Atrotos: Agreed.  In the Introduction to Popular Chess Variants, D.B. Pritchard wrote: "All the usual rules, but you also win if you check your opponent three times."

wetware:
The variation I dont likei is extinction chess where you can put your opponentt in checkmate but still lose when your opponent takes, say a second bishop, because you have not taken his king. i would rather normal rules apply in this variation as well.

Justaminute: On another subject for the same variant: does anyone know how the system here handles a double check? does it count one or two checks?

rabbitoid: One.

tangram: Edwin Poels won the 2nd Superchess Freestyle tournament at Leiden.
Some brainking players who played": Tangram, Lambik, Superbutch, Schuli, Karel123.

Did anybody ever checkmate his opponent with his king (Cheshire Cat Chess)? I'm proud of this little gem, and think it might be the first time?
Cheshire Cat Chess (aaru vs. Aganju)

3rd freestyle superchess tournament was won by Edwin Poels with 4-4.
4th tournament is in Zaandam, 13 april. On a 10x10 board...

I'm not very chess minded, can either of these players actually win this game? It's holding up the tourney if not.

Los Alamos Chess (chessik vs. tenuki)

furbster: can't really comment on a running game. (I nearly did...)
Looking at the ratings though, and knowing tenuki, I'd say he should know what he is doing, and he is not known for dragging games out.

Aganju: I remember an strong arbitrator, when told by a player the game was a draw, that he could beat either player with either colour from that position. Probably true as well.

Alain: I am surprised they don't have Dark Chess at a tournament like this. Seems like it'd be the perfect type of game for them to have seeing how they have Poker variants, Chess variants, and Stratego.

Walter Montego: If I understand correctly, this is an event that people attend physically to play chess with an actual chess set, poker with real, physical playing cards and so on. I can imagine certain technical problems playing dark chess over the board... That said, I love the idea of bringing different mind sports together.

pedestrian: I keep waiting for someone to make a Dark Chess program that I can install in my computer to let me play someone. I'd need two monitors hooked to it to make playing easier. You could place them back to back and play directly across from your opponent. Some more programming and a third monitor and you could have kibitzers watch the game with all three views of the board. I'm sure it'd be a simple thing to have a clock running to time the moves.

Michael's Shadow Chess: On each turn, you make 2 "moves". One move is your REAL move. One move is your fake "Shadow" move.

Your opponent will see both moves, but will not know which one if your REAL move, and which one is your shadow move (until after they submit their next move[s]) So your opponent will not know which move is real, and will see both - and will be able to make their REAL and "Shadow" move for their turn. (After they submit and confirm their moves, they will only then see which one of your moves were the real one.)

Other rules:

Pawns can still capture like normal (diagonal / En passant) - even if the "captured" piece ends up being the fake shadow piece, the pawn will still be allowed to stay in the new column.

Checks: Unlike normal chess, you ARE allowed to stay in check, you ARE allowed to put yourself in check & ignore being in check. (your own risk) SO FOR EXAMPLE: Your opponent puts you in check. You can then use your fake move to move your king out of check, and then use your real move to put them into check. So now your opponent will have to decide if they want to try to capture your king, or protect their own king with their real/fake moves.

Walter Montego: Well I'm not the main organiser, but I'll suggest Dark Chess, thanks! The reality is, though, that there is limited space on the schedule, and a desire to concentrate on high quality (and hoopefully popular) games. There are many good games, and chess variants out there like 3-check chess, so you can't do evereything:)

Hope to see you there,
Alain

Alain: I hadn't even heard of this tournament until reading about it here. That'd be an interesting reason to visit England. I'll keep it in mind when I do finally get around to making the trip there someday.

Walter Montego: About dark chess: I would have thought it one game that can only be played at a site like this one, with a computer as an arbiter to show each player the illuminated squares. How could this variant be played on real boards? (I suppose 2?)

rabbitoid: It could be played on real boards. It'd be a hassle, but it isn't unprecedented. That is how Kriegspiel was and is done. Kriegspiel is a game that is over one hundred years old. It is very similar to Dark Chess, but uses checks and checkmates and does not allow moves that are illegal in regular Chess, such as moving into check or castling through check, or moving a piece over a piece.

