In the sequence, ABCDE*F*GHIJKLMNOPQRSTUVWXYZ0123*4*56789, the *4* and *F* are symmetrically positioned. Black, having *F*, can only switch any two of 'a' through '3' that are spaced a Knight's distance apart. White, owning *4*, can only switch any two of 'g' through '9' that are spaced a Knight's distance apart. Or for any two tiles a Falcon move apart instead, White requires at least one of them to be a,b,c,d,or e and Black correspondingly at least one of them to be from 5,6,7,8,9. Sometimes moves appear to be waiting moves with apparently minor effect. On the other hand, the board's being only 6x6 means there are as few as TWO steps to victory in favourable circumstance. That's the luck of the draw, and a series should be at least 4 wins of 7 games played. No backswitching the same two tiles just moved, but at 1 1/2 turns it is okay again. White moves first, and both first moves must permanently remove 'F' and '4' from their initial position, or at the earliest opportunity. Afterwards any legal tile-pairs switched -- along either knight- or falcon-distance with appropriate numbering/lettering -- constitute a move. After Move 1, moving 4 and F on a turn is purely optional, but many or most moves involve them. [ALPHANUMERIC version one here does not distinguish among for example {ghi...xyz0123} which could be represented instead by just one single symbol. However, other versions can make finer distinctions, involving up to all 36 ordinally; and challenge of version one partly is to see through the ''noise'' for good pathways. Just don't play computers who won't be bothered in the least.] Sample first move: 1. 4-ce,five + m-ay,six;... your move
