I agree with MSteen... this Kindle book is a revelation for players 1500 or lower... well worth the money... many of these positions look like the ones I find myself mired in in my not-so-picturesque OTB games.
The Tactics Time layout is easy to read and manage. I hope Brennan and Carson find the time to do another one.
Last night I once again started browsing on my Kindle, looking for any chess books that might have shown up. A new (within the last couple of weeks) e-book called "Tactics Time" came up, and I looked into it.
Authored by Tim Brennan and Anthea Carson, it's a collection of 1001 tactical puzzles culled from REAL GAMES by REAL PLAYERS, like the majority of us, i.e., not masters and grandmasters. Nor are the positions composed and organized by theme and motif, as is the case in a number of other (most) tactical books. Brennan has spent years collecting scoresheets from tournaments and playing over the games, looking for tactical shots where the game did (or should have) take a sudden turn.
Now, I've only played over the first few in the book--I'm writing this at 6:21 AM--but I'm impressed already. What really blows my socks off, though, is the BEAUTIFUL layout and appearance of the diagrams! They are large, clear, subtley shaded, and easy to read on both the regular Kindle and my Kindle Fire. One diagram per page, with the solution on the next page.
And here's the coolest part: I solved the first puzzle by putting the bishop on g5. Imagine my surprise when the solution was actually Bb4! At first I couldn't imagine how the bishop could do any good on that square at all. And then I realized that, since it was black to move, black was at the bottom of the board! Of all the hundreds of books and articles I've ever seen, out of all the thousands and thousands of diagrams I've ever glanced at, Brennan and Carson are the FIRST to make this supremely logical step. The side to play is at the bottom, just as it is in every actual game you've ever played in your life. This is great!
The book is only $4.99 at Amazon, and I can't recommend it too highly.
BTW, I'm just a player. I'm not associated with the authors or the publisher or Amazon in any way. I just found it last night and couldn't wait to share.
