This is what some of the critics have to say about
Forcing Chess Moves by Charles Hertan:

"By organizing and explaining the nature of great chess moves
Hertan has brought us all closer to being able to find them."
Former US Champion GM Joel Benjamin

"An intensive training course for advanced players (...) You will
increase your tactical striking powers a lot."
Dr Erik Rausch, Rochade Europa

"When the clock is ticking away, and you have too many viable
candidate moves to choose from, remember Hertan's advice."
Steve Goldberg, ChessCafe

"The categories in this book are quite unusual (...) An ample and accurate collection of startling problems bulging with combinative surprises."
Harold Dondis, The Boston Globe

"The price is low for a volume with so many pages and so much content."
Stephen Dann, Worcester Telegram & Gazette
