Constellation36: These games (Plakoto & Fevga ) do know gammons and backgammons actually
You are correct about the backgammon.They don't know backgammon,but the DO know gammons.

As for the second about motherpins,I have only seen it once.If you play "correct"then there is no way you will win just 1 point for the motherpin checker. This happens one in a million or even one in a billion. I myself never won a just 1 point when capturing the motherpin...
