The answer is yes.
According to jawp article, a game of Taikyoku Shogi was played for Japanese TV show "Tribia-no-Izumi" (=Fountain of trivia), broadcast on 19th May 2004. The game continued 32 hours 41 minutes and 3805 moves before the first player won. This seems to be the first full-recorded game of the variant.

A very fast checkmate (6 moves) is described here:
1. P-7f P-8d 2. P-5f P-5d 3. R-5h S-4b 4. P-5e Px5e 5. Bx5e P-8e 6. Bx7c+ mate
apologies in advance for everyone who feels insulted because of the use of figurines instead of real Shogi pieces - I couldn't find another analysis board
I'm a Japanese native and have been a chess and Shogi player for a long time.
The Japanese word sabaki basically means proper handling of some complicated task, thus can have different meanings in different fields.
In my opinion, the closest chess term is a "freeing move/maneuver". For example, after 1.d4 d5 2.c4 e6 3.Nc3 Nf6 4.Bg5 Be7 5.e3 o-o 6....
The promotion rule actually matters a lot. With perfect play the game ends in a draw instead of a win for white/gote if you drop the promotion rule. In fact, the evaluation of all four moves in the initial position changes in this way.
I have used two independent methods to get this result in order to double-check that there is no bug in my implementations:
P-2f 2. K-4b 3. P-2e 4. K-3b 5. P-2d 6. R-4b 7. Px2c+ Checkmate
The King is trapped by his own Rook on 4b.
It's a bad idea to have the King and Rook close together or an early mate like this could happen in the worst case
For shogi and xiangqi, the answer is no. There is no analogue for western Chess960 in those chesses. Disclosure: I'm a decently strong player in all three.
The problems Fischer identified in those quotes you gave are that western chess favours the player with more opening preparation, and that there is no room for creativity. (Bear in mind that this is his ...
Your understanding is correct, with one slight adjustment. Instead of thinking about it as "King on a1, Pawn on a2", you should think of it as two things: "King on a1, Friendly Pawn on a2", and "King on a1, Enemy Pawn on a2". The input layer knows the colors of the pieces. Note that I do not say White/Black, but Friendly/...
I am not a Shogi- or Go player (only briefly looked at the games in the distant past), but I am an Aikido instructor. In this martial art the term 'tai sabaki' is one of the fundamental notions. While a literal translation is difficult, in Aikido (and other martial arts) it is described as 'changing the position of the body so as to cause an attack to fail'. ...
I learned shogi from this book. http://www.amazon.com/Shogi-Beginners-John-Fairbairn/dp/4871872017/ref=sr_1_1?s=books&ie=UTF8&qid=1446638715&sr=1-1&keywords=shogi+for+beginners
I bought a shogi set from The Shogi Association (A UK group). The fellow running it at the time (...
It's not a sacrifice, it's a trade after 1. Gxc2 G*b3 and taking the elephant on a3 next.
On the other hand, since doubutsu shogi is strongly solved, you can use an engine/tablebase (e.g. https://github.com/fuzxxl/dobutsu) to set up and see the solution anyway. (I haven't done this, though.)
The first surprise is that if we change the starting position to have mirror symmetry (like western chess) instead of rotational symmetry (like Japanese chess) we get a drawn position in which any lion move is losing.

Randomizing variants of Xiangqi
Xiangqi has numerous variants: here are three which involve randomization.
When I lived in Hong Kong, I saw numerous old guys playing Xiangqi in the villages - while their wives played Mah Jongg back home, I conjectured. About half the time, they would play a randomized version of the game, where all the pieces ...
There was an old chessbase article that presents the shogi board with western chess style pieces.
It links to this introduction to shogi for chess players, which might be exactly what you are looking for.
But I would also second what Tony Ennis is commenting: You'll very quickly get used to the Kanji, it probably makes sense just to accept the slightly ...
One theory that I find reasonable is that the prohibition was originally unique to tsume problems, which makes them more fun, and later re-imported to normal shogi as well.
Another interesting one is a claim that it's implemented to prevent cheating of dropping the hidden 19th pawn to checkmate and immediately stir the pieces to blur it.
To resolve an awkward or problematic position of the own pieces into an acceptable outcome.
This one is bit abstract, so let me try to explain it. The philosophy behind “Sabaki” should mean “please try to utilize all your pieces.”
And Official Guidebook says
"Move your piece which does not work well into ...
In Jiu Jitsu, we practice Tai Sabaki which we are told means "foot placement" or "foot movement". Additionally, in the videogame Persona 5, you befriend a shogi player who teaches you a move called "Koma Sabaki" which allows you to change your party mid-battle. With that information, and being a Japanese speaker, I conclude it most likely means "piece ...
I'm not sure what you're referring to. In shogi, any piece can capture any opposing piece, there are no restrictions like what you're speaking of. Be aware that all pieces capture the same way they move, though. There's no such thing as moving in one way and capturing in another (like the chess pawn, moving forward and capturing diagonally). See the ...
If this discussion is about 打ち歩詰め, one hypothesis is
Betray and kill the king by the lowest rank piece is forbidden when Sengoku Period(Japanese warring period).
And the other consideration is
Since there are 18 pawns altogether from both players, using them for winning spoils the nature of game Shogi.
I am now convinced that Fabian Fichter's answer is correct. The following commentary on Fabian's answer may help to convince others of the same.
1. Position that seems to be impacted by removing chick promotion
Analysing the posted results from the modified Stockfish, all games converge pretty quickly on the following position: S/-l-/ge-/-E-/-LG/cC.
The following starting position is a win in 123 (according to the software I am using):

I don't really know either game that well, but I have played both.
Xianqqi has lots of weirdly place specific rules. For example, the kings are restricted to a 3x3 square in the middle of the board and aren't allowed to move out of it. This makes it hard to do a chess960 type setup for it. On the other hand, with only 5 pawns for 9 rows, the restriction ...
While it is possible to write engines that can play different chess-family games, doing so generally yields an engine that are only "competent" at each one, at best. The best engines for each individual game incorporate specific knowledge and optimisations for that game, and are usually incapable of playing the others.
Many standard chess engines are not ...
I would have to answer no in my opinion. The four forms of chess are different. Shogi from what I remember is a form of chess where capturing an opponent's piece allows you to, at a time of your choosing, put one of that piece on the board as yours. Now that is a level of tactical complexity that surely gives any engine a huge advantage over any strength of ...
The standard dobutsu position gives a win for the second player. It is a well known concept of zugzwang that emerges out of forced lines.
Running Fairy Stockfish (on the pychess variants site analysis section) in the normal dobutsu backrank configuration gives a -9.8 evaluation after running it on a bigger depth.
I know the term Sabaki from the game of Go where it means to make life in an endangered position or to repair a thin position. Maybe this helps to understand the concept in Shogi, too.
In an English language Go book I found the the term resilience as a circumscription of sabaki, and I find it perfectly cromulent.
