We cannot resist the fascination of sacrifice, since a passion for sacrifices is part of a Chessplayer's nature
In the opening a master should play like a book, in the mid-game he should play like a magician, in the ending he should play like a machine.
I can comprehend Alekhine's combinations well enough; but where he gets his attacking chances from and how he infuses such life into the very opening - that is beyond me.
The beauty of a game of chess is usually assessed according to the sacrifices it contains.
