Junior 10.1

Now you can super-charge Dasher and obtain the most reliable analysis from the World Champion "Junior" chess engine. Junior is considered by many to be the strongest and most human-like of all the computer engines. What sets Junior apart is the special search techniques and evaluation functions, giving it a creative playing style and a pronounced understanding of compensation, allowing you to explore new possibilities of sacrifice, attacks and sharp dynamic play.

Junior was written by Israeli programmers Amir Ban and Shy Bushinsky. Despite the goal of the programmers to develop Junior for you, the chess player, it also excels against other chess engines. During the 14th Computer World Championship, Junior impressed experts with its extraordinary dynamic play and remained undefeated during the entire event to capture its 3rd Computer World Championship. In 2007 Deep Junior defeated Deep Fritz in FIDE's "Ultimate Computer Chess Challenge".

Bottom line: Junior is an advanced tool that will give you a new understanding of your games, providing you with the most reliable analysis and showing you the correct plan even in the most complicated positions! Junior 10.1 works seamlessly in your Dasher interface, and best of all, its being made available to ICC members at a huge savings!

The version of Junior you have installed is listed in the top pane.
Score There are many factors that affect score, but the basic scoring method is to assign each piece a value (pawns=1, Bishop/Knight=3, Rook=5, Queen=9) and evaluate which side is winning and by how much. Junior displays the score with + values good for white, - values good for black.
Depth Depth is the ply (1/2 moves) that Junior has searched ahead to produce the current best move and score. A depth of 14 is searching 7 moves ahead.
Time Time is the total time used in the current search to produce score, depth and nodes.
Nodes Nodes is the number of chess positions the engine searched to arrive at the current score and depth.
21. c4 is the move (principal variation) that Junior currently evaluates as the best move for the side to move.
