Notes by R. Teichmann.

1. 6.Bg5 To pin the Knights with the Bishops is, in the Giuoco Piano as a rule, bad, and this is proved again in this game.
2. 8.a3 Another weak move, and loss of time.
3. 9.Bxe6 These ill-judged exchanges seem to be the consequence of his last bad move, as he could not now retire his B to Q Kt 3.
4. 12…Qe8 A very good move, bringing his Queen into action, and enabling him to play Kt to R 4 and B 5.
5. 18.Qg3 A decisive mistake, which ought to lose the game. But there was no more a defence against Black's powerful attack.
6. 21.Nf1 If 21. P to K Kt 4, then R to B 7, threatening Kt to B 5, and winning at least a Pawn.
7. 21…Rxf1+ Black is too eager to simplify the game and reduce it to what he most likely thought an easily won Pawn ending. His two doubled Pawns on the Queen's side, however, ought to have given him some apprehensions about the possibility of winning. Kt to Q 5 followed by R to B 5 would have given Black a won game in a few moves.
8. 31.exd5 Suicidal; he could have forced the draw at once with P to Kt 4, ch, after which we fail to find a winning continuation for Black; e.g.: 31. P to Kt 4, ch, K to Q 3; 32. K to K 2, P to Q Kt 3; 33. K to K 3, P to B 4; 34. K to K 2, P to B 5; 35. K to K 3. White only moves his King, and never exchanges any Pawns; we cannot see how Black can do anything. Clearly he gains nothing by playing the King over to the other side, as the White King is also free, and will always be able to keep the opposition or to block the Pawns. An interesting question arises whether Black, without the mistake on the 30th move, could have won this ending. After a very careful analysis of the position I have come to the conclusion that, in spite of being a Pawn to the good and having the King well in play, Black cannot force a win against the best defence, as the two doubled Pawns can never be dissolved. The following variation shows the resources of the attack and the defence; e.g.—30. ... K to Kt 4; 31. P to Kt 3, K to B 4; 32. P to B 3 (best), P to Q Kt 4; 33. P to Kt 4, ch (best; Black threatened P to Q 5, ch; 34. K to Q 2, P x P, ch; 35. K x P, P to Kt 5, ch); 34. K to B 3, P to Q Kt 3; 35. K to K 3, P to B 4; 36. K to K 2, P to B 5; 37. K to Q 2, P to Q 5; 38. K to Q B 2, and Black cannot win, because, as soon as he plays his King over to the King's side, White would force a passed Pawn on the other, and win.
