Chess. Sicilian Defense - Max Euwe

The Sicilian defense is established after 1. P4R - P4AD, was already known by Polerio at the end of the sixteenth century, and by Greco at the beginning of the seventeenth, who designated it with the name of "Il Guoco Siciliano".

It is therefore a very old opening and in our days more used than ever; it is the most important defense between semi-open games.
