Notes by R. Teichmann.

1. 6…dxc3 Allowing White to get up a very strong attack; the well-known book move, B to K Kt 5, secures a decided advantage for Black.
2. 7…Qd7 Q to K 2 would be still worse, on account of 8. Kt x P, Kt to B 3; 9. B to K Kt 5, and Black is hopeless.
3. 12.Qc2 Very well played.
4. 12…Nxc4 This is courting disaster; B to K 3 seems to be a valid defence.
5. 14.Rad1 Much stronger than taking the Knight at once; he threatens now P to K 5.
6. 16…Qe7 He had nothing else against the threatened P to K 5.
7. 18…Qxe4 Bold enough, but what can Black do?
8. 26…Rxd6 If he does not give up the Queen, his only alternative is K to B sq, when 27. P to K Kt 3 wins at least the exchange, for if R x R; 28. Q to R 8, ch, K to K 2; 29. Q x R, Q moves; 30. Kt x R.
9. 41.Qe4+ Because after Q x R White wins easily.
