   May-27-17 Korchnoi vs Tal, 1962
Nerwal: <Just out of curiosity, how does White win after 49...Qxf6+ and 50...a3, sacrificing the Bd7?> 49... ♕xf6+ 50. ♔xf6 a3 51. e6 axb2 52. exd7 Korchnoi
   May-26-17 Nunn vs J D Tisdall, 1995
Nerwal: ♕ + ♘ pawn vs ♕ is indeed a draw in the general case (here too before the losing ♕d5; ♕d8 or ♕g7 look normal for a human), but in practice the winning rate is very high according to Nunn himself; a database search gave me a winning rate of 55% for ...
   May-24-17 Aleksandra Goryachkina
Nerwal: <Which I always found weird. The discriminatory WGM title is somehow worth more to them. > Not sure it is the main reason. For those who teach chess and/or play often in open tournaments the IM title is probably much more valuable than for those who play in the woman elite ...
   May-21-17 Yifan Hou vs F Vallejo Pons, 2017 (replies)
Nerwal: Not clear it wins, but 37... ♖g4 is interesting.
   May-20-17 Gelfand vs Grischuk, 2014
Nerwal: <what happened if white played 65.Kh3 ?> 65. ♔xh3 d2 and the threat to shield the pawn with ♘d6 wins.
   May-20-17 L Bruzon Batista vs Zhu Chen, 2004 (replies)
Nerwal: <What's wrong with 23...b4?> This may well be better than the game, but doesn't solve all Black's problems after 24. ♘b5.
   May-19-17 Shirov vs Short, 1999 (replies)
Nerwal: <Shirov writes winning the rook with 28. Rge8+ Be6 29. Rxa8 Qxc3 is a win for black. How does that work out?> White cannot defend f2 without losing more material.
   May-19-17 M Vachier-Lagrave vs A R Saleh Salem, 2017
Nerwal: 14... ♗h7 is met by 15. ♗h5 (Δ ♘e6) and 14... ♗g6 by 15. f4. Basically Black has already problems everywhere due to lack of development.
   May-18-17 Adams vs E Inarkiev, 2017
Nerwal: <Why did Adams not play 27 Nxg6 which wins at least two pawns with no visible compensation for Black !> 27. ♘xg6 ♕f6.
   May-18-17 Nakamura vs I Nepomniachtchi, 2017 (replies)
Nerwal: <14...Kf8 seems intended to defend Be7 in case black would play Nd4 but other than that doesn't look too good.> Antoher idea of ♔f8 is that Black can think about taking on g5 and then defend with ♘g8, but in that position it doesn't look too good. (Nunn mentions ...
