   Oct-21-20 P Krueger vs Gruenfeld, 1923 (replies)
rwst: Black plays a solid game here, only maybe 13...Bb4 would have been more active. In the following White does the mistakes. 15.Nd1?! probably the wrong square, better to e2 20.Bc1? why draw back a developed piece, for the aim of possible exchange? Loss of time without compensation... ...
   May-02-19 Maroczy vs G Marco, 1921
rwst: 30...f4 would have prevented some of this but the problems started when Black did not shoo away the bishop with 24...b5 25.Bb3 Nc5. Now either 26.Bc2 or Nf2 Nxb3 and White has not much to show. However Black missed 18...Ng4! (SF/LC0)
   May-02-19 Z von Balla vs K Sterk, 1921
rwst: There is 13...Nb4 14.Bxh7 with Rg4 or Rh8 with chances on the h-file. After 13...f5 maybe Rfb1 or a3? Much earlier White could have played 8...Bb4+ and either 9.Bd2 Qxd4 or 9.Kf1 Bc3 10.Rb1 Bxd4 wins the pawn (SF/LC0)
   May-02-19 Saemisch vs Alekhine, 1921
rwst: 10.exf6 would have introduced some asymmetry Bxf6 11.c3 Bf5 12.h3 and later g4 but it's probably not enough. So where was White too tame? My vote goes to 7.Be2 which could have been 7.Bb5 with Be7 8.OO OO 9.Bf4 a possible continuation
   May-02-19 Nimzowitsch vs Albin, 1905 (replies)
rwst: 20.b4! adds danger on the queenside. Indeed White has not much after 20.Nf5 Bxf5 21.Nxf5 c5 so 20...Nxf5 would be the decisive mistake.
   Jul-24-16 O Zander vs S Gruber, 1922
rwst: Black had possibilities to resist better with 6...d3, 7...Bf5, 8...Ne3, or 21...Nxe3. Then, there were several alternative winning chances for White before Black's big blunder:, 29.d6, 31.Nc4, and 33.h3 but with 33.Qc4? he even allows Black to level. The move that loses the game ...
   Jul-23-16 A Kubbel vs I Rabinovich, 1925
rwst: Many inaccuracies. The opening phase is fine except 8.Kh1?! Black starts to get better when White fails to activate heavy pieces with 15.Qxe2, but 18...Nxc4 19.Nxh5 Nxe3 would have been stronger. Why not exchange as White with 18 or 20.Qxd5 ? Also, 21 or 22.Re1 instead of 22.Bg5 should
   Jul-23-16 J Krejcik vs A Gottlieb, 1922
rwst: Yes after 6...Ke8 it's "only" a bad but playable position. But computers prove that actually 6...Kg6!? is playable too because White won't go perpetual: 7.Qg3+ (7.d4 h6) Kf7 8.f4 Be7 9.Nf3 Nc6 10.fe Rf8 and the king is out of danger AND in the right place. The inaccuracies were of ...
   Apr-10-16 Maroczy vs Bogoljubov, 1922
rwst: Actually White got behind in the opening, the lame 9.Bd2 allows Black to set up a fine, even better position (9.Bb2 OO 10.Rb1 and c4 instead). However 15...Re7 was not good, White on the other hand is not interested in 16.Bg5!, likewise Black misses 16...e4! and 17...Qd6. In the ...
   Jan-18-16 A Schmitz vs L Wei, 2015
rwst: 7...Bd7 already loses a pawn and 10...Qc5 would have lost even more if White had played 11.O-O-O. After 6...Bd6 or 7...Bd6 such things are prevented.
