Sielecki's fantastic Keep It Simple 1.e4

"So I go there, then he goes there, then I go there, and if he goes there then I GET TO HAND HIS ASS TO HIM!"

With Christof's book you may find that there's no need to spike your opponents tea with laxative, no need to deploy the "annoying humming" manoeuvre (which you immediately deny when an arbiter is called, obviously), no need for the old "obsessive J'adoube tick" to disturb your luckless opponent.

You can win by learning good moves.

Indeed, this repertoire is easy to understand and learn because it - by and large - seeks consistency of theme against Black's responses. Sielecki's prose clarifies so much without being verbose, and the lines are detailed enough without overwhelming the reader. Not only do you have the full content of Chessable's version, Christof has now added fully annotated sample games at the end of each section. I'm hoping he produces the same for his 1.c4 repertoire...

Keep it Simple is perhaps the best book of its kind, and I own more than I care to admit.
