This looks a lot like the game tree/opening book display with which you're already acquainted. For a minute or so it'll look like nothing's going on, but then you'll see the tree view (your former Notation pane) become populated with data
#FRITZ CHESS 15 SOFTWARE#
The software will load the engine and you'll get a dialogue to that effect. "Broad" trees show more alternatives but take longer to generate (it requires more processor time and thus slows down the chess engine). If you create a "Narrow" tree, you won't see many alternative moves displayed in your game tree but the overall process of playing games and generating the tree will be faster. This is similar in some ways to the "Branching factor" in Deep Position Analysis and is another "space for time" tradeoff. The second setting is the "width" of the tree. Rule of thumb: odd numbers good, even numbers bad. Keep in mind, too, that you should use only odd numbers for the search depth, because chess engines tend to develop a tactical "blind spot" when made to analyze at even ply depths. On the other hand, setting a lower search depth means that many more games will be played in a given amount of time, but that the moves themselves are likely to be more superficial. You must realize, however, that there's something of a tradeoff here the higher you set the search depth, the more time the engine will need to make each move - so you're trading time for depth. Remember, the engine is going to be playing a lot of games against itself and storing the moves in the form of a tree, so the search depth is important. For example, if you leave this at "5", the engine will look 2.5 moves ahead before making a move. This controls how far ahead (in half-moves, or "plies") the engine will look before making a move. The first is the search depth, with a default of "5". The next thing you know, something startling happens: the game in your Notation pane disappears, to be replaced by the "Load book" button. To start a Monte Carlo analysis from a particular position, go to the Tools menu, select "Analysis", and then "Monte Carlo" from the submenu (note that this function will be in grey half-tone and unavailable unless you've already loaded a Rybka engine).
