" is essentially the medium difficulty level, so it really ought to play a bit better there, if you ask me. And it would be also nice, if there would exist a "super sharp" mode, as the strongest mode, because even on "sharp", I’m already winning the vast majority of games now, despite not having known and played this game for really long. When you’ve known a game for a while and play it frequently, you get better and then the current CPU in your game, doesn't stand a chance anymore, not even on the "sharp" setting. And then there's the danger, that it becomes boring, because you also don't have human opponents on hand always. Cheers.
