   Aug-19-18 Vogt vs Ulf Andersson, 1975
nummerzwei: In his book 'Simple Chess', Michael Stean recommends 31...Nxf4 32.Nxf4 Rc1+ 33.Kh2 Be5 34.Bd2 Rd1? as an easier win: [DIAGRAM] Here 35.g3 hxg3+ 36.Kg2 refutes. Black should play 34...Rf1, but this is not necessarily better than the sequence in the game.
   Jul-29-18 Keene vs E Mortensen, 1983
nummerzwei: <beatgiant> Here one needs to see 44...Rh7 45.Rh1! Rg7/Rf7 46.Rh6 threatening 47.Re6#.
   Jul-15-18 Lapshun vs Paschall, 2003
nummerzwei: <SADDAM: i wonder if 17.b5 is better than the the played a4. With idea to block off the queenside completely and play on the kingside where black has some advantage. Also c6 wouldnt become a target as it did in the game.> 17...b5 18.a4 opening the queenside.
   Jul-10-18 R Praggnanandhaa vs W So, 2018 (replies)
nummerzwei: 48.f4 could be tried.
   Jul-02-18 Spassky vs Petrosian, 1969 (replies)
nummerzwei: In a recent online game, my opponent repeated Spassky's unfavourable opening setup. He only varied with 12.Bd2, by which time White is already slightly worse: [DIAGRAM] In response, I decided to occupy the c4-square: 12...b5 13.Rc1 (13.a4 c6 14.axb5 cxb5 is similar) ...Nb6 14.Be1
   Jun-19-18 Mamedyarov vs Ding Liren, 2018
nummerzwei: The counterplay with 20...b5 and 25...Qb6 while White is gathering his forces on the kingside reminds me of 16...b5 and 17...Qb6 in Geller vs Euwe, 1953 .
   Jun-18-18 D Anton Guijarro vs Smirin, 2018
nummerzwei: I think 14.Nf6+ was indicated: 14...Bxf6 15.Rxd8 Bxd8 (It is possible, but unlikely, that Anton missed something in the line 15...Bxg5+ 16.Rd2 Rd8 17.Nf3, which wins for White) 16.h4 [DIAGRAM] White has now won Black's queen for rook and bishop. Of course, Black can frequently ...
   Jun-09-18 Sax vs Van der Wiel, 1985
nummerzwei: In Arkhipkin - Baikov, Moscow 1988, White went 18.Bd3, got the position after 23.h5 with White to move (!), and, as one would expect in such a sharp position, the extra tempo gave him an easy win with 23.hxg6 etc..
   May-24-18 Salov vs Kamsky, 1995
nummerzwei: The advantage of the bishop pair is often useless if you have a fixed pawn weakness, the reason being that only one bishop can defend it at a time. Here, the pawn structure is symmetrical from 17...Rxb2 to 45...fxe4. Black can quickly train his bishop and Knight at c4, while his ...
   May-09-18 Leko vs Topalov, 1995 (replies)
nummerzwei: <Timman assesses the resulting position as an "elementary win for white". My engine evaluates the same position (after 35. Nd2) as just a little bit better for white.> It seems to me that Timman, while exaggerating, is closer to the truth here.
