Improve Your Chess Tactics: 700 Practical Lessons and Exercises, by Yakov Neishtadt

Improve Your Chess Tactics is an intensive tactics training handbook, with many different themes discussed in detail and a total of more than 700 exercises, at a fairly difficult level. I would say this book is ideal for players in the USCF rating range of ambitious 1600 looking for a challenge to 2000.

The book is in good condition and unmarked, though not without some small signs of wear.
