Welcome to Chess Summer School! Last time out, we had a dazzling and complex attack. I hope you played throught all the lines. Sometimes the king isn't quite castled, but the weak dark squares provide opportunities for the attacker.
This was from Nimzovich-Tartakower, 1911: 1.Qf6 Rg8 2.Bxf7 Qxf7 2...Bxh6 3.Bb3+ Qf7 4.Qxf7# 3.Qd8+ Qe8 4.Qxe8#
