I will look in to it, this is really fun stuff... :-) I suppose the cases where K + triple compound L can win on arbitrarily large boards involve pieces that are able to all by themselves stop the bare King from fleeing away, with enough time left to spare some moves for the other King to make its approach. Such as a Squirrel ((0,2)+(1,2)+(2,2)), which can stop the King for 2 moves by taking opposition. I guess this is an easy one to do even without a computer, quite similar to the 'mechanical' way of mating with a Rook, driving the King to a pre-chosen edge rank by rank. And about twice as tedious, because where the Rook would fence off a rank once and for all, the Squirrel would have to renew its position every 2 moves to achieve the same...
