Giuoco Piano – Attacking with 4.c3 Richard Westbrook, 2006. White can play for an attack at move four 19.Rxe2 Nxf8 with c2-c3 (instead of d2-d3, 0-0, or other 20.Re8 Kg8 move.) It is a time-honored, aggressive line 21.Nd5 g6 which gives the first player good chances. 22.Ne7+ 1–0. Euwe-Jutte, 1927. This lesson explores some of the main lines from White’s perspective and provides 7.Nc3 … sample games. We reach the first important position after the moves: White sometimes plays 7.Bd2 or 7.Nbd2, but the text is the most accurate. 1.e4 e5 XIIIIIIIIY 2.Nf3 Nc6 8r+lwqk+-tr0 3.Bc4 Bc5 7zppzpp+pzpp0 4.c3 Nf6 6-+n+-sn-+0 5.d4 exd4 5+-+-+-+-0 6.cxd4 … 4-vlLzPP+-+0 XIIIIIIIIY 3+-sN-+N+-0 8r+lwqk+-tr0 2PzP-+-zPPzP0 7zppzpp+pzpp0 1tR-vLQmK-+R0 6-+n+-sn-+0 xabcdefghy 5+-vl-+-+-0 4-+LzPP+-+0 7...

White will win the c4-, but the exchanges equalize the position. 8.e5 Ne4 9.0–0 0–0 12.Qh5! h6 10.Qe2 Nc5 11.b4 Na6 This is "Greco's Mate" pattern, but there is no 12.d6 cxd6 mate unless Black blunders. Nevertheless, 13.exd6 Ng6 White wins decisive material. 14.Bg5 Qe8 15.Be7 Kh8 (See diagram, top of next page.) 16.Nc3 Nxb4 17.Rae1 Nc6 18.Bxf8 Qxe2
