1. e4 e5 2. Bc4 Nf6 3. d3 d5 4. exd5 Nxd5 5. Nf3 Nc6 6. O-O Bg4 7. Qe2N 7. Re1 Would have been book. 7... Be7 8. Qe4?! Looking to win one of the undefended pieces but is misguided and gives black too much counterplay 8. Bb5 Ndb4= 8... Nf6=/+ 9. Qe3 O-O!? Sacrificing a pawn for a big attack 9... Bxf3 10. Qxf3 Nd4 11. Qd1= (11. Qxb7? doesn't lead to anything significant 11... Nxc2 12. Qc6+ Kf8-+) 10. Nxe5 Accepting the pawn 10... Nxe5 10... Nd4 11. Qd2= (<= 11. Nxg4 Nxg4 12. Qh3 Nxh2-/+) 11. Qxe5+/= Bd6 12.

A move I hadnt expected in my analysis when giving up the queen I was counting on N move Rxf7 Qxf7 Bxf7+ Kxf7 winning back the queen with an extra pawn 19. Bxb5 I consider ed this a mistake after I played it thinking Bb3 may have been better, but now i think Bb3 would have been likely met with b4 and the c3 knight would be under attack. 19. exf6?! bxc4 20. fxg7 Re8= 19.
