Hello All:
I am going to spend a lot of time with 2 calculation books this summer. Here are the ones I am considering:
1. Beim: How to Calculate Chess Tactics
2. Kotov: Think Like a Grandmaster
3. Aagard: Excelling at Chess Calculation
4. Jacobs: Analyze to Win
...
Tough call. I have 2, 3 and 4 (can't comment on 1. Beim, sorry), but to say I have read them all thoroughly is an overstatement.
But I recommend Kotov first. Not because his examples are easy (they are not), but he was the first to give a systematic method of calculation. Everybody writing on calculation is responding to Kotov, and it is nice to hear it from the old master himself. Btw. the calculation part is just the first half of "Think" (80 pages), you can probably skip the rest.
I also suggest Chs. 1-2 of Tisdall's "Improve Your Chess Now" for a Kotov-critical view, though Kotov deseserves more credit than Tisdall gives him. The Kotov "Tree of analysis" method can be useful in training and in extremely sharp, critical positons on the board.
After that I think Aagaard has on average easier positions than Jacobs, though there are many tough ones in both books. For something a bit easier I like "How To Become A Deadly Chess Tactician" by LeMoir, but do browse it first to make sure it's not
too easy for you.
