Chess Openings: Theory and Practice, pages 783-784 quotes Keres - Nieman (
sic), correspondence 1934. The game (with commentary) can be found here:
http://www.chessgames.com/perl/chessgame?gid=1286129Horowitz (Euwe?) gives as a black improvement the same line given by Whitehat1963 (Stockfish):
1.g4 d5 2.Bg2 Bxg4 3.c4 c6 4.cxd5 Nf6 5.Nc3 (The reader should see for him/herself why 5.Qb3 cxd5 6.Qxb7 Nbd7 7.Bxd5? loses.)
5...cxd5 (instead of Niemann's 5...e5)
6.Qb3 e6 7.Qxb7 Nbd7 "-/+" (
sic)
"If then 8.Nb5 Rc8!"
Bear in mind that Horowitz's -/+
could mean any of =/+ , -/+ , or -+. But in this case -/+ is probable.
I read somewhere that Horowitz subcontracted this manuscript to Euwe. If true, that would explain why I still like the book so much. IIRC, this was the third chess book I purchased, after Horowitz's
New Traps in the Chess Opening, and Sutherland and Lommer's
1234 Modern End-game Studies.
