perhaps Botvinik did not consider the two bishops to be of unequal value. At
any rate, in his rich experience one can find many examples, in this very
Dutch Defence, where he has won as Black.... with the help of zhe "bad" bishop.

{Der WM-Kampf 1951 in Moskau sah die Begegnung zweier unterschiedlicher
Charaktere: Auf der einen Seite Michail Botwinnik, der disziplinierte, streng
logische, strategische Spieler, auf der anderen Seite David Bronstein, den
inspirierten Schachromantiker. Nach 22 der 24 Partien lag Bronstein mit 11,5:
10,5 in Führung. Botwinnik mußte also, um seinen Titel zu behalten, unbedingt
seinen letzten "Weiß-Aufschlag" durchbringen. Ich stütze mich auf folgende
Kommentare: 1) Salo Flohr in "Von Steinitz bis Fischer" von Euwe; 2) Michail
Botwinnik in "Meine 25 interessantesten Endspiele".} 1. d4 Nf6 2. c4 g6 3. g3
c6 4. Bg2 d5 5. cxd5 cxd5 6. Nc3 Bg7 7. Nh3 {Statt des üblichen 7.Nf3 bringt
Botwinnik etwas Spannung in die Stellung ...} Bxh3 $5 {... und Bronstein
steigt darauf ein. Die Springer sind in dieser Stellung nicht schwächer als
die Läufer.} 8. Bxh3 Nc6 9. Bg2 e6 10. e3 O-O 11. Bd2 Rc8 12. O-O Nd7 (12...
Ne8 $5 {mit der Idee ...Nd6 gefällt Botwinnik und Flohr besser.}) 13. Ne2 Qb6

besser aus.}) 14... Rfd8 15. Nf4 Nf6 16. Qb3 Ne4 {Schwarz hat offensichtlich
keine Probleme.} 17. Qxb6 axb6 18. Be1 $5 {Weiß muss sich etwas verrenken, um
überhaupt noch Gewinnchancen zu haben. Weiß will das Läuferpaar behalten.} (18.

schlechtere Stellung.} (21. Rf2 {(Botwinnik, Flohr) ist besser.}) 21... Bh6 (

etwas besser steht.} (23... Nf5 24. g4 (24. f4 $5 {ist vorteilhaft für Schwarz
(Botwinnik). Die Schwächung des Feldes e4 ist natürlich eine ernsthafte
Konzession des Weißen.}) 24... Nfxe3 25. Bh3 Nxg4 26. fxg4 Bxc1 27. Rxc1 Nd2 {
mit leichtem Vorteil für Schwarz (Botwinnik)}) 24. Kf1 Bg7 25. g4 {Weiß
gewinnt Raum am Königsflügel.} Nc6 26. b3 $6 {Jetzt versucht Botwinnik,
ebenfalls am Damenflügel Raum zu gewinnen, aber der Aufzug der Bauern führt
lediglich zu einer Schwächung.} (26. Rc2 $5 {mit Verdopplung auf der c-Linie
sieht vernünftig aus.}) 26... Nb5 27. Ke2 $2 (27. a4 {ist besser, um die
folgende Möglichkeit zu unterbinden.}) 27... Bf8 $6 ({Hier konnte Schwarz} 
27... Na3 $1 {spielen. Botwinnik meint, dass Schwarz dann sogar etwas besser
steht. Der Na3 ist in der Tat recht lästig. Schwarz kann weiter ...Bf8-d6
nebst ...Rc7, Rdc8 spielen.}) 28. a4 Nc7 29. Bg3 Na6 30. Bf1 f6 31. Red1 Na5 {
Die Stellung ist ausgeglichen, Weiß muss sich um den Pb3 kümmern.} 32. Rxc8
Rxc8 33. Rc1 Rxc1 34. Nxc1 Ba3 35. Kd1 Bxc1 $6 {Schwarz gewinnt einen Bauern,
löst aber sein Blockade des Damenflügels auf. Bronstein begibt sich langsam
aber sicher auf die Verliererstraße.} (35... Kf7 36. Kc2 (36. Bxa6 bxa6 37. Bc7

Weiß hat trotz Minusbauer die Initiative übernommen. Die schwarzen Springer
sind zur Passivität verdammt.} f5 $2 {Öffnet die Stellung für die weißen
Läufer. Stattdessen hätte Schwarz stillhalten sollen.} 40. gxf5 gxf5 41. Bd3
Kg6 (41... Kf6 $2 42. Bh4+ {nebst Bd8 (Flohr)}) 42. Bd6 $2 {Dieser Zug war der
Abgabezug. Trotz 20minütigem Nachdenken konnte Botwinnik nicht entscheiden, ob
dieser Zug oder 42.Bb1 der bessere Zug ist. Erst in der häuslichen Analyse
konnte er sich überzeugen, dass er den falschen Zug abgegeben hatte.} (42. Bb1
