1. John Hartmann in Chess Life (February, 2018):
“Silas Esben Lund’s Sharp Endgames is a very high-level example of the modern endgame “workbook” described above. About half of Sharp Endgames is wrapped up in its third chapter, “Introduction to Endgames.” This material – covering theoretical knight (3.1), rook (3.2), bishop versus knight (3.3), rook against minor piece (3.4), and queen endings (3.5) – is of the highest quality, and it prepares readers for the real work of Lund’s book.
Each of the 64 exercises in Sharp Endgames – readers are also encouraged to ‘solve’ the 33 examples in chapter three – are designed to be played out against another person or against the computer. Each exercise is coded with a suggested level and time control, and borrowing from the literature surrounding “deliberative practice,” Lund embeds a novel account of 16 subjective features of “critical moments” in his exercise solutions.
Having written on the role of the computer in chess training myself – see US Chess Online for those articles – I cannot speak highly enough of Lund’s work here. Sharp Endgames is the first major title I have seen that outlines a thoughtful strategy for training against an engine, and Lund makes a persuasive case for the practical importance of such activity.
The book is not perfect, of course. The 16 parameters can feel unwieldy and intimidating, and Lund wrongly attributes the theory of “deliberative practice” to Geoff Colvin. (It was Anders Ericsson who popularized it.) I also think it makes little sense to train against a modern engine at full strength when other, ‘lesser’ programs are available. But none of this should detract from what is a deeply original effort, and every player over 2000 should strongly consider the ideas in Sharp Endgames for their own training.”
