etwas besser.}) 8. Ng4 (8. Nd3 Bxc3 9. dxc3 Qxe4 10. Re1 Qh4 11. Qf3 {nebst
Lf4 usw. es ist aber zweifelhaft, ob Weiß selbst in diesem Falle bei
richtigem Gegenspiel mehr als Remis erreichen kann. Die Abtauschvariante des
Vierspringerspiels ist allzu farblos!}) 8... Nxe4 (8... Nxg4 9. Qxg4 d5 10. Qh4

herbeiführen. Die Verwicklungen, die er mit dem Textzug besucht, schlagen
schließlich zu seinem Nachteil aus.}) 9. Nh6+ {Durch diesen überraschenden
Zug kommt Weiß jedenfalls in Vorteil. Für Schwarz wäre es noch am besten
gewesen, den kecken Springer zu nehmen ....} Kh8 ({.... obwohl auch nach} 9...

Dieser Fesselungszug bringt nun den Schwarzen in große Schwierigkeiten.} d5

Schwarz die Wirkung der Antwort 16. Tab1!}) 12. dxe4 d4 13. a3 dxc3 14. axb4

Qe6 $1 (15... bxc1=Q 16. Nxf7+) 16. Rxb2 gxh6 17. Rb3 {Und Schwarz würde den
Bauern h6 nicht halten können. Ich wollte aber dem Gegner die Chance der
offenen g- Linie nicht lassen - zumal die Partiefortsetzung ebenfalls einen
ganz klaren Vorteil versprach.}) 15... Kg8 16. Rb1 {Damit kommt Weiß in
materiellen Vorteil. Schwarz hat nichts besseres zu tun als ungleiche Läufer
herbeizuführen, ....} Rxf7 ({.... da die Variante} 16... bxc1=Q 17. Nxe5 $1
Qf4 18. Nd3 {usw. für ihn noch viel trostloser aussieht. Die Gewinnchance des
Weißen besteht hauptsächlich darin, dass er, abgesehen von dem Mehrbauern,
vier Bauern gegen zwei auf dem Königsflügel hat und der verdoppelte
Mehrbauer des Schwarzen auf dem Damenflügel diesem absolut keine Gegenchance
bietet.}) 17. Bxb2 Qg5 18. Qd3 Be6 ({Verhindert} 18... Bh3) 19. Bd4 {Droht
schon mit 20. Tba1 usw. Schwarz muss nun entweder die Damen tauschten oder den
a-Bauern fallen lassen.} Rd8 20. Qe3 Qb5 {Um vielleicht noch mit der Dame
etwas im Trüben zu fischen.} ({Nach} 20... Qxe3 21. Bxe3 a6 {hätte Weiß ein
ziemlich leichtes Gewinnsspiel gehabt,} {z.B. durch} 22. Red1 Rfd7 23. Rxd7
Rxd7 24. f3 Kf7 25. Ra1 Bc4 26. Kf2 {nebst Ta3 - c3 -c5 und endlich c4}) 21.

später forciert dazu.} Qa4 22. c3 Bc4 23. Bd4 Ra8 24. Qd2 h6 25. h3 Qb5 26.
Ra1 Ra4 27. Qc2 Rxa1 28. Rxa1 Bd3 29. Ra8+ Kh7 30. Qa2 Qh5 ({Falls} 30... Bc4 {
so} 31. Qa7) 31. Qe6 $1 {Das Eingreifen der Dame entscheidet nun in wenigen
Zügen.} Bf1 {Schwarz hat keinen halbwegs plausiblen Zug mehr und
"erfindet"noch diesen unschuldigen Witz.  Jetzt macht Weiß kurzen Prozess.}
32. Ra5 Qd1 33. Kh2 Bxg2 {Noch eine Hoffnung,} 34. Kxg2 ({Denn nimmt Weiß den
Turm} 34. Qxf7 {so wird er nach} Qh1+ {nebst Dxh3+ fx3+ auf e4 mattgesetzt.})
34... Qf3+ 35. Kg1 Rf4 36. Ra8 Rf7 37. Qg4 Qd3 38. Rf8 {SCHWARZ GIBT AUF.

Mit diesem Tausch kommt Weiss dem Ziel einen Schritt nдher; aber was hilft das,
wenn sein Ziel das Remis und nicht der Gewinn ist.} cxd4 {Als Remis
abgebrochen; wieso, warum -- keine Ahnung! Bekanntlich war RemisschluЯ vor dem
45. Zuge verboten. Weiss ist erheblich im Vorteil; die Schwдche des Pa6 ist
sehr bedenklich. Und sowie es ihm gelingt, den Damentausch zu erreichen, ist
der Sieg iemlich sicher. Eine gute Fortsetzung war Qf1-e1-a1-a3. Wenn man
bedenkt, in einer wieviel schwierigeren Stellung Lasker gegen Rubinstein den
Sieg nach und nach erzielt hat!} 1/2-1/2

formation, reaching the conclusion that White's central pawn mass has little
dynamic potential (d3-d4-d5 isn't desirable for White), but it gives White
good control in the centre in the meantime. However in this game White
actually pushed his d-pawn up to d5, gaining space.} 8. Bg5 Qe7 9. Re1 Nd8 10.
