English 1.c4 e5 (A20-A29). By GM Mihail Marin.
With the move 1.c4, you can avoid some of the openings and lines to be feared after 1.d4. Following 1.c4 e5 – this move order is also called reversed Sicilian – arises an independent opening which, however, still leaves space for many transpositions. To deal with the vast amount of material requires expert skill and great knowledge of the variations, both qualities distinguishing the author, Grandmaster Mihail Marin. The total number of 69,000 games on the CD shows the gigantic field he managed to cover.
