Notes by Dr. Tarrasch.

1. 7…a6 A very poor move; this and the following one drive the Bishop to his best square. The most natural and the best play is Castling.
2. 9…Nxd4 How many such Scotch games has Blackburne won when he had the first move! and chiefly because the opponents committed this mistake, which strengthens the centre, frees the best square for the Bishop, and costs a move.
3. 14…f6 After P X P, B X Kt follows, and then B x K P. Black has already a very bad game, a consequence of the erratic opening.
4. 18.Re1 White prevents Castling and opens a decisive attack, no matter whether the King moves to the Queen's side or the King's side.
5. 25.Qc2 White continually makes the best and strongest moves.
6. 32.Qxh5 More precise was mate with R to K 7, ch, &c.
