from Brisbane, Australia... rating is very old :) Nezhmetdinov, Fischer, Keres are favourites.

   May-15-17 V Zvjaginsev vs Akopian, 2009
 
rwbean: Stockfish 080517 prefers 5. g3 up to 47 ply, then 5. h4 from 48-51 ply, then back to 5. g3 from 51-52 ply (219,000 seconds). Main line goes 5. g3 ♗g7 (-0.29 after 52 ply). Presumably 5. g3 g4 6. ♘h4 f3 is the intention. Stockfish then likes 10. o-o-o (+0.30 at 29 ply) ...
 
   Apr-24-17 Deep Blue vs Bronstein, 1996
 
rwbean: Black gradually threw that away - 46 ... ♔h6 still draws. 23 ... ♖a8 or 27 ... ♖xb1+ would have been decisive.
 
   Mar-04-17 Hamppe vs Meitner, 1872 (replies)
 
rwbean: I put it through Stockfish as well again with at least 8 hours per move ... got 14 ... ♔d8 after 49 ply then 17... b5 after 48 ply 18. d3 after 48 ply 18... bxc4+ after 49 ply 19. dxc4 is forced 19... e4 after 47 ply (although it does like 19... ♖a8 too) 20. ...
 
   Feb-26-17 Ljubojevic vs Kramnik, 1996 (replies)
 
rwbean: White has the chance to swap off an important piece with 22. ♘h5 Black can sac a move earlier with 23... ♘xg4 24. fxg4 ♖xg4 25. ♖e1 ♖xe4 26. ♗a7+ ♔xa7 27. ♘xe4 ♗xe4+ 28. ♖xe4 ♕xe4+ winning
 
   Feb-25-17 A Giri vs Yifan Hou, 2013 (replies)
 
rwbean: With Stockfish150217 and 6 piece table bases, after 63. ♗c8 it plays 63 ... ♖a2+ and it starts failing low after 80 ply - evaluation drops from -2.04 to -14.36 i.e. it sees a win (after about 23,000 seconds on my MBP)
 
   Dec-27-16 Bareev vs Kasparov, 1994 (replies)
 
rwbean: Stockfish 8 seems to think the real mistake is 20. b4 ... giving 20. ♘xc4 ♘f2+ 21. ♖xf2 ♗xf2 22. ♘a2 ♘b6 23. ♘b4 ♖xc4 24. bxc4 ♕xc4 = (37 ply, 353 seconds) versus 20 ... ♗xc3 21. ♗xc3 (-0.60) (42 ply, 4711 seconds) ...
 
   Sep-17-16 P Kostenko vs M Illingworth, 2016 (replies)
 
rwbean: Can white still draw after 45. b4?
 
   Jun-24-16 A Hon vs P Van der Sterren, 1992 (replies)
 
rwbean: Now Komodo 10 suggests 12... f6 is equal. 12... ♗xf3? 13. ♕xf3 is evaluating at +1.83 after 30 ply. 17... ♘e6 is another suggsetion but it's still too late.
 
   Jan-16-16 Smirin vs Bologan, 2015
 
rwbean: 28. ♕c3 is as bad as it looks.
 
   Dec-09-15 Kasparov vs The World, 1999 (replies)
 
rwbean: I got an m4.10xlarge instance on Amazon EC2 (Stockfish 6, 128 GB hash, 40 e5-2676 v3 cores, 5 piece tablebases) and spent another month looking at it - analysis at elvumgar.fea.st. Similar conclusions to last time - 18... ♗d4 is a clear draw, 21 ... f4 is better, it prefers ...
