[math-fun] Another chess variant

I just saw this a couple of days ago on YouTube: The idea is to pit K of one piece against L of another in the context of avoiding checkmate. Two different pieces, one for each player, are chosen, like K white queens and L black knights. The W and B kings are in their usual starting positions; the rest of the squares on the board are filled up with (say) the K W queens and L B knights. Like (lowercase = B, uppercase = W): n n n n k n n n n n n n n n n n n n n n n n n n n n n n n n n n n n n n n n n n Q Q Q Q Q Q Q Q Q Q Q Q Q Q Q Q Q Q Q Q K Q Q Q (Of course the numbers K of W and L of B pieces need not be of form 8J + 7.) It might be interesting to determine which ratios of which pieces lead to a fairly even game. —Dan
