Notes.

1. 2…e6 Instead of this move we prefer to prepare the advance of P to K 4 by means of Kt to Q B 3. White can continue P to K B 4, and in course of time P to Q B 3 (Stonewall); B to Q Kt 5, with the exchange at B 6, does not give White any superiority. Black will rather be able to utilise his two Bishops. After Kt to Q B 3; 3. Kt to K B 3, might follow B to Kt 5.
2. 4…Be7 Since, in the majority of cases, the Bishop eventually goes to Q 3, it is preferable to make this move at once.
3. 12.Nxd7 It would seem more advantageous either to take Kt at Q B 6, followed by Kt to K 5 or K to R sq, in conjunction with P to Kt 4; P to Kt 4 might even be played at once.
4. 15…Nd8 Black wishes to retain the Knight against the Bishop and succeeds in this.
5. 17.a4 This only weakens White's Queen's side.
6. 22.Bc1 It would have been better to play Q to Kt 4 to force the exchange of Rook after R to Kt 2.
7. 24.Qa4 A blunder. The continuation should have been 24. R to K B 2, followed by B to R 3 or P to B 4, according to circumstances. If 24.... Q X P; then 25. K to B 2.
8. 26…Nxc4 Black has now a considerable superiority in position. White's Bishop is completely hampered.
9. 33…Ra7 To prevent B to K 7 and B to Kt 4.
10. 36.Bh4 White has no moves.
11. 42…Kc2 The Bishop is done for.
