   Mar-27-17 Robert E Byrne vs Fischer, 1963
sudoplatov: A couple of points about alpha-beta. Given a minimax search tree to a fixed depth, alpha-beta will return the same value (not necessarily the same move) as a complete search. The algorithm works by noting that both sides are trying to minimax their play. A couple of caveats are ...
   Mar-21-17 Curacao Candidates (1962) (replies)
sudoplatov: On my last visit to Curaçao, tried to find the hotel where the Candidates' tournament took place. The names of the hotels in Curaçao seemed to have changed a bit. I did find what I though was correct but there wasn't anything there (except a Curaçao souvenir shop.) The husband of
   Mar-12-17 Lasker vs Pillsbury, 1895
sudoplatov: The reason for d4 rather than d3 is that White hopes to show that the tempo Black gained by putting the Knight on e4 loosens the position too much. After d3 the position is symmetric with White having only the move advantage. It's a lot like the French Exchange or the Double ...
   Mar-08-17 Geza Maroczy
sudoplatov: In my perusing the database for closed polygons, I found another triangle. Maroczy beat Marshall 11-5-8 Marshall beat Pillsbury 5-4-2 Pillsbury beat Maroczy 4-3-7
   Mar-03-17 Keres vs V Mikenas, 1937
sudoplatov: If this is the "delayed exchange" variation, on what move should White take to be an "exchange" or "accelerated exchange" version.
   Mar-03-17 Carl Schlechter (replies)
sudoplatov: There are some interesting chess records involving Schlecter. Marshall +8 -5 =19 Pillsbury +8 -2 =9 Tarrasch +8 -7 =28 Lasker +5 -2 =12 Spielmann +2 -3 =12 Alekhine +0 -2 =0 (Alekhine Marshall +6 -0 =7 triangle) Rubinstein +6 -2 13= Steinitz -4 +3 =3 Capablanca
   Mar-01-17 Spassky vs Ribli, 1980
sudoplatov: This game also shows the first Ne4 (or Ne5) gets the initiative as in the famous Nimzovich-Tarrasch game from 1914.
   Mar-01-17 Spassky vs Tal, 1979 (replies)
sudoplatov: Note that here, as in the Keres-Spassky game, Spassky puts his Queen on c2 and Tal puts his on e7. In this case, e2 was open and the result couldn't have been worse.
   Mar-01-17 Keres vs Spassky, 1955
sudoplatov: The position after 9... c5 is important for the theory of the Queen's Gambit and other opens that transpose into it. Sometimes the same position occurs but with the Black QN on c6. White has e2 for the Queen but Black lacks a corresponding square. The natural square c7 may run ...
   Feb-23-17 Cochrane vs Mohishunder, 1851
sudoplatov: Seems as if Black knew enough to play ...d6 rather than ...d5 in this type of position. Perhaps ...Qf6 was a bit optimistic.
