More capturing move types than non-capturing move types. 2. Majority of capturing move types are non-replacement. 3. At least one piece with an important special power (e.g. Immobilizer). #3 is not a strict criteria but is indicative in borderline cases. Chess On A Longer Board . . . is clearly a Chess variant with Ultima elements by these criteria. Edit Form You may not post a new comment, because ItemID Ultima Variants does not match any item.
