Android UCI engine update: Ethereal 8.02 by Andy Grant

A minor update which should not imply an ELO boost. According to the author, the update adds PV tracking feature. I guess Android users will not notice anything different.

Meanwhile, two older versions recompiled by Andy may be interesting for collectors. They were not working at the time they were released. Now the problem is fixed and they both work with Android GUI's.

CEPA 0.5.2 by Javiolo

Javier choosed to release engine binaries in separate apps which install OEX compatible engines. Therefore, the latest release of CEPA feature several improvements on the main GUI features but nothing about engine builds. He's now recommending the installation of the Stockfish engine through the OEX installer that he's updating regularly.

I think such procedure is quite logical and effective.

WHAT'S NEW (v0.5.2 of 26-Jan-17)
- Change Engines, Oex Eng, and Analysis Revised
- Support Android 7
- Sound and Increment to probe no free
See new price
Please update SF to 20170121 release work fine with analysis.

Chess Online 10.0.2 by Miroslav Kisly

This is yet another standalone app to play chess online via an Android device. It comes with an embedded engine for offline play too.

This app is not new to me and it had many updates in the past. The reason for mentioning the last release here is mainly the engine strength which increased since the previous version.

Dedicated chess freaks may install the app from GOOGLE PLAY.

Lichess 4.10.2

Lichess is the Android version of the favorite app of most online chess players. If Lichess didn't show up in Chesstroid until present day, the main reason was that it didn't have its own engine for offline play...

...which appeared to be wrong. Indeed, it had an engine on its own and time controls are available too.

So, meet Lichess for Android at GOOGLE PLAY.

Built for the love of chess, this app is open source and free for all.

Android UCI engine update: Stockfish dev't 8.0.20170113.AP

A new Stockfish build is here to celebrate Aprijal's return. Although he's not as active as in the beginning, his arguments must have been reasonable.

Regarding my own delay to post these beauties, i always have dozens of unreasonable excuses as usual. I'd better skip talking about'em :-)

Nothing compares to a relaxing smile

Hello again in through the dreary "paysage" of this freezing weekend added to the residual fatigue of a couple of hard working days at work, including a 44 hours of sleepless troubleshooting session!

Anyway, who cares about the routine troubles of life?
The following principles are here to help feel better all the time:
-Don't cry, instead laugh,
-Don't surrender, instead stand tight,
-Don't hate, instead love,
-Don't wait, instead act,
And... Especially...
-Don't forget to play chess.
Carry on!

WHAT'S NEW (10-Jan-17):

Beta 13.2:
- A regression in user chat has been fixed

Download latest version from GOOGLE PLAY.

Android UCI engine update: Chiron 4

The new Chiron 4 is about 70 points stronger than Chiron 3, according to the author Ubaldo Andrea Farina. Although it's an update to the engine, the Android app is a different one and will keep Chiron 3 alive on the same device. Interested users can even make two versions play each other the same way as it's possible between Komodo versions.

Chiron 4 costs 2.5 EUR only and the licence checking works exactly like Komodo via Google Play.

WHAT'S NEW (10-Jan-17):

– improved automatic tuning of the evaluation
– improved evaluation of passed pawns, mobility, opposite bishops endings
– improved forward pruning in the search
– improved LazySMP for parallel search
– support for Windows Processor Groups (more than 64 threads can now be used)
– NUMA optimization (new UCI and Winboard options “NUMA”)
– minor speed optimizations
– fixed a pondering bug
– fixed two time management bugs under the Winboard protocol

Chiron 4 is available for Windows and Android.
Buyers of the Windows version will also receive a code to get the Android one for free.

Chiron 2/3 Customers can buy Chiron 4 with a discount through the link they have reiceved. Whoever has bought Chiron 3 in the last month will receive Chiron 4 for free.

Download Chiron for Android on GOOGLE PLAY.

Android UCI engine update: Ethereal 8.01

After Jim Ablett, Aprijal has pushed the pause button too in December. Back in quiet times, we had just a few updates from Javier. That's why i'm happy to see the new version of Ethereal by Andy Grant coming with Android port included in the package.

The last update integrates the hash setting which should add more fuel in the tank. Andy estimated +20 ELO for v8.0. I guess there will be more with the hash feature of 8.01.

The Android port should give around 2400 ELO. I hope it hits 2800 soon, refering to an expression i like: "To believe is half the success".

Chess Tiger 2017.01 for IOS by Christophe Theron

If you own an IOS device like iPhone or iPad, Chess Pro must be on your device. Although the app is not free and costs 10 bucks, i think it pays itself very well for any human player because the engine, the famous legendary Chess Tiger is not bad with multi thread feature (around 2700 ELO on an iPhone 5s). You must be a Top-100 GM to cope with it.

Most young chess fans may not be aware that this engine had topped the computer chess rankings many times before Fruit era, in the 90s. I remember that i've been playing with it on a Palm III, my first PDA on a monochrome screen in 1999. Oh those old days...

Beside the above average engine, the beautiful graphics and user friendly menus make this app on of my favorites on IOS.

WHAT'S NEW (Version 2017.01):
- More customized styles.
- Improved chess engine.
- New friendly features and options.

ChessBase Online ft Stockfish 8

ChessBase has released two minor updates to their app since the introduction of 3.7.1 that featured Stockfish 8. These were labeled and

I guess there's nothing but minor bug fixes not clearly announced by the developers. However, i've noticed that Stockfish builds bundled had different CRC's each time. After analyzing, i've decided they should be based on the same code but with updated compile date. I was curious about a hidden update of Stockfish to a newer version. Apperently not the case.

So can it be that the same engine source code is recompiled with every ChessBase Online build update?

Droidfish 1.66

Following 1.63 posted in Chesstroid, there have been three more updates by Peter. As i didn't write anything about 1.64.and 1.65, let me recover all three for the cost of one.

Version 1.66
- Spanish text to speech support.
- Workaround for Samsung text to speech bug.
Version 1.65
