On-line engine blitz tourney October

[hgm]

I'm going to try to make it.

What is the time control and are there any specific server commands that need to be pre-programmed???

TC is 5min + 1s/move.

You won't need any special server commands.

Note that the ranking becomes quite different when I sort the participants by performance rating, rather than game points. This eliminates the luck of the last-round pairing that is intricsic to Swiss. E.g.Joker ended 0.5 point under micro-Max, but scored 122 Elo better:

I'm pleased/surprised with Floyd's performance. This program started one month ago, except for the move generator which is a remote descendent of mscp.

This program is open source. The first release is v0.5, a windows 32bit exe can be found here: https://marcelk.net/floyd/
Sources are on github: https://github.com/kervinck/floyd

Floyd is a very bare-bones program. Just PVS + transposition table + null move and a very simplistic eval. No king safety and no reductions yet. Some of the eval is done in floating point. No pawn table, no material table, no piece/square tables, no killers, no history table, etc. Everything is recalculated again in every node for simplicity.

[brtzsnr]

Nice tournament. Things I need to teach Zurichess:

1. Better time control when pondering move is guessed.
2. End game table bases because in two games it was playing KB vs KP or KB+KN which are draws but the evaluation said >0.
3. King distance to the most advanced enemy pawn.

Hello Marcel,

Perhaps an announcement on the main page?

There are some real chess engine fanatics here...

Later.

[Joost Buijs]

It amazes me that 'NightmareA' running on a humble Atom core has such a good score.

About a week ago I found another bug that has been there for months.
LMR reseach didn't always happen in the PV when running multithreaded.
The problem is that I have a search with a separate SMP part, and when I modify things in the search I also have to modify the SMP part, when I forget this it really messes things up, and this is what happened.
Must be an age thing, I never messed up things so badly in the past.

Anyway, the good result gives me new inspiration to continue working on the engine.

I just can't wait for the next monthly blitz.

[Maarten Claessens]

WaDuuttie gained the third place by snatching an interesting endgame from Crafty in the last round:
[d]7k/7p/6p1/p2Bp3/2Rb4/q7/6PP/3R3K w - - 0 43
Crafty has two pawns and a queen for two rooks, but manages to lose his pawns one by one:
[d]6B1/7R/6p1/p3p1k1/3b4/q7/6PP/3R3K b - - 0 46
[d]R7/4k3/3q2B1/2b1p3/8/p6P/6P1/1R5K b - - 0 72
[d]R7/b1k5/8/8/4p3/7P/B4qP1/R6K b - - 0 80
[d]8/8/2R5/2b5/3q1k2/7P/4B1PK/4R3 b - - 0 112
This makes one wonder about the power of a queen and bishop compared to the power of two rooks and a bishop.

I tried to look at some of the games from yesterday at the ICS, but it seems to store nothing besides the last game in 'oldmoves'.
Is there an option in WinBoard to store ICS games automatically? If there is, I'm overlooking it.
Usually I get my games from other ICS by using 'mailstored', but if there is nothing stored this is not going to work.
Eventually I can put an option in my engine to have it store the games it plays, but I'd rather not do this if it is not necessary.

[hgm]

The ICS should remember the last 40 games of every registered player. The overview can be requested through the 'history' command. With "smoves PLAYER NUMBER" games from this list can be printed, and WinBoard would capture that output and load the game. Which you then can save.

WinBoard automatically saves each game on a file as it finishes when configured to do so through the Save Game Options dialog.

The mailstored command works here too as far as the ICS is concerned. But the ICS just dumps outgoing mail messages in a spooler directory. When I was still running the ICS on a laptop from home I had a script that would periodically look in the spooler directory, and use 'sendmail' on it to distribute it via the stmp server of my provider. But now that I am running from a VPS that doesn't work anymore, and I will have to run my own smtp server.

Last time Folkert was kind enough to explain to me how to do that, but I lost the notes, and do not remember now how to do it. I guess I would really have to get this working again. These will probably be an enormous amount of backlogged mail in that spooler directory, which would all be sent out!
