New engine releases & news H1 2026

[Frank Quisinsky]

"I see I had forgotten to add net archive in the release. I've added it."

Yes, now its perfect.
Sorry for my hint about it.

With syzygy I have problems to load.
I will take a look later this day.

I had a hard night and day ...
1:0 vs. Chess computer Novag Super VIP (tournament game) in the night..
Was a hard fight ...
And 2:0 vs. Verl II, means football ... SG Wattenscheid 09, German League 5
In 4 years vs. Real Madrid at first and Barcelone at second, you will see.
No problem for SG09.

Have to go sleeping now, 07:45 in the morning.
Not good ...

Amira.1.82.exe needs many DLL. How to overcome?
Compile? Yes, it works (VS 2026).

Amira 1.82 is fast and strong, but the structure in a one and only main.cpp is critical.

This has been around for more than one year now but I have just got aware of its existence.

[ehenkes]

Supra 29.1 has a lot of options:

Code: Select all

option name CPU power level type combo default medium var extreme var high var medium var low
option name Deep type spin default 9 min 0 max 9
option name Time control type check default true
option name Time usage type spin default 3 min 1 max 9
option name Search extension type check default true
option name PVS type check default true
option name Turbo search type check default true
option name Positive float filter type combo default auto var off var full var auto var manual
option name Positive float filter level type spin default 5 min 0 max 6
option name Negative float filter type combo default auto var off var full var auto var manual
option name Negative float filter level type spin default 5 min 0 max 6
option name Vertical filter type check default true
option name Lmr type check default true
option name Null move filter type combo default plus var off var normal var plus
option name Temperament type combo default dynamic var dynamic var consistent var positional

option name Memory type check default true
option name Clear memory type button

I dont see Hash or Threads, and it does not work with Cute Chess, stops after some moves.

I dont see Hash or Threads, and it does not work with Terminal or Cute Chess, stops after some (book?) moves. Thus, it is not ready for UCI GUIs.

[ehenkes]

With Own Book false it does not react correctly in CuteChess. Shows wrong time, looses at once.

In terminal:
setoption name Own Book value false
go depth 20
position startpos

info nps 984000
info score cp 69 depth 8 nodes 13538841 pv e2e4
bestmove e2e4

Supra needs a version 30 and more tests.

It seems it is not clear from the thread title: this thread is to announce new engines, not to discuss them. To do the latter, please open a separate thread.

Re Supra:

I think the main issue is not the warnings themselves, but the overall code structure. The UCI parsing looks extremely fragile, which is probably why the engine fails in Cute Chess and on go depth. In its current state, this is not really something other people should be expected to untangle for free. The author should first clean up the codebase and make the protocol handling reliable. After that, it would be much easier for others to help with specific bugs.

At least you could check new engines on basic functions.
