XX resigns not because the 1st group is bigger. In fact, the first two groups will be equal: 1st have size 15, then the next groups have size 7. Only then, the 3rd o-group have size 3, while the x-group has size 2

If the players made all the moves, the board would become:

A board of Makru, the Thai Chess:

And a strange board that I don't recognize (the label was wrong, it said that was the Makruk which cannot be right):
