I have seen a game of CWDA where K& Charging Knight has managed to checkmate a lone king. I was first not expecting this but it now seems normal especially if the attacking pieces are "above" the defending king. I'm not sure if it works otherwise. Anyone else knows anything else on that?

It's strange, I've had this problem with Sergey, too, but only in Shatranji.  I'm playing a number of other games with him and they're all fine.  But in our Shatranji game he kept going back again and again when I would make a nasty drop.  Eventually he resigned.  I suspect he doesn't understand the drop rules.

I'll see if my wife is interested in translating something about drops, or maybe the Shatranji page.  (She's fluent in Russian but not in Chess variants...)

Carlos was jumping the gun about him. He was using translated pages, and these weren't sending the correct submit values to Game Courier. I recommended that he use English pages, and in the meantime, I fixed the problem with translated pages, so that they would work too.

Okay Fergus, I replayed my move (at the point before I dropped a captured pawn on b7). If it happens again I'll be tempted to just delete all my games that I have with this player, depite that I think I'm doing fine in all of them. Remember, he is the one Carlos complained about earlier.

Thanks, I have added Nishiki-teki to the page.

He might have done it accidentally, since he repeated the same move.

I'd like to nominate Nishiki-Teki. It's a cartoony "pop" font that takes a manga-styled approach to the detailed "traditional style" (kings and queens with decoration, rooks with masonry, knights with bases, realistic pawns) chess symbols. It also has variant pieces in its very extensive Private Use Area, mostly following Quivira's lead but with a few others from Unicode proposals, from U+FC2E0 to U+FC39E. The site is bilingual in Japanese and English.

To complete my examples of justifiable underpromotions in Seirawan Chess, here's a diagram where the move 1.Pf7-f8=A+ is the only way to win, underpromoting to an Archbishop. Note that if Black's king were initially on a8 (for example) then underpromoting to a Chancellor would be the only way to win.

Try it again. It should be fixed now.


wdtr2 wrote on 2018-09-18 UTC

I was doing some tests, and I found this: 

1) I was playing shogi agains myself via the play button

2) I was using the symbolic set

3) I move the king pawns forward (both sides) until there is a capture

4) I move the rook in front of the king

5) I slide the rook to the promotion area

6) I prompt comes up "do you want to promote the rook ( +r-dest)  I think"

7) I click the radio button for yes, and then hit play

8) a warning comes up you are about to send insecure information do you want to continue

Note: all urls from step 1-6 are https

9) some time of crash occurs and I get a default chess program at step 0

My best guess the "prompt" command is using http and not https.

I can send all my shogi moves if you want a log.

I got the same results on Linux Mint, and I found a site with a font preview that confirms it. So, I have moved it to the list of free fonts. Thanks.


Garth Wallace wrote on 2018-09-18 UTC

The last one does on my computer:


So I was wrong, the font name is Noto Sans Symbols, not Noto Sans Symbol. The other two match DejaVu Sans on my computer, which is probably the first fallback in my font stack.

Here's a possible Seirawan Chess position showing underpromotion to a Chancellor (best option, though not the only way to win). After 1.d7xc8=C+ ka7-b7 2.Cc8-e7+ White mates in two more moves. This appears to be faster than if White chose an Archbishop or R, while choosing a Q would stalemate Black.


Kevin Pacey wrote on 2018-09-17 UTC

@ Greg: I thought of a way to underpromote to a Chancellor just this morning, but felt it was too easy and not what you were initially doubting was feasible in the way of a justifiable underpromotion. I'll see if I can remember what I thought of.

Meanwhile, here's another Seirawan Chess possible position, this time with an underpromotion to a rook (I feel I thought of some other example position that was more crystal clear long ago, though); White's easiest way to win (if nothing else) is 1.Pe7xd8=R since if White chooses a B, Archbishop or a Q instead then 1...ac8-g4+ allows Black to at the least bother White for a while, since taking the archbishop stalemates Black. If White chooses a Chancellor instead then 1...ac8-b7+ may prolong the struggle considerably since taking the archbishop with either Chancellor stalemates Black.

Do any of these tests show the same pieces as displayed on my Kindle Fire? They don't for me, not even in Fedora, which I tried with Virtualbox. It came with some versions of Noto Sans, but not Noto Sans Symbol.

Testing for Noto Sans:

♔♕♖♗♘♙ ♚♛♜♝♞♟

Noto Sans Symbol:

♔♕♖♗♘♙ ♚♛♜♝♞♟

Noto Sans Symbols:

♔♕♖♗♘♙ ♚♛♜♝♞♟


Garth Wallace wrote on 2018-09-17 UTC

Fedora (a fairly old version thereof, since I'm not very dutiful about upgrading).

I wonder if Mint messed something up in their distribution? It doesn't make sense for them to deliberately take them out, and it's not like they're new additions to Unicode (they've been included since Unicode 1.0).


Fergus Duniho wrote on 2018-09-17 UTC

That's where I got it from last night. I have already checked the Noto fonts on Linux Mint, but they didn't seem to include their own Chess pieces, and I never saw the pieces I saw on my Kindle Fire on Linux Mint. What Linux distribution are you using?

Heterodox chess piece Unicode proposal[Subject Thread] [Add Response]
Garth Wallace wrote on 2018-09-17 UTC

An update on this: the proposal was ultimately accepted. The final proposal mostly covers symbols from the fairy chess problemist tradition (e.g. rotated pieces), but does also include the knight-rook, knight-bishop, and knight-queen compound symbols. The characters are currently planned to be added to Unicode 12.0, which IIRC is scheduled to be published in March 2019, in the new "Chess Symbols" block (U+1FA00–U+1FA6F) that was added in Unicode 11.0 and currently includes symbols for Xiangqi.

Give me a link where I can download the version you have or see this for myself.

@Kevin Pacey

Nice one!


Kevin Pacey wrote on 2018-09-17 UTC

Here's a possible position from Seirawan Chess where White's best move is clearly 1.Pd7xc8=N, since promoting to a bishop or archbishop instead is meet by 1...ab8-d6+ and if the archbishop is taken by a White archbishop then stalemate occurs.
