Well, to be honest, I was disappointed. I thought there will be more explanations, more talk, not just brief/basic explanations and exercises/puzzles.

I didn't finished the first book yet.

I bought winning chess tactics and didnt really like it, sold it again. The rest of the winning chess series i got from the library, didnt really like them either. If you look at my rating you can rightfully deduce i havent studied them in-depth tho. I may be partly to blame, but the books also: they didnt inspire me to study them because of the -imo- boring way they are written. I am a lot more enthusiastic about the following three books i have in my possession now: 'The tactics of the end-game' by Jeno Ban, 'How to play chess-endings' by Eugene Znosko-Borovsky and 'Baroque chess openings' by Richard Wincor, which gives me one tacticsbook, one endgame book and one openingbook also containing some full games. I think this is a splendid collection and hopefully I will study those. Sorry to be slightly offtopic..
