Because A 4 P___P___P___P___P___P___P___P on 8x8 sets up in illegal position(!) 3 P___P___P___P___P___P___P___P and so not properly rated.

So equivalence of 60(or 59)Pawns and one Angel(58 or 60) 8 P___P___P___P___K___P___P___P Unlike Angel, Angel-prime(n=6) is bona 7 P___P___P___P___P___P___P___P fide piece on 8x8. Legal initial, 6 P___P___P___P___P___P___P___P no promotion of course. 47 Pawns beat 5 P___P___P___P___P___P___P___P A-p and King, but remove several 4 P___P___P___P___P___P___P___P forward Pawns and A-prime soon finds 3 P___P___P___P___P___P___P___P a square six removed from King, 2 ___ ___ ___ ___ ___ ___ ___ checkmate, proving A-p 39-41 points. 1 ___ ___ ___a___k___ ___ ___ Edit Form You may not post a new comment, because ItemID ChessboardMath does not match any item.
