Variant on 9 by 9 board with special knights. (9x9, Cells: 81) [All Comments] [Add Comment or Rating]George Duke wrote on 2004-09-13 UTCExcellent ★★★★★First used Cetina's Sissa is the 'Knight', actually moving to Nightrider and Rook squares, but not like they do. In Second Board above, 'Sissa', or 'Knight', on c3 may capture Rook on c5 by Four-Fold pathways: c3-d3-e3-d4-c5, or c3-d4-c5-d5-c5, or c3-b3-a3-b4-c5, or c3-b4-a5 b5-c5. No pieces intervene, but if they did, any one pathway would be sufficient to move and capture c5 from c3. Sissa's 'N-Rider' squares are reachable by two-fold pathways. No Bishops' conversion rule like in Sissa Chess.
