The program "explains" the displayed engine variant in text form with completely natural language! It is challenging for a non-title holder to "blindly" imagine what is concretely happening in an engine variant. You see the best move, the rating and that's it.
This version of the program describes in natural text what the variation contains in terms of chess motifs.
For example, in a super-sharp position, a complex variation has the strange rating "0.00". ChessBase 17 then writes "perpetual check" or "positional repetition" and the matter is clear.
Material changes are described vividly: "White wins the queen for rook and knight". "Black loses two pawns". Other examples: "The position simplifies into an endgame TL vs TS".
Exciting are statements like: "White gets a dangerous passed pawn on e6". Or "White sacrifices a bishop", "Black has a penetrating attack", "White gets the majority on the kingside". "Both kings are insecure". "White plays a lever". "Maneuver Sd2-f1-e3-d5."
This makes the motives behind the position clear: the variation can be replayed directly without much clicking:
1. move the mouse arrow to a variant move and the position appears on the main board.
2. alternatively: move the mouse arrow to a variant move, then replay with the arrow keys. The board background turns blue to indicate that you are not moving in the game.
As soon as the mouse arrow leaves the engine variant, the initial position is again on the board and the arrow keys act again on the game continuation.
