Subject: Black let White get away with 29. Rd6 in Razuvaev - Lputian ?
I analyzed this game with Sigma Chess and 29... Bc8 should have been
29.... Bxd6
What was black thinking when he did not take the rook?

[Event "URS-ch FL47"]
[Site "Frunze"]
[Date "1979.??.??"]
[EventDate "?"]
[Round "13"]
[Result "1-0"]
[White "Yuri S Razuvaev"]
[Black "Smbat G Lputian"]
[ECO "E09"]
[WhiteElo "?"]
[BlackElo "?"]
[PlyCount "70"]

I have the same game given as
16... h5 17. N2f3 Nce4 18. Ne5 Qe8 19. Bxe4 de4?!
(19... Nxe4 20. Rfe1 with an attack, Razuvaev)
20. Nf5! gf5 21. Qxf5 Rc5 22. b4 Rc7 23. Rd6! Bc8
24. Qg5+ Kh7 25. Nd7! Qxd7 26. Rxd7 Bxd7 27. Bxf6 Bxf6
28. Qxf6 Rxc4 29. Qe7</B > 1-0 (Razuvaev-Lputian, Frunze 1979)

which diverges at move 22 :-(

The version I have came from "The Catalan", Raetsky and Chetverik,
Everyman Chess, 2004, p. 35, where it is mentioned as a sideline
of Raetsky-Gattenloehner (Winterthur 2002). Perhaps the book version
is Razuvaev's opinion about what his _best_ play would have been...

Does anyone have any other information about how Razuvaev-Lputian
actually went ?

Bxd6 Qg5+ Kh7 (Kh8 Qh6+ Kg8 Ng4!) Ng4! and black gets mated. Seems like
these gms are better than sigma chess.
