nice page. this is something i had considered doing but never did, so you've saved me the effort. the only thing i can think to add is that in superchess (www.superchess.nl), haerington uses princess for his B+N piece; and the physical piece he designed to represent it is somewhat princess like - the piece has a shorter skirt and a crown. (he also uses empress for R+N, and the piece has a long dress and a fancier crown.)
An excellent summary, indeed. Just to establish the futility of trying to get a standard name out of all this, I noticed that my Thronschach calls the piece a Cardinal, and my ABChess later the same year calls it an Archbishop. :) History is on both sides, and for Princess as well. But I also like Fergus's reasoning for Paladin.
Error on the big diagram! One of the dots should be blue instead of green! --Jared
A Cardinal (or as I prefer, Paladin) can mate by itself, although it is not a force mate. _________________ | | | | | K | | | |____|_____|______| | | | | | | | | |____|_____|______| | | | | | | | P | |____|_____|______| P stands for Paladin, K for King, and they are (obviously) opposing pieces. If you can get the enemy king into the corner, this is a mate.
Nice summary. I just want to add name and date for Janusschach: It was invented by Werner Schöndorf in 1978. Another game using this piece is my Quintessential Chess, designed 2002 for the 84 squares contest. I decided to use the name Janus for this piece.
Yes. King and 'Cardinal' can mate lone King: On an 8x8 board the checkmate takes 17 or fewer moves. See http://www.chessvariants.com/misc.dir/endgames.html (Analysis by Dave McCooey, who refers to the B+N as a 'Pegasus'.)
Repeating my 2001 comment. One web page for Cardinal Super Chess states: 'Because of the Cardinals' unique movement, a combination of a knight and a bishop, it gathers the initiative into one sweeping action.' This naturally leads to the mistaken conclusion that it is the usual B+N piece. But the second web page given for this commercial variant shows the move to be a non-leaping Camel. I tested the piece on the applet provided and saw the program move a Bishop to block my Cardinal check.
A fun position featuring the BishopKnight and RookKnight. white- BNg4 RNh4 black- Kg7 Nf6 Rg5 1.BNe6mate. A pure mate, it seems. Pure Fantasy. I hope readers enjoy this kind of comment, instead of debates about the 'correct' name for a piece, ect. I hope this generates some comments, maybe people should write about particular positions like this more often!?
From an altered Dolmatov endgame comes a BishopKnight position- White- BNd2 Kf1 Pf2,g3,h2 Black- Rc6 Qe5 Kh5 Pd4,f5,g7,h6 1.BNf3+ Kg6 2.BNxe5+ Kh7 3.BNxc6. The BishopKnight was driving, diving, jiving, and high-fiving!
Take a position from the 1973 Moscow Championship, switch a knight into a BishopKnight, make a few minor alterations and you get this: White- BNd4 Rd3 Be3 Kf3 Pg4,h3 Black- Ra2 Bc5 Nd7 Kg8 Pg7,h4 A quadruple attack! I like such positions, I think they're great.
Does this piece and king mate a lone king? How? Is it similar to KNB vs K? Does it work on any rectangular board?
Use the "Try it" link in the Notes section, and start playing for black to see how it is done.
