Bxc4 a6?! { Hi guys! Ali Hill here with some annotations. Here I believe 4...e6 is more prudent. After ..a6 White can attempt an outright refutation } 5. Qf3! e6 6. Qxb7 Nd7 7. Bxa6?! { Perhaps a touch greedy. Probably ok according to the computer- but as a general rule I would say that when you're a pawn up but behind in development, it's very unlikely to be best to capture a further pawn with a piece that's already been developed. Why not simply bring out the knights and castle, keeping a stable and healthy advantage? Bxa6 opens up further avenues for Black counterplay } (7. Nf3 Ngf6 8. Nbd2 Be7 9. O-O $16) 7... Rb8 8. Qf3 c5 9. Ne2?? { A natural move, but this is not a natural position. Black has sacrificed two pawns for the initiative, and that initiative must not be underestimated. White must be extremely careful in such a position, and look out for all of Black's ideas. The last move, ..c5, was not just pressuring d4 but also introducing the threat of Qa5+ } (9. Nc3 Qa5 10. Qe2! { Very important to hold it together } 10... cxd4 11. exd4 Bb4 12. Bd2 Ne7 13. Bb5 O-O 14. Bxd7 Rb7 15. Bb5 Bxc3 16. Bxc3 Qxb5 17. Qxb5 Rxb5 18. a4 $16) 9... Qa5+ 10. Nbc3 Qxa6 11. O-O Bd3 12. Re1 Bxe2 13. Nxe2 cxd4 14. Nxd4 Ngf6 15. a3 Bc5 16. b4!? { A good attempt to try and get the extra pawns rolling for White on the queenside, but it doesn't quite work in this case. Unfortunately nothing else works either, so White has to improve on move 9 (or move 7) instead. } 16... Bxb4! 17. Nc6 Bxe1 18. Nxb8 Nxb8 19. Rb1 O-O 20. Qg3 Nbd7 (20... Ne4! { Wins much faster } 21. Qf3 Bxf2+ 22. Kh1 (22. Qxf2 Nxf2 23. Kxf2 Qd3 $19) 22... Qf1#) 21. Bb2 Ba5 22. Rd1 Qb7?! { Feels very unnatural. Qe2 looks right here } 23. Ba1 Bd8 24. Qf4 Bc7 25. Qd4 Be5 26. Qb4 Qxb4 27. axb4 Bxa1 28. Rxa1 Rb8 29. f3 Rxb4 { 0-1 White resigns. } 0-1
