Sjaak 470 is now available (source and Win32/Win64 binaries for now, I'll add Linux and OS X binaries later today).
I have not tested other variants, but it should not be worse than the odl 399 release for Gothic/Capablanca.

Re: Battle of the Goths 2012 (live broadcast)
If you do that, would it be possible to replay some of the early games with the new version of Sjaak as well? I would be interested in seeing the results of that.hgm wrote:After the Battle of the Goths has finished I will do a gauntlet with Heretic 0.2 versus all playoff partcipants, to get ratings. There is a slight chance I will also be able to add the commercial program Gothic Vortex to that. (If Ed Trice sends me the sources, and I manage to convert it to WB protocol.)

Re: Battle of the Goths 2012 (live broadcast)
Cross table of the second division after three cycles:
It turns out the version of ChessV I am playing is buggy. It is actually a private version, the binary of which Gregory Strong e-mailed me about a year ago. It differs from the last official release by supporting Xiangqi and Spartan Chess and fixed a bug in Knightmate support). But it seems there is something very wrong with it...
At some point (which can be very late in the game) there suddenly appear ridiculous scores, like totally imagined checkmates for one side of the other. And these persist then for a series of blunder moves, until the sddenly fall back to a realistic value. (Which, by that time, is usually between -16 and -32...). The bug does not strike always, which is why id did still score some points against quite strong opponents.
Too bad, because normally ChessV would only be about 50 Elo below Fairy-Max.
Anyway, I started the last cycle of this division now (from the Carrera position). After that we will see the top engines!

Re: Battle of the Goths 2012 (live broadcast)
Final rankings of the Second Division:
Fairy-Max managed to keep the suspense to the very last minute: in the last game it was badly losing against BigLion (at some point it was below -6), which would have meant a 3-way tie for the top position. But both sides still had Chancellors, and at one point BigLion let its guard down, and allowed Fairy-Max to actually get ahead eval wise, by picking off some unprotected pieces while chasing BigLion's King. But BigLion could counter with an uncurable mate threat, so there finally was no choice than to go for a perpetual. The half point was enough for Fairy-Max to finish first place.
Unfortunately the ranking has very little reality value; Sjaak and Heretic played their important games with weak versions, which were later replaced. I used a version for ChessV that later turned out quite buggy, and threw more than half its games. In the games that were spared by the bug, it could play quite strong, so for its opponent's playing it was more or less like flipping a coin whether they would win.
Oh well, better luck next time...
Now I will prepare the round-robin for the playoffs, with the 7 top engines, I hope to start that within an hour or so.

Re: Battle of the Goths 2012 (live broadcast)
You are lucky that you have older versions in git. Before using that for Nebiyu, I introduced a bug that made it hundreds of elo weaker and had an only exe to work with. I had to decompile and compare codes to find out it was a problem with history counters!

Re: Battle of the Goths 2012 (live broadcast)
Couldn't live without version control!
It's really one of those things that I find I can't do without now that I've grown used to it. In fact, I tend to not think of changes as "saved" until they've savely been committed to the repository.

12 out of 13 now and it is going to win again as it seems. It has TJChess on the ropes after the 18th move only!hgm wrote:In the first cycle of the playoffs Bihasa already dealt a devastating blow to all opponents, and leads with 11 out of 12.
I predicted it will have only 1 draw out of 48 games but i was wrong. I guess a loss will come sooner or later although it's not that easy as it seems. In the game against Smirf which ended a draw, Smirf should have won by all means but Bihasa managed a draw.

Re: Battle of the Goths 2012 (live broadcast)
Playoffs after two cycles (Gothic + Capablanca).
In the second cycle, Bihasa again crushed the opposition with 11 out of 12. But this time there was a single loss, showing at least it is not completely invincible.
A bit overshadowed by the Bihasa violence is how much TJchess10x8 has actually been improved compared to the last tourney. If it were not for the newcomers, TJchess10x8 would be very firmly in the lead by now! I must point out that the version 1.1 that is playing here is not yet released, and should not be confused with the latest released version 1.01.
Now a cycle of Bird's Chess has been started.
