Notes by J. Mason.

1. 6.Re1 Allowing immediate retreat Kt to B 4. Hence 6. P to Q 4 is usually preferred. White has to part with his Bishop for one Knight or the other; and the defence becomes simplified, if not strengthened, accordingly.
2. 20.Re2 This doubling of the Rooks turns out of little use. It would perhaps be more to the purpose to take steps to dislodge one of the hostile Bishops, as an extension of the idea involved in P to Kt 3. From the moment he is compelled to the further advance of his Knight's Pawn, Signor Vergani's position becomes one of increasing difficulty.
3. 22.b4 Apparently based upon a serious miscalculation, or else a downright blunder.
4. 25…Bxa2 Of course. This gift of a Pawn is virtually a gift of the game.
5. 29.Rbxa2 Expediting a foregone conclusion. The explanation seems to be that White overlooked now that his opponent could support the Bishop, and at the same time obviate the danger from the attack of the Knight upon King and Queen.
