Today I received the analysis of my correspondence ICCF chessfriend Marco Bulgarini where he has a convincing triumph in a correspondence game with other good player playing with the black side the Urosov gambit.
The question is: can the white to improve your position in this main line? We see the game with notations of my chessfriend,

6...Be7 (spanish comment): Me costó decidirme por la línea 6...Be7 en vez de la 6...Nc6, la diferencia está en que con la segunda el negro podía empezar a recibir un ataque por el centro y flanco de rey en el cual exigía una correcta defensa para no caer en desventajas.
(english comment): to play the line 6...Be7 over the line 6...Nc6 was very difficult to me because required many rational-comprehensive decision about the type of position that I would like to me. The main difference that I can to learn that with 6...Nc6 the black required a correct defense to don't lose the game because the white has many attack over the king flank and the center.

12.f4 (spanish comment) Ya estoy empezando a preocuparme, pués tan sólo encuentro dos partidas en la B.D. de Chessbase con más de un millón ochocientos mil partidas. También siento el gusto inicial que también estoy aprendiendo que planes de moda o bien considerados por algún teórico que desconozco, se trae el blanco sobre la cabeza de mi rey.
(english comment): At this moment I was in preoccupation because my public database at the Chessbase site only register two games with this position. I was to learning every time more using the entire variation and I thinked that the white go over my head soon using any theorycal fashioned plan.
12...0-0 (spanish comment) Aquí existía un buen antecedente de algo jugado que descarté por quedar el rey negro expuesto en el centro, si bien aunque el conductor ganó el partido , creo que el blanco pudo mejorar..
(englis comment):here to existed a good foregoing of something played but I discarded it because the black king to met at the center and I thinked that the white position was to feasible to make improves. My smell was good because when during the game I found the urosv chess site of the chessfriend Michael Goeller , he had improves here.
