Maorider[Subject Thread] [Add Response]

Mike, the value depends at least in part on how big the board is. On an 8x8 board a Maorider is worth comparatively less than on a 10x10 board. If you use Betza's modification of empty board mobility (found <a href='../d.betza/pieceval/betterway.html'>here</a>) for an 8x8 board, you can calculate a value of a Maorider. If I read it correctly, it would be 0.68275 the value of a Nightrider. Now a Nightrider is generally accepted to be worth a Rook and Betza follows Spielmann in assigning the Rook a value of 4.5 Pawns, yielding about 3.07 Pawns for a Maorider, or right in the Bishop/Knight ballpark. <p> Of course, Ralph has expressed doubts about these values from time to time. However, given that the Maorider is awkward in the opening, and limited in the endgame (I don't <em>think</em> K + NN vs K is a win, never mind K + nNnN vs K), the value seems OK to me.
