Here is how designers keep Knights and Bishops comparably powered:
http://www.chessvariants.org/index/displaycomment.php?commentid=23705. By 4x4 and ever upwards Knight naturally reaches all the squares unlike Bishop. Even on this 11x11 that is as important as more and more difficult paired Bishop coordination. Actual players may find Bishops the ones lost and regionally confined and Knights mobile for useful half or so the board anyway of 10x10, 12x12. So Knight and Bishop continue to make equal exchanges in 90% the array-mixes and rules-melanges on any size rectangles, most cases even 20x20 probably, by hook or by crook.
