Notes by R. Teichmann.

1. 4…Bb4+ In this variation the Black King's Bishop cannot be well used otherwise; it seems therefore best to exchange it for the White Knight, a course which in other variations cannot be recommended.
2. 8…cxd4 B x Kt, ch, followed by Q to K 2, seems to be preferable.
3. 13.Rhxc1 White has now a very good development.
4. 16…Qg6 Q to B 3 would have been much better.
5. 35…Kg8 With a view to taking the Bishop's Pawn, which he could not do before, on account of Kt x Q B P, R x Kt (!), R x R, Q x P, ch, drawing at least. But he ought to have played the K to R sq instead, after which I find no satisfactory defence for White.
6. 41…fxg4 There was no necessity for taking this Pawn, but even taking it ought not to result in any disadvantage.
7. 44…Qf6 A blunder, which loses the game at once. Black could have drawn the game easily if he simply kept the Queen on the last row; whenever White threatened mate with B to B 5, then K or Q to Kt sq.
