   Jun-20-15 Speelman vs S Webb, 1977
 
Virgilio Jacobus: According to "Chess for Tigers", Simon Webb 1978, Speelman played his 31st move immediately, despite having just made the time control at move 30, and offered a draw. Then both players realised that 31...Qd4+ is answered by 32.Nf2 threatening 33.Rd3 and White stands better.
 
   May-24-12 Zukertort vs Englisch, 1883 (replies)
 
Virgilio Jacobus: <poszvald> After 65...a5 66.Ne4+ gains the vital tempo by giving check. The knight then has time to take the f-pawn and come back to stop the a-pawn.
 
   Feb-20-11 Spassky vs NN, 2009 (replies)
 
Virgilio Jacobus: White can soon escape those checks because the black king is vulnerable to a cross-check. For example 59. ... Qe2+ 60.Kf5 Qb5+ 61.Qe5 Qd3+ (or 61. ... Qb1+ 62.Kf6 Qb6+? 63.Qe6+) 62.Qe4 Qb5+ 63.Kf6 Qb2+ 64.Qe5 and again Black is out of safe checks while White is ready to ...
 
   Jan-08-09 Kasparov vs Van Wely, 2000 (replies)
 
Virgilio Jacobus: Loek van Wely is an expert with the Najdorf Sicilian. Even top grandmasters such as van Wely had a hard time playing Black against Kasparov even as late as the year 2000, but playing a highly theoretical opening which they knew very well was a good way of maximising the ...
 
   Aug-13-08 M V Lambshire vs A R B Thomas, 1968 (replies)
 
Virgilio Jacobus: 81.Qa5+ simply picks up the rook. Either there was a time scramble or an error in the recorded moves at that point I guess.
 
   Jun-27-08 M Sebag vs P Smirnov, 2008
 
Virgilio Jacobus: Does Black have good drawing chances after 63...Rg8 instead of 63...Rd3? Certainly many positions with rook and pawn against a queen are drawn and those that are not are in any case very hard to win for the stronger side. As played Black quickly lost the pawn but in my ...
 
   Feb-15-08 Anand vs Carlsen, 2007 (replies)
 
Virgilio Jacobus: Fischer was "unimpressed" when Keres introduced his novelty 11...Nd7 against him at Curacao, 1962, because "Black loses time redeveloping his Knight [to b6] , but the K-side is weakened by its absence and it's questionable whether the Knight is not better where it stands ...
