I believe that White has a winning position on move 5 of your given line. ( I assume that White's second move is fxe6+). However, White doesn't play 5) Bc3 but plays 5) Qg6+ [I didn't look at 5) Bc3 much so I can't comment on it.] 5) Qg6+ .. A) 5) .. Qg7 6) Qe8 Qe7 7) Qc8 Rb6 [ 7) .. f5 8) gf Qf6 9) Bc3 Qxf5 10) Qe8 +-] 8) Bc3 +- B) 5) .. Bg7 6) Kc2 Ra8 [ 6) ..
