Greco Defence

The Greco Defence (or McConnell Defence), named after Gioachino Greco (c. 1600 – c. 1634), is a chess opening that begins with the moves:
The opening is categorised by "Encyclopaedia of Chess Openings" as code C40.
Discussion.
Of the several plausible ways Black has to defend his e-pawn, 2...Qf6 is considered one of the weaker choices, since the queen is prematurely and can become a target for attack. Also, the black knight on g8 is deprived of its most natural square. There is, however, no obvious refutation of this opening; White's advantage consists mainly of smoother development.
Although it is a popular opening choice by novice players, it has also been used by players who, according to International Master Gary Lane, "should know better".
