keypusher: <Calli>, let me add my vote to putting this in your Great Escapes collection.
Here are some notes from Lasker's tournament book, interspersed with Shredder comments. The "great escaping" takes place largely between moves 25 and 37, but I include all his notes because they are stylistically interesting and very accurate, though falling short of Lasker's promised perfection.
The first time control was at move 37.
After 5. Bf4: <Not a commendable continuation, as Black cleverly demonstrates.>
After 7. e3: <The complications after 7. Nb5 d4 8. a3 Ba5 9. b4 dxc3 10. bxa5 e5 would result in Black's favour, as White has not time to mobilize his KB and KR.>
Shredder prefers simply 8....Bxc3+ 9. bxc3 e5, when ...a6 will pick up the knight after the bishop moves. 8. Nc7+ is refuted by 8....Qxc7 9. Bxc7 dxc3.
After 7....Nge7: <Excellent. 7....Nf6 would be far weaker, as the QKt would remain unguarded and the KBP obstructed.>
After 13....Qe7: <Black is well developed and the White QBP is weak.
After 16. c4: <Here White ought to have played for attack <a tout prix>. By 16. f4 he would have definitely ruined the Pawn's position, it is true, but he would have opened lines for Bishop and Rook, thus perhaps recovering the lost ground. The White position does not stand finessing, as Black has obviously the superior position, as long as White's QB is shut out at g3.>
After 17. Qh5: <The intention being, after 17....Rfe8 to continue with 18. c5 bxc5 19. Rb7. But Black finds a far better reply.>
After 18. Rfd1: <But now was the time to liberate the QB by 17. Bxc6 Rxc6 18. Qxe5. This omission is taken advantage of by Black in masterly style.>
After 20....Rc5: <Far better than ...Rc7. If White now play f2-f4, Black can reply ...Rfc8, threatening to win a piece by ...Bxd5.>
After 23....Nc6: <White is now badly in need of the displaced bishop. If the KBP was already at f3, White could play Bf2 and Black's attack would not have succeeded.
Position after 25....b5
The dominant motif of the next ten or so moves will be Black's latent threat of a fork on e2, say after 26. cxb5 Rxc3 27. Rxc3 Rxc3 28. Qxc3 Ne2+. Lasker apparently considers this too obvious to point out. He writes:
