Thanks to Alexei for compiling the latest source code dated 20th of October. As usual, you can modify scorpio.ini before installation to alter the settings to your taste. Arm8 users should bear in mind that they'd better try the standard build and in case of problem they try the build entitled "sl" which includes static libraries for more compatibility in exchange of bigger file size.

Android UCI engine update: Sting 8.9.ACH

Sting is a Stockfish derivative forked from v2.3.1 a long time ago and maintained by Marek Kwiatkowski.

Sting is not made for getting the max ELO but for tactical analysis. However, i still think 8.9 will play stronger than the latest 8.1 made for Android.

8.1 and 8.9 versions were both ported by Alexei Chernakoff. Good news for 64 bit users is that we have an arm8 build this time.

Another update of CorCfish by Alexei.

Description: "CorCfish is an attempt to improve Cfish, in a similar way to what was done with Stockfish to obtain CorChess. Even though the aim may be not extactly the same in detail, the method looks similar. I don't know what the outcome is but you can test it to reveal your opinion."

This build by Alexei Chernakoff comes with static libraries in order to solve issues previously encountered with some processors and Android versions.

If the versions without static libraries work on your device, you don't need this one. The strength is the same and the filesize is bigger by definition.

TCEC-10 is playing with Stockfish dev, Houdini 6 and Fire 6.1!

TCEC Season-10 could finally start this week after a lot of speculations (usually, as always) and some delay.

This time the hardware is a rental monster using high end components like:

-Dual Xeon 2699 v4 – total 44 cores

- Supermicro X10DRL-i

- 64 GB RAM meaning max of 16 GB hash per engine

- 250 GB Crucial SSD

- Windows Server 2012 R2

For Stage 1 the server will be limited to 22 cores, from Stage 2 and for the Superfinal the event will run on the full power of the 44 cores.

TCEC Season 10 participants are:

Andscacs

Arasan

Bobcat

Booot

Chiron

Fire

Fizbo

Fruit

Gaviota

Ginkgo

Gull

Hakkapeliitta

Hannibal

Houdini

Jonny

Komodo

Laser

Nemorino

Nirvana

Rybka

Stockfish

Texel

Vajolet2

Wasp

The stage structure is like the following:

TCEC Season 10 will consist of a preliminary stage, a qualifiers stage, and a Superfinal. Each will have different time controls and structure

Stage 1: this is the preliminary stage, involving 24 engines, playing a single round robin (276 games). The time control of the games will be 60 mins + 10 sec/move. The top 8 engines qualify for the next stage

Stage 2: the second stage will be qualifier of 8 engines with 2x double round robin (112 games) with a slightly longer time control 90 min + 10 sec/move

Android UCI engine update: Ethereal 8.30

Android UCI engine update: armFish 2017.10.04

armFish builds are made by Lyudmil Antonov for arm8 64-bit devices only, using direct cpu instructions via assembly language. It's native and should deliver the fastest builds by definition.

By the way, i've read some posts claiming that some Cfish builds showed faster in some devices. I guess these are related to hardware differences because the lower the level of programming, the bigger the incompatibility problems.

GET armFish 2017.10.04.LA for arm8

Android UCI engine update: SugaR Xpro.1.3.ACH

This version of SugaR has been lately tested and rated by CCRL in their 40/4 rating list, as a Stockfish version. After CCRL released SugaR as the topper of the list, the originality of the engine has immediately generated a lot of discussions in forums.

Some people still think SugaR differs enough from Stockfish code and some others defend that it's just a simple bunch of tweaks by Marco Zerbinati.

I think Stockfish main code is the only independent engine to keep following. But my thoughts won't  keep me from sharing what's available.
