Re: Classes of chess pieces for chess variants

HGM, On the CirSquare board, the R and Q being able to single-handedly mate a King seems to be similar to a R or Q being able to mate a K that has been left behind 3 Pawns after castling and the R having moved out. It also seems similar to fool's mate in chess where the Q mates the K by herself in 2...

Re: Classes of chess pieces for chess variants

HGM, I'm sorry about the broken link. I was advised by a patent and trademark attorney that there is a high probability that I would be turned down for a trademark for "Thrones Chess". He said Game of Thrones has a chess game called "Game of Thrones Chess Set", which makes my requested trademark too...

Re: Classes of chess pieces for chess variants

HGM, A circular board has no corners to push a king into where it has a maximum of only 3 escape spaces. Spaces next to a sidewall provide a maximum of 5 escape spaces. With the board being 50% larger than a classic 8x8 board, it takes much longer to push a king against a sidewall or to push a king ...

Re: Classes of chess pieces for chess variants

HGM, I just played one game all the way through making sure I moved all the pieces. I promoted 2 Pawns for each side. Performed numerous checks. I captured everything except the 2 kings. I forgot to check the checkmate condition. All the moves worked properly, except for a king in check next to a wa...

Re: Classes of chess pieces for chess variants

HGM, Excellent! Following your latest directions for opening WinBoard for Thrones Chess works perfectly. Now the board looks great and moving the pieces works great. I have only moved a Pawn and a Knight. I will move all the pieces and check for proper moves against the CirSquare 96 board with notat...

Re: Classes of chess pieces for chess variants

I uploaded a zip file with the converted Fairy-Max as I have it now, plus WinBoard, configured for playing on the cirsquare board, to http://hgm.nubati.net/ThroneChess.zip . When you launch the winboard.exe in the folder, it should automatically switch to 'variant throne' (as I called it), because ...

Re: Classes of chess pieces for chess variants

HGM, I did not like my original rendition of your Fairy-Max 12x12 board because of my use of red squares to indicate squares that are not used by the CirSquare board. I went back to the idea of your original drawing of the 12x12. So I switched to using 'X's over the numbers for the unused squares an...

Re: Classes of chess pieces for chess variants

HGM, I finished checking all the rest of the Knight moves by using the CirSquare board numbered with 12x12 numbers. They all checked out good. So the only 4 that needed attention were the 4 that referenced a triangular space as a move. The CirSquare board with the 121x12 numbers makes it very easy f...

Re: Classes of chess pieces for chess variants

HGM, In your table, it is difficult to know when a 0 means square 0 or a non-move. Should the non-move zeros actually be blank--no number at all? How will Fairy-Max tell the difference between a 0 move and a non--move? I am just over half way checking the Knight moves, and they all check out good so...
