I'd like to join Igel too if that's okay :)

P.S. I sent a request over e-mail for Igel
I've added an account for Igel, you should have received the password by email.
Thanks! Works like a charm! But I need to figure out how to pass engine parameters (Igel is UCI) :)
Probably you will use Winboard/Xboard or ICSDroneng to connect to the server, they all use Polyglot to translate UCI messages to CECP and vice versa. You can set the engine parameters in the Polyglot.ini file.

You can also try to connect your engine to the server via Arena, but I have no idea how reliable this is.
Thanks Joost. To make it easy I simply re-compiled Igel with the built-in parameters. Just to make sure I understand the tourney rules - each of us can you any parameters we want, e.g. a lot of memory and threads, we are not limited by tourney rules?
There are no rules, everything goes, so you are not limited in any way.

Usually I have the parameters of my engine fixed on compile time too, this gives me the least problems.

I used same dotnet construction on hgm's server giving no problems. So something is different.
Maybe something has changed on your end.

I know that you had a bad computer crash several months ago, and that you had to setup everything new on another PC, after this event you didn't play on HGM's server anymore.

The server is online 24 hours a day, usually there are several programs logged in and ready to play, so it should not be too difficult to find out why your program does not respond anymore after playing a single game.
When I try "match …" It complains "tournament variable is not set"
I see that your tournament variable is still set (maybe because you left the server before the tourney was finished), now you can't match players without their tourney variable set.

Just login and type: set tourney 0

This should solve it.

With the command: var - you can see the state of all your variables.
Problem was a missing ''go" command. New server does not use it after first move from opponent. I already did a quick and dirty repair. So looks like it is fixed now in my engine.

I used to use 'go"command to change sides during a game when I was playing against my engine for testing purposes. But that won't work anymore. For current implementation can now handle only one "go" command per game.

If I play against fairy-max with winboard running locally on my computer it still has to work with a go command.
The old server did not send a "go" after the first move of the opponent. A "go" is only sent to start a game where the engine has white. When the engine receives a move (played by the opponent), that move has to be made on the board (if legal) and the engine has to start thinking to find and eventually make a move. See also http://www.open-aurec.com/wbforum/WinBo ... -intf.html (go and MOVE).

Tournament results:

BelFish (Stockfish) won but that was more or less expected.
Schooner is a good runner up.
Nightmare was lucky because Nemorino crashed in an equal looking position.

Spartacus was lucky because Goldbar's opening book (with white!) gave it an instant rep-draw.

We are missing the Raspberry Pi engines for more densely populating the tail of the field.

Bart told me about the rep-draw. I have the same problem, usually it happens once during a tourney, if it is against a stronger player I'm happy but most of the time it happens against weaker players.

Next time I will tell Lisebeth that she should add the Raspberry Pie engines too.

Some of the weaker engines from Folkert were not logged in, in the tournament were AtomBaron, rpiArminius and Micah. Intel atom roughly compares to RPI3 performance wise. I could have added atomNightmare and atomGoldbar, somehow I don't like to play with duplicate engines, even when they are 25 times slower.

I still have an old source of my engine from 20 years back, I'm thinking about adding this, before I can do this I have to add a CECP or UCI protocol, however this has low priority.

I saw Skipper playing badly so I thought I might have played better myself.
But looks like that's not the case. Me playing with white against Skipper. Time control 5 minutes.



So Skipper plays bad but I'm playing worse.

When you play 5 min. blitz against an engine (even if it is weak) you have to play very solid moves, if you play opportunistic moves it will always fire back on you.

When I was still young I was very fond at playing 3 or 5 min. blitz, many times I played over 100 games a day (from the early morning to late in the evening), so I can say that in the past I was an experienced blitz player, but I always found it difficult to beat programs at blitz, programs with ~1800 Dutch Elo (at that time ~1950 Fide) were doable, but anything above got really difficult.
