    Rybka 4 - Single Processor Version
    USCF SALE IS NOW SHIPPING RYBKA 4!

    For years Rybka has been the uncontested number one in computer chess and since its great breakthrough in 2006 the program has won with remarkable regularity one world title after the other. It is the three-time World Computer Chess Champion, having won its title in Amsterdam 2007,defending it in Beijing 2008, and again in Pamplona in 2009. The SSDF rating for Deep Rybka is an amazing 3227!.

    So that this state of affairs will continue in the future, the Rybka-team gathered around programmer Vasik Rajlich has developed a new version which is even stronger! According to the development team, "Rybka 4 plays more aggressively and more tactically than Rybka 3 or any other Chess program!"

    During the last two years the engine has been improved in almost all areas. One major theme has been the understanding of the attack on the king. The new Rybka 4 is in this case more precise and reliable than its predecessor. At the same time the search function now operates more quickly and efficiently and the evaluation function delivers even more spot-on judgments. As for the playing style, Rybka 4 logically continues the development of the past few years.

    Thanks to further development in the tactical area too, the new Rybka 4 will be indispensable for all those who work and analyze with chess engines. Rybka 4 is delivered with the new user-friendly Fritz 12 interface and contains a database of 1.5 million games and includes CLASSIC membership for playchess.com for one year.

    Rybka, which translates to "little fish", is the shooting star of computer chess. But strength is not everything. Today the main use of chess software is interactive analysis. Rybka's superior playing strength helps you to quickly assess a position. But analysis with Rybka 4 is much more than just evaluations and best moves. In the user interface designed by ChessBase, Rybka 4 introduces several ground-breaking new analysis features:

    Monte Carlo Analysis yields precise evaluations by playing thousands of ultra-fast games in a few minutes in a given position. This is very much like using game result statistics, something human players do when choosing their opening variations. Monte Carlo Analysis can be used in any position, but generally it's most useful in two types of positions:

    Endgame engines often give high scores to drawn endgames (and sometimes low scores to winning ones). Monte Carlo recognises fortresses and other no-progress situations. It's also good in rook endgames, which are another traditional computer problem area.

    Positions where one side has made a big material sacrifice for slow compensation (i.e. not just tactics). For instance you can find lots of piece sacrifices in famous grandmaster chess games which no computer will correctly appreciate and which Monte Carlo gets right.

    Sampled Search gives detailed information about the search process, showing scores and alternative moves in the main line. This is helpful when the program searches for a long time in one position. It lets the users see how the engine is thinking and making its decisions.

    Singular Moves are annotated graphically. This indicates situations where only one clearly best move exists.

    Look for win: whenever you feel that there should be a forced win in a position you can explicitly ask for it. Rybka then searches for a decisive move, considerably faster than in normal analysis.

    Persistent Hash: Rybka can save its hash tables between analysis sessions to preserve valuable information already accumulated in the search tree.

    The author of Rybka, Czech-American International Master Vasik Rajlich, has implemented an extraordinary understanding of dynamic factors into his program. This often results in long-term pawn or exchange sacrifices and an active positional playing style resembling human chess. Rybka scores well in all types of situations but dominates especially in asymmetric positions which arise e.g. from Sicilian systems.

    The success of the program stems from dedicated team work: IM Iweta Rajlich, rated 2417, is the main tester; Jeroen Noomen contributes opening theory and tournament preparation; IM Larry Kaufman develops positional algorithms.

    • Chess Highways - Dejan Bojkov

      Almost all the chess pieces (except for the tricky knights) have the ability to move along straight lines, whether vertically (files), horizontally (ranks) or on the diagonals. These straight lines, which connect different areas of the board and give the pieces the chance to decide the outcome of the battle, are most important in chess, and thus the title - highways. Understanding the abilities of the pieces is absolutely crucial for every player, from beginner to master. In a game of chess you are the general, and the pieces are your soldiers - the better your relationship with your soldiers - the better your results. In his third DVD for ChessBase, GM Dejan Bojkov from Bulgaria gives you an insight into the properties of those pieces which move in straight lines, and tips of how to best exploit the open diagonals, ranks and files to get the maximum out of each piece. In 30 clips you will find out how to better understand your major pieces and exploit the open and half open files; you will learn what their fears are, and how you can help them. The DVD contains at the end a training session to better promote the understanding of the material. It is an invaluable handbook for both chess players and trainers. Video running time: 5 hours 38 min. Dejan Bojkov is a Bulgarian Grandmaster who famously trained Former Women's World Champion Antoaneta Stefanova. An active player, his best results include winning the Bulgarian Championship in 2009 and in 2010 winning the Gronigen Chess Festival. His previous DVDs include the Try the Sicilian Kalashnikov! and A Modern Way to Play the King`s Indian.
