The Checkmating Applet brings good news! My original creation, the (AmD) Elephant, can team up with a Knight to (eventually) stalemate a lone King. Pieces with four noncapturing moves are unusual in chess variants - the earliest examples I can recall are the Steward (quadra-pawn) in CENTENNIAL CHESS (1999) and the Bishop in Caïssa Britannia.
Knight and Ferz are another effective team, on the 8x8 board they can stalemate almost as quickly as the Knight and Bishop can checkmate. I was aware that a pair of Knights could force stalemate, but it is nice to have it verified.
Longest Stalemate Victory with K+N+(AmD) vs K
in 36 moves on the 8x8 board (98.8%)
in 55 moves on the 12x8 board (99.4%)
in 61 moves on the 10x10 board (99.4%)
