Good old time book on tactics
Really, all combinatiions involve some type of tactics. And, and combination in particular involves piece capturing. For the novice or mid-level chess player knowledge of all tactics at all phases of the game (books on traps cover tactics in the openings - important to know, books on checkmates cover yet another type of tactic) - all important to know. Though an old book, using descriptive chess notation (which is akward for many), this is still a worthwhile book to consider. The ideas are clearly pointed out and will be helpful for improving your game! Just because a book was written many years ago does not necessarily mean that it will not be very useful!
