Man and Beast 02: Shield Bearers. Systematic naming of divergent coprime radial pieces.[All Comments] [Add Comment or Rating]

The only measure to get solid information about the strength of a certain piece is to playtest it (in human play and/or computer play). As far as I know, there are few divergent pieces really tested.

Mike Nelson's Seperate Realms Rook comes out on a value of about 75% Rook plus 25% Dabbabarider, suggesting that capture constitues about 3/4 of the piece value, while moving alone constitutes about 25%. But this particular piece has rather similar move and capture patterns; the more the patterns diverge, the more playtesting is needed, and there is probably no simple formula describing the results.

Note also that the results of playtesting depend on the testbed: What board is choosen, what is the oppenent's army, what pieces are in the same army (sociability effects).
