The F3 problem is too great for this to be a good game. I hate to rate a game 'poor', but if not fixed,that problem kills the game.

Builder chess. Introducing the Builder. (8x8, Cells: 64) [All Comments] [Add Comment or Rating]

Moving the rook is a clever move, as it prevents mate. The king would still be checked, though. Double-checked. A more clever move is the one listed on the main page, I think. The reason: You prevent check on the next move and you prevent mate. I don't know, but I think it is more clever than Re6.

Anyway, the situation on the main page was just to show how builders take and how they mate/check.

One possible notation for the builder: The Builder (Bu or I), builder take: Id5-a5*(b)Ra6->(w)Ra6. The builder (I) on d5 moves to a5 and takes a (black) rook on a6, switching it to (->) a (white) rook on a6. For the situation in which the black rook moves to e6, the builder does this: Id5-d6*(b)Bd7 -> (w)Bd7+ &*(b)Re6 -> (w)Re6+. This means that the builder on d5 moves to d6 (Id5-d6) and kills (*) the (black) bishop on d7 switching it (->) for a (white) bishop on d7, checking, AND (&) it kills the (black) rook on e6, switching it for a (white) rook on e6, checking.

To make it clear, in the situation above the builder must be positioned so that in one move it can become adjacent to the king, in order for it to be in check. No move other than Kd8 is possible in order to get out of check. Any attempt to block the builder won't work because:

a) if the rook tried to block the builder, it could still switch the black bishop for a white, checking the king, and

b) if the bishop moved at all, the builder would simply take the king, thus any attempt to move the bishop would be illegal.

This makes the builder way to powerful. An interesting variant would be to have an anti-king instead of a king.

Another thing I've been thinking about is what happens if a piece moves adjacent to a builder? Is that suicide or does nothing happen at all? The latter would make it impossible for a builder to capture another builder, is that good or is that bad?


💡📝Hafsteinn Kjartansson wrote on Sun, Jun 12, 2011 03:47 PM UTC:
First, if the builder was at d4 the king wouldn't be in check.

Your idea of the builder not being able to check is interesting and would help this piece to become 'even', so to say. The movement seems a bit strong to, I already added a suggestion on the main page.

💡📝Hafsteinn Kjartansson wrote on Sat, Jun 11, 2011 10:52 PM UTC:
No. Remember: The builder changes the opponents pieces to your pieces. The builder could still move adjacent to the bishop, exchanging it for your bishop, checking the king.

I like the approaching idea! And I wasn't aware of the builder being like the fire demon...

💡📝Hafsteinn Kjartansson wrote on Wed, Jan 12, 2011 02:48 PM UTC:
Good idea!
But I still think some restrictions on checking/mating would be needed. Any ideas?

💡📝Hafsteinn Kjartansson wrote on Thu, Jan 6, 2011 03:19 PM UTC:
Good question. My idea was that it should become a pawn again, exchanging with the opponent's pawns:

But your idea's good, too.

By the way, the builder is a very strong piece. I'm working on some restrictions to make it fit better in FIDE chess. I'll post them here soon.

One suggestion: Make a game on a bigger board (10x10, 12x12 or something like that) and with some restrictions on the 'combination pieces' ; a piece may only merge with one piece, two pieces etc., add some pieces like the dabbabah, the alifil etc, make the queen only accessable with merging, add a man (non-royal king) instead of the queen et cetera...

Some of the combined pieces look a bit to complicated to me. I'd like some diagrams to help me understand these pieces. I agree with Tim, the pegasus sounds simply too strong. But I still like this idea, and would like to play it. I'm out looking for extra pieces...

XSChess. Xiangqi plus shogi plus chess. (9x14, Cells: 126) [All Comments] [Add Comment or Rating]

Daniil, 
I'm glad you asked. Yes, pawns do promote although I forgot to mention it. Their promoted form is the gold, as in Shogi.
The idea about the XS-chess pawns is that it is the shogi pawn (straight forward, capturing as it moves, promoting to gold), the xiangqi pawn (straight forward, captures as it moves, can move and capture one sideways upon crossing the river) and the chess pawn (one squere forward, captures one diagonally, can move two squeres forward on it's intial move. Can capture En-Passant forward (as the chess pawn only can move forward)). That becomes the XS-chess pawn: Moves one squere straight forward (all variants), captures as it moves (xiangqi, shogi) or one squere diagonally forward (chess), can move and capture one squere sideways after it crosses the river (xiangqi), can move but not capture two squeres forward on it's intial move (chess), promotes to gold (shogi) and can capture En-Passant forward only (chess) as the xiangqi pawn (who can move sideways after crossing the river) can never move two squeres at once, only the chess pawn can (and only forward). As pawns can move sideways after crossing the river, they can always move, no matter what. All those 'extra effects' makes the XS-chesspawn much more powerful than normal chesspawns, normal shogipawn or even normal xiangqipawn! I still say it is worth one point but in fact it should be three or four points...

I love this game! I've played it on Icelandic (where it's name is Hrókurinn, meaning 'the Rook' ) along with my friends. It is wery fun!!! Best of all is the different types of game modes you can choose from. Or you could just make up your own, which (should be) easy.
