Blitzoid chess engine ratings for Android: Update round 8 of 50

After 2816 more games played, 8 positions of Silver opening suite are completed by 89 UCI/XB engines playing each other in 10 divisions of 9 continously.

This means the progress of the project is only 16% so far. But i'm confident the measurement system adopted here is the quickest one for accurate output. Thus, important changes should not arise from now on.

Now i may call this project "THE BLITZOID", bearing in mind i have two others coming soon.

Blitzoid test platform:
* Samsung Galaxy Note II @ 1.6 Ghz all the time (no downscaling)
* 64MB hash where selectable
* 4 cpu threads where selectable
* Own books disabled and replaced by Silver Opening Suite positions (8 of 50 played so far)
* Opening positions played twice with different colors
* Tablebases and ponder off
* GUI: Aart Bik's Chess for Android
* Time control: 5 sec/move

New UCI engine for Android: Fruit Reloaded 2.1

After brand new engine Senpai 1.0,  Fruit Reloaded 2.1 has also found its Android compile. Unfortunately, due to GCC compiler issues, this one can't use multi cores. Shame on my Note2 because the kNps performance will be 3 to 4 times less, which means playing strength will be ~100-150 ELO less for nothing.

The engine works in single core mode under Chess for Android and Droidfish,  my two preferred Android GUIs.

Download Fruit Reloaded 2.1 at: http://www.chessprogramming.net/fruit-reloaded/

Update on 06-May: I've found timing issues in tournament mode under Chess for Android. Unfortunate again, the engine is not certified for my Blitzoid rating list. But good news is that Fruit Reloaded loads very well into another fave GUI Droidfish and plays well using G+X blitz time controls.

Stockfish wins TCEC Stage-2


TCEC 2nd stage has just finished with Stockfish on top. This being not a surprise at all for the dedicated followers, it must be noted that Komodo and Fire were unbeaten while Stockfish lost to Houdini. Houdini lost one game to Komodo and Stockfish won against Rybka which finished 3rd.

The three musqueteers Stockfish, Komodo and Houdini are not alone and comfortable after brilliant performances of Fire and Rybka.

Behind these first five leading engines, Critter, Gull and Shredder are also qualified for Stage-3. However they don't promise any harm for the big five.

Naum and Protector, two surprisingly succesfull players of Stage-1 have both disappointed me with awful results.

And Junior, famous world champion of the past, is now clearly far from dominating the field at 14th place out of 16 engines.

Stage-3 will host first 8 engines qualified and this time a quadruple round robin tournament with both sides of the same opening will assure fairest competing conditions. The first 4 will go to stage-4 and we'll keep missing deep sleeps for a while.

Anand is back for the crown

The 2014 Candidates tournament ended with Anand's victory which without doubt was unexpected for many chess fans after his defeat vs Magnus Carlsen by the end of 2013 and world's second Aronian's peak performance in Zurich.

But surprises are the colour of the beauty and that's why competitions exist. Although Carlsen is still far above from the rest of the world, who knows another surprise is impossible?

Now waiting for Carlsen vs Anand to be revisited in August 2014.

Magma Chess: Nice... but it ain't my fave.

There are more than 100 chess apps in Googleplay for Androiders. Although they are so many to try, very few contain enough juice. We are mostly facing beautiful interfaces, nice boards and very promising developer descriptions.

The truth however, is mostly a lot of ads, too quick levels (some really prefer this and vote one star if the engine plays too strong to beat ?!) and awful moves.

One good example is Magma Mobile's Chess. Everything seems fine until you wanna have a serious chess player in front of you.

There are plenty of levels up to "expert". This expert plays @1500 elo estimated and will not use more than 1 min per move even if you want it to. No time control settings like sec/move or game in x, just child to expert.

The program uses permanent brain too, which drains your battery pretty fast, for an average playing strength. And good news is that it can't be disabled.

I won't include this app in my upcoming rapid swisstroid rating competition which requires 30 seconds/move time control.

I may be reasonable to my oldies like C64's Grandmaster from 80s, but in 2014 a serious chess program should deliver more than cosmetic screen layouts to the enthousiast.

So this one should be great for toy lovers who want to have some fun gor 10 minutes and possibly beat a chess program before going back to Angry Birds.

Magma Chess is also available @ itunes for Apple users. There are paid versions for both Android and IOS in case somebody wants to pay money for exactly the same toy without ads.

I don't.
