Generalizing the two-bishops bonus[Subject Thread] [Add Response]
Greg Strong wrote on Sun, Dec 17, 2017 12:18 AM UTC:

In Chess, the bishops are worth 325 centi-pawns plus an extra bonus of 50 if the player has one of each color-binding.  Or you could consider them to be worth 350 each with a penalty of 50 for losing one of them.

In ChessV, I now want to generalize this...  A simple approach would be to give a flat bonus of 50 for any player that has at least one colorbound piece on each color binding.  (This would automatically not give any bonus for games that don't even have colorbound pieces.)  But is this right?  Consider the Colorbound Clobberers.  It seems if they have only one BD and only one FAD and they are both on the same color, this is probably a huge disadvantage.  The enemy can evade two pieces at once by staying on the other color.

Another question would be pieces with even stricter bindings like a Dabbabah which can only see 1/4 of the board.  I'm probably not going to really consider this for the time being.  I'm not sure it currently plays any games with 4 Dabbabahs on each of the four bindings.  It will become a relevant question, however, when it plays Hexagonal where there are 3 different bishops...
