MCEC: An android tournament

[Arzam]

About the Season 3 main event will be delayed because I recieved a lot of new engines, new update version.

I have to test them first to replace their own previous version for the new update version.

also for the engines had aarch64 and dotprod build, I have to play short matches for which builds will be used in the main event.

I am overloaded now but once the initial benchmark finished, I will immdiately test them as much I can.

I have decided to not upload mcec season 1 as serves as testing and also its old data, since other event of MCEC S1 losts.

Better forgot it and focus on this third season instead.

I will keep updating here, MCEC Season 3 Initial benchmark is almost done, I think within 2-3 days from now. I get busy with personal life and goal.

Engine partipants in the incoming testing. The testing is to verify which version or builds will be used in the upcoming MCEC Season 3: The gate keeper.

Note: This is a testing and not part of any MCEC events, Just to show some behind the scene testing of MCEC. This testing is not yet playing!

The Initial Benchmarking is completed:

Due to buggy engines, Chess GUI errors distorted the results as expected.

The event viewed as a baseline of where the engines are ranked, I remove it from part of MCEC Event

[Arzam]

I will also re-introduce MCEC overview for final description of MCEC main overview

The testing of engines above this posts is about to start within this day or tomorrow.

The final starts of "MCEC Season 3: The Gatekeeper" is within the first week of Aug, 2026 most probably.

Note: Due to a lot of engines to test, I choose those engines whom to participate in the MCEC Season 3 The Gatekeeper, in an alternative way of taking them all in a round robin instead of one on one testing them, that is too huge for me even bigger than MCEC event itself and not just that but it will also keep mcec delayed or even trap in an endless testing.

Note: This is the final engines in the test, and it is now currently playing.
The constant changes is due to buggy engines, and As a director of MCEC, I have to adjust to make the starts of MCEC big event tournament ran smoothly.

Stay tuned for futher annoucements or changes and as I said the starts of MCEC Season 3: The Gatekeeper is on the first week of Aug 2026 as I estimated most probably.

Stay tuned.

for information about this testing:

Ursus is removed because the arm64 builds fails to run on CET, so only arm64 v8.2 works. nothing to againts what?

for Lunar has only arm64, dont need to test too.

both Ursus and Lunar will directly play in the Gatekeeper.

for Minic 3.46 both dotprod and arm64 fails to load in CET.

Tcheran 13 and Icarus 1.1.1 is released before I started this testing so Include them.

As cataphract 1.4 stopped working, we downgrade to 1.3.

Stay tuned.
