Some of you may have tried this and it’s a smart thing to do: find out how strong you are in comparison with Stockfish 8 (elo about 2600) in terms of chess pieces. In other words how many pieces and which of them the strongest engine can give up to allow you to win the game or to make a draw.
You can do the following: choose menu “Play” – “Play with the machine” – choose drop down list “from position” – click on “board editor” – remove f.ex. the white queen from the board – watch the FEN string: as you’re removing the white queen the big letter “Q” in the string should change to “1”, if this is what happened then everything is fine - mark all the castling options available – click again on “play with the machine” – choose level 8 – choose the black color for yourself – abort and rematch the first 2 games if the game does not start automatically - enjoy.
The amazing side of it is to observe how magnificently it defends and breaks the common stereotypes like “when you’re down material don’t exchange queens”. In fact the opposite could be true: when the queens are off the board you can activate your king and, having a pass pawn, compensate the lack of material. An exciting blitz game I recently played can illustrate this: I blundered a minor piece at an early stage, and my opponent forced me to change the queens. Then I had no other option but to sac the exchange, a whole rook was missing. But for that rook I got 2 connected pass pawns and the active king dominating in the centre– enough compensation for the missing rook! lichess.org/bEmlZbNN/black
