M. Kreuzer vs P. Wolff, 1985
This is a another blog post co-written with Geoff Goodson.
Mini-bio of Martin Kreuzer:
Martin Kreuzer (born July 15, 1962) doctoral advisor was Prof. Ernst Kunz (Regensburg) who was a very strong chess player in his youth in the 1950s. For example, Kunz played for Heidelberg in the chess Bundesliga and in the final of the last "all-German" junior championship (before the GDR closed that down). As a young high school student, Kreuzer played against Kunz in the local league and lost. “That's when I decided to study Algebra with him,” Martin says [1].
After earning his mathematics PhD in 1989 with Kunz, Kreuzer spent two years as an adjunct lecturer at Queen's University (Kingston, Canada). Kreuzer was University assistant at Regensburg University 1991-2000 and got his habilitation in Mathematics in 1997. From 2000-2001 Kreuzer was a substitute professor at the Chair of Algebraic Geometry in Bayreuth, then from 2002-2007 he was the substitute professor at the Chair of Algebra in Dortmund. Since 2007 he is a full professor and holds the Chair of Symbolic Computation at the University of Passau.
In chess, Kreuzer played some international tournaments in the 1990s and got the FM title around 1994 or 1995. But mostly, he concentrated on correspondence chess. Kreuzer became an international correspondence chess GM in 1993. Starting from 1992, he has been playing for the German national team at several Correspondence Chess Olympiads, garnering 3 gold and 2 silver medals over a 30 year period. His CC ELO rating has been above 2600 all this time.
Now he has started to create online chess courses at "Chessable". The first course is called "Mighty Is Geometry". The second course (called "DON'T PANIC - A Chessmaster's Guide to Calculation") will appear soon. Over the board, he plays for two teams (Schachklub Kelheim in Bavaria, Genova Centurini in Italy) and very occasionally in open tournaments.

Mini-bio of Patrick Wolff:
Patrick Gideon Wolff (born February 15, 1968) is an American chess Grandmaster. He is the son of philosopher Robert Paul Wolff and brother of law professor Tobias Barrington Wolff. Wolff won the United States Chess Championship in 1992 and 1995. Wolff also had a distinguished scholastic chess career, winning the 1983 National High School Championship and the 1987 U.S. Junior Championship.
Wolff started at Yale but transferred and graduated from Harvard in Philosophy (1996). He competed regularly in the Harvard Yale Match, which is now named after him.
He was managing director of the $3B global macro hedge fund Clarium but now heads Grandmaster Capital Management, another hedge fund.
Chess advisor Kasparov chose the game Wolff vs Ivanchuk (1993) for the final game in the Queen's Gambit series on Netflix (2020). The actual game was a draw, but Kasparov realized there was a winning strategy and modified the game for the climax.

Better is h4. Before there White knight was on e2, h4 was a risk because Nxg3 would force the recapture with the f-pawn, weakening White’s pawn structure. Now, however, this is not a worry.
13 … Ndf6 14. e5 Ne4 15. Qe3 d5
Now, White can’t take the g5 pawn: 16 fx65 hxg5 17 Qxg5? Because of … h5, threatening the White queen and activating the Black bishop. However, 16 Nh3, which does threaten the g5 pawn, is worth consideration.
- Be1 Bg4
Better is … Nxf4, which wins the pawn: if 17 Nxf4 gxf4 18 Qxf4? h5 is still strong.
- g3 Bf5 18. h3 g4
Better is … gxf4.
- hxg4 Bxg4 20. Nf3
Other moves that look better are c4 or Rh4.
20... Qd7 21. Rg1 Bf8 22. Nh2 Ng7 23. Nxg4 Qxg4 24. Qd3 e6
- c4 Be7
Now, White should play Kb1 or Rh1, instead of this risky capture.
- cxd5 exd5
Black missed 26... cxd5, leaving White’s king on an open file, vulnerable to attack.
- Kb1 O-O 28. Rc1 Rac8 29. Rh1 Qg6 30. Bc2 f5 31. Qa6 Qe6
- Bb3 Kh7 33. Rh2 Rfd8 34. Qxa5 Ra8 35. Qb6 Rdc8
Black needs to drive White’s queen away, but his c6 pawn is threatened, so can’t play Rab8 or Rdb8.
- Qb7 h5
Now … Rab8 deserves consideration.
- Ng1
A mistake, allowing Black to play … Nc3+!, evening up the position. Better is 37. g4.
37... Kg8

Another mistake, as Black missed that move. Now White has a winning position.
