c4 opening

any 1 expalain the idea behind c4 opening. its pros and cons .. does it leads to closed or open game .... does it lead to tactical or positional games ... some books on c4 opening and some main variations

Karpov does a really good book on the english opening so worth reading. Very true that it can transpose and you need to be able to play close postions and open ones.

@ nothing12345 the book is called "How to play the English opening" by Anatoly Karpov. It features 30 games at the top level. Each game has about 20 branch games included in the analyst of the game.
