Ordo X Notation

The notation system for Ordo X is the same as for Ordo.

Removing an Opponent’s Group

An isolated group can be identified by the most advanced and leftmost member piece (seen from the player’s perspective).

That is, if you want to identify an opponent’s group because you have to decide between 2 or more isolated groups of equal size, then you simply notate the coordinate of the enemy piece in the corresponding group which is next to you and (secondly) the leftmost piece in the row.

The white player notates here: e3xe7(h6) if he wants to remove the right group.
