- 10…Bd6 Black should play the sounder move 10) .... B—K2, so as not to facilitate the advance of the KP.
- 13…Bc5 Here 13) .... Q—Kt3 was necessary. White would have probably no better reply than retiring the Knight to Kt3, as 14) B—K3 would be met by B—B4. Black could reply first 14) .... Kt—B5 to 14) Kt—Kt3.
- 14.Ndxb5 White ought to be satisfied to gain a move by Kt—Kt3, B—K3 and KR—Qsq, and to weaken the square QB4 for Black; but the combination looked very tempting. Obviously the Knight cannot be captured, as one of the two Black Bishops would be lost.
- 15.Na4 But the hitch is that the Knight has no retreat. If 15) B—K3, P×Kt; 16) Q×Pch, Kt—Q2; 17) B×B, B—R3. If 15) P—QKt4, Black replies 15) .... B—K2 [or Bsq]; 16) P—B4, Kt—Q2; 17) P—K5, P×Kt and wins. Finally 15) B—B4 would be met by 15) .... Kt—Q2.