I have read that the opponents would typically sit in different rooms and require the services of three people to play a game of it. Each would have their own board and pieces, but would put them where they thought the opponent's pieces were. One of the people helping with the game would keep his own Chess board with the actual position on it that neither player could see. Unlike Dark Chess, the players have no way of seeing where their pieces attack or capture except to try the move and learn from what happens. One of the people helping with the game is given the role of referee or arbitrator. He announces if a move is legal or not. A player that makes an illegal move, must take the move back and try another. This is not how Dark Chess is played. It certainly would use the same skills to play as Dark Chess, but you'd have to gain a lot of your information just by what moves are allowed and also choose those moves that might be illegal on purpose to gain such information.

I imagine nowadays someone might have programmed a computer to play Kriegspiel. It seems this game has a following. I read it was used in training to help officers of the Prussian military learn about thinking with incomplete information.

Another superchess tournament!

tangram:surprise winner of 5th superchess freestyle tournament. Robin Wooter "schuli" on brainking won the tournament. Favorite Edwin Poels lost the forst round against Coen Leentvaar "lambik" on brainking and couldnt fill the gap.

The Chess Club (1. December 2013, 12:42:24)
If you´re not a member of my fellowship already, just ask me.

The 10 th superchess championship of the netherlands was held on 28th december in Leiden.

I want shatranj on the site!

Energizer: Shatranj is rather slow game. I would prefer Double Move Chess or Progressive Chess.

andreas: Even better would be to have Bughouse, which is very popular and fun chess variant.

In the following game : Drieschaaks Schaken (gambler104 - Hrqls)

I can end the game by moving my knight from F2 to H3 ... the site doesn't allow this though as my king is in check (by my opponents queen)

I can't find it in the rules though that I should solve a check position if I can finish a game before my opponent actually manages to capture my king?

Hrqls:
The first line says
"This game adds one extra rule to the classic chess."
It is a rule of classic chess that when in check you have to move out of it. Hence resolving your king's check takes priority over moving the knight.

Justaminute: i always understood that in classic check you had to get out of chess otherwise your king would be captured on the next move and you would lose the game anyhow .. the same for a check-mate position .. there is no way to get out of it and win the game, so the game could end right away

in this case i have a way to get out of the check position by winning the game (and thereby preventing any future actions of my opponent) ?

i guess the rules of classic chess are really rules, and not just logical statements :)

Hrqls:
Article 3.9 of the Fide rules of chess say:

The king is said to be 'in check' if it is attacked by one or more of the opponent's pieces, even if such pieces are constrained from moving to that square because they would then leave or place their own king in check. No piece can be moved that will either expose the king of the same colour to check or leave that king in check.

Your movement of the knight would leave your king in check, contravening the rules of chess. Hence I believe Brainking is applying the rules of chess and hence three check chess correctly.

Justaminute: thanks for the quote! it explains it nicely for classic chess indeed!
i am trying to find a position in classic chess in which my king would be in check, but i would still be able to capture the king of my oppenent, but i fear that is not possible in classic chess :)

i will pay more attention next time, and try to remember this game :)

thanks!

Does anyone know if stalemate applies in racing kings? I assume so but am not clear from the rules.

Justaminute: example of a stalemate

Thom27: thank you

A new superchess tournament Will be played on april18th 11:00 in Zaandam, near Amsterdam.

to all combatants!

What happens if one side runs out of moves, but the other side doesn't? Does the latter side win, or is it a draw? Thanks.

tangram:results Open Dutch championship 2017

hello all

tangram: I wish I could come! Sounds like a lot of fun. But travelling ~10000 km... I'll have to pass.

For chess players: although this is Loop Chess, I think this is the most beautiful mate in 4 I ever played. If you know your chess, you will of course recognize the famous pattern.
Starting here: Loop Chess (Aganju vs. Geomomo)

Aganju: I can't say I recognise the combination, even replacing the drops by move-from,, but it's certainly a very good one!

Aganju:

The future of loop chess lies in the hands of this boy. I think the pattern is smothered mate. If not please clarify asap. Thank ye very much.

ketchuplover: yep, that's it - smothered mate.
Thanks!
