Bobos number four, four piece-types. Bo-Bo is like double Bishop, but the
second is only 1/4 of the possibilities, yet fully 1/2 of a second Bishop's capabilities. There are upper left, lower left, upper right and lower
right Bobos(orienting from lower left). The extra diagonal allowed, adjacent and opposite colour,
removes colourboundness from Bobo. Let's call the 4, BoboUL BoboLL, BoboUR
and BoboLR for now. The standard Bobo array goes ROOQKOOR on 64 squares. There is no need for Knight any more. We can start to think about hybrid of Bobo and Rook. We don't know yet what that would look like. If we achieve hybridization, then there is only one piece-type, like Battle Chieftain,
 to go with King and Queen. Reductio ad absurdum, versus proliferation in some sense. Polar opposites with some sense. Because of often observed cumulative effect, operable most cases of lower-value pieces, the accrued value is not 3.0 plus 1.5 only equal to 4.5. Actually there is initially a damping for the 1.5 to maybe 1.0 if that, the half a Bishop leg, and thereupon, once that is guaged properly at (below) 1.0, the accruing to nearly 5.0, not quite to Rook, 3.0 plus a temporized ''1.0'' here compounds to 4.6, 4.7. These are preliminary, that we would still slightly give edge Rook to Bobo.  Bobo is a good-valued piece in a useful range, like Bifurcators or Bent optional second leggers, if Joyce would scale them back somewhat.
