2011-03-30George Duke Verified as George DukeNoneThe user asks ''what are the piece values?'' in a leading question. Zen's landscape is superficially hard for what can be the value of a Pawn that can take Queen as Queen, Bishop as Bishop, Rook as Rook, and so on? And value of Queen that cannot take Knight as Queen but only as Knight? Variationists tend to neglect values even their own cvs as too challenging. Since Brown carefully computed Centennial Chess piece values twelve years ago, maybe 5% of new cvs have even first approximation attempted. The rush is to be the first with some rules-set twist rather than to delve with depth and quality including obvious need to approach the values of units. Okay here in Moss Chess the operating principle is that the regular low-value units get inflated and the high-value ones get deflated. In Moss the Queen for instance captures like everybody else but still has benefit of moving without capture the exclusive Queen way. So how advantageous is that? Try this table as first approximation: Queen 6.5, Rook 4.5, Bishop 4.0, Knight 4.0, Pawn 2.75. The over-all total value has to be considered high, like cvs that plug in arbitrary Carrera compounds to fill out 10-wide. Zen or Moss Chess piece-types are divergent in moving and capturing differently. Unlike Divergent Chess and others, Zen/Moss units take same-type opposites conventionally, so they are not fully divergent -- except the Pawn herself as usual.View [*]
