Best Combinations of 2015 - Quarterly Chess Tactics – Volume 3 is now out with over 500 puzzles for you to solve. It is available on Amazon and on Kobo. The Kindle free sample contains dozens of combinations, so you can first practice those positions and see if you like the selection. This publication is a collection of over 500 best combinations played by strong chess players in tournaments that took place the third quarter of 2015. I first filtered the correct combinations with various computer-assisted approaches, and then manually went through the entire collection to select only the puzzles useful to practical chess players.
As criteria for including the games into this book - I used Mikhail Botvinnik's definition of a combination, which defines it as "a forced maneuver or maneuvers combined with a sacrifice, as a result of which the active side gains an objective advantage." Finding such combinations is typically the most useful type of exercise for those who want to sharpen their tactical skills.
