Nebiyu Alien is quite strong at mini-Shogi, but it doesn't seem to be aware that in case of repetition white (sente) loses (unless it is perpetual check, in which case the checker loses). E.g.

If you can fix that, I think it would be amongst the strongest engines in the World. We definitely should try to get Takeshi Ito to run it in the 7th UEC Cup (November 24).

They forgot to add the rule to the wiki page
http://en.wikipedia.org/wiki/Minishogi . It says since minishogi is a subset of shogi it inherits all the rules except what is explicitly mentioned there. In other website, it says sente (black) looses not white. Anyway I will figure that out and fix it before November 24th. I will try to contact Takeshi in the shogi forums after that.
Thanks!

Indeed, the Wikipedia omits this. The rules according to which the UEC Cup is played, are published at:

It also does not know the rule about Pawn-drop mates. It is illegal to checkmate by a Pawn drop, both in regular and mini-Shogi. Easiest way to implement this is to not really consider it an illegal move, but as a move that ends the game with a loss. So in Shokidoki, whenever bestScore remains at -INF, and he is in check, I just test if the previous move is a Pawn drop, and if it is, correct the score to +INF (like in a Chess engine you would correct the score from -INF to 0 if you were not in check).

(Note the initial moves with the long thinking times were not played by Nebiyu, but are from the opening line; I created a set of 'test positions' by truncating long-TC games of Shokidoki self-play at a position with near-zero score.)

Btw, can/does Nebiyu support
Big Chess (16x16)? I know some Nebiyus handle 19x19 Go, so there is hope.

Yes it can play it but I have not looked carefully to all the rules. The feature I added in the last version to determine piece values and piece square tables seems to be useful here. It says knight's values is half of bishop's... Anyway here is the game spec.

OK, great! Someone was asking for a Big Chess engine, and the only engine I have that can do boards that big would be HaChu. But since that is basically a Shogi engine it has no provision for e.p. capture.
Btw, just to give you an impression of the relative importance of those mini-Shogi rules: Out of the 160 test games I played, Nebiyu forfeited 14 by repetition, 4 by Pawn-drop mates, and 1 by perpetual checking. I guess it knows that perpetual checking is illegal, (or there would be far more perpetuals), but it probably does not recognize repetitions across captures. This is something I only fixed in Shokidoki just before going to Yokohama as well.

Hello Daniel and H.G.
I started a match between NebiuAlien , but it crashed at the end of each match.
I am not able to provide the log file of Nebiu.
I have a few comments and questions:
Is it possible to avoid that Winboard suddenly closes after the "Fatal Error"?
Can you tell me what to put in the engine parameters for BigChess variant?
What I missed for not having a log file?
Otherwise, here is the WinBoard log file: winboard.debug.gz (257.99KB)

Here are some screenshots:

The number of processors is set centrally in WinBoard, in the Common Engine Options dialog. The hash-tables size as well.

Hi H.G, thanks for the quick reply.
But I had not finished writing my post, I sent in place of the preview. So I re-edited my post.
