Droidfish chess GUI & engine for Android
An amazing app to play with the Stockfish engine on a tablet working with Android.
And it is FREE!!
I love the option to reduce the engine's strength starting from 1% up to 99%
Highly Recommended. Simply the best.

1.e4 Nh6 2.d4 g6 3.h4 c6 4.h5 d5!?
An engine game has been set up between two chess engines, under these conditions:

Players:

1.e4 Nh6 2.d4 g6 3.h4 d5!? 4.exd5
As the position 1.e4 Nh6 2.d4 g6 3.h4 d5!? 4.exd5 doesn't seem to have been played in master tournaments, an engine match has been set up between two chess engines, under these conditions:
Players:
Stockfish 2.2
Strelka 5.1 This UCI engine, by Jury Osipov, was suspected to be a Rybka 1.0 clone an it was banned from engine tournaments, although later some experts studied its code and they found that this was not the case, if my memory supports me correctly. This is a very strong engine indeed.
GUI: Fritz 9
Hardware: ACER Netbook, CPU N270, 1,60HHz, 1GB RAM;
No permanent brain;
Engines hashtable size: 156 MB;
Use tablebases;
Time control: 10 minutes per game plus 5 seconds per move for each player.
Notes:
After each engine move you will fine a few info. For example, if you take Black's 4th move 4...Qxd5 in the first game, you find "1.03 15 33" this means that according to the engine moving, (the evaluation is expressed in pawn units always from the point of view of White) that the program displaying a value of 1.03, it means that it considers the white position to be better by the equivalent of 1.03 pawns. Also the search depth "15 33" tells you how many moves deep the search has progressed. The value is in “ply” or half-moves. The first number gives you the “brute force” depth, the second is the depth to which certain critical lines have been investigated. So the display of “depth = 15 33 ” means that the program has looked at every continuation to a depth of 15 ply (seven moves and a half), while some promising or dangerous continuations are being examined up to a depth of 33 ply.
This is not to be considered a serious match for the following reasons:
A) The hardware used is a slow one;
B) I adjudicated the first 2 games in a won position;
C) For unknown reasons, the last game "stopped" in the middle game position as you will see.
Please feel free to draw your own conclusions on this little experiment. On my part, I just conclude saying that it so much fun to play an early Nh6 move :-))

While we are waiting for Vitruvius 1.0 to be released....

Vitruvius ver. 0.82b is out!
http://deepsaros.jimdo.com/
"This is still an experimental version still keeping a strong positional feature. It is not an engine devoted to play against other engines, but if you choose to let it play against other chess engines, he needs some time of reflection.. The analysis and the need to check possible positional sacrifices require more time than a standard tactical analysis" says its author, in italian language, on http://www.giocareascacchi.it/utility/forum/Chess-Engine/2086-Saros-Vitruvius-.html/5/
THANKS Carotino for this wonderful engine!

A free tool to train and play chess as well
Luca's Chess
The aim is to play chess against the computer with increasing levels of difficulty and with a limited number of hints that are given by a chess tutor.
Also included are thousands of training positions such as different types of endgames, tactical combinations and chess problems (mate in 2,3,4 and more).

Saros Vitruvius: works in progress
Carotino is working on a more human-like chess engine starting from Deep Saros and its name will be Saros Vitruvius.
Here's a link to an interesting discussion for the english speaking friends
http://immortalchess.net/forum/showthread.php?t=11417
and this is a link to a similar discussion in italian language http://www.giocareascacchi.it/utility/forum/Chess-Engine/2043-Il-motore-ideale-adesso-c-e-.html
I can't wait to see an official release of Saros Vitruvius!
THANKS Carotino!

Deep Saros 2.3i available
For Linux & Windows 32 + 64. This is still an unofficial release but it's the most updated version of Deep Saros..
The author says (my translation from the italian language) that: "In the updated version there are little improvements in the evaluating functions (Queen, Knights, Opposite colour Bishops), small improvements in the positional play (read Steinitz), bugs correction and a few "hacks" added."
Here you can read the original italian posts http://www.giocareascacchi.it/utility/forum/Chess-Engine/2018-Deep-Saros-vers-2-3i.html and the download page http://deepsaros.jimdo.com/

LEOpard 0,7c chess engine is born!
It is still an experimental and unofficial version with many limitations, but it works quite well, says its author at http://www.giocareascacchi.it/utility/forum/Chess-Engine/1986-LEOpard-U-C-I-chess-engine-.html
The author goes on saying that it is an "indipendent" engine, meaning that it does not derive from existing engines, although he has staken many ideas and procedures from various open source engines such as
IvanHoe and StockFish. At the moment the engine it is not ready to handle the tablebases, but it should be ready by the end of the summer. On this version there are still some "Deep Saros like" set ups, but they will gradually disappear.
The first official version should be ready within September. At the above mentioned link, you can find either a download link + some games where LEOpard demolishes very strong chess engines at rather long time controls. Enjoy this experimental version, while we are waiting for the official release. Well done Daneel Olivaw! aka....;-))

Recent interview to W. Anand where the chess engine Houdini is mentioned
http://www.chessvibes.com/reports/interview-with-the-world-champio-anand-on-becoming-a-father-kazan-and-more-part-1-of-2/
Interviewer:
(...)
"I want to change the style of the interview a little bit and give you a few quick, brief opposites where you have to choose one. Then you’ll realize that we’ll discuss a few of the subjects a little bit after that, OK? (...)
OK, three: Fritz, Rybka or Houdini?"
Anand: "Houdini."
