Dec-19-23 Portisch vs Andersson, 1982    Ulhumbrus: Let us take some brief superficial observations at White's choices after the exchange of queens. 22 Be5 attacks the rook and takes away the squares c7 and b8 from Black. 23 cxd5 isolates Black's c pawn because on 23...exd5 24 Bxf6 shatters the king side. 24 Rc3 defends the b3 ...      Sep-22-23 Botvinnik vs Keres, 1966   Ulhumbrus: It may be that with 9...h5 Keres thinks that Botvinnik's king will become a target but Keres' own king becomes a target instead. However why does Keres think that after 9...h5 Botvinnik's king will become a target? One example of a guess as to an answer is that Keres imagines a ...      Sep-04-23 Fischer vs Geller, 1961    Ulhumbrus: 20 Qb7! improves on an immediate 20 Qb4+ by forcing Black's rook to go to the square d8 first so that after Black replies to the check Qb4+ by ...Ne7 the capture Qxe7+ will fork Black's king and rook as well as winning the knight.      Aug-28-23 Carlsen vs R Praggnanandhaa, 2023    Ulhumbrus: After 12...Be7 White has castled whereas Black has not. On the other hand Black seems a little ahead in development and it may seem that White can gain little apart from dissolving his d pawn by d5. If White has any advantage because of Black's uncastled king how can he make it ...      Aug-23-23 R Praggnanandhaa vs Carlsen, 2023   Ulhumbrus: If after 7 b4 Black can ignore the b pawn 7...Bd6 Two alternative are 7 d3 and 7 0-0. If 8 b5 invites the move...a6 and White is compelled in the end to exchange the b pawn for Black's a pawn instead of Black's c pawn this suggests 8 a3 instead.      Aug-21-23 Carlsen vs N Abasov, 2023    Ulhumbrus: If after 7 d3 Black's c pawns are going to become targets instead of weapons and cannot be made into assets to Black instead of liabilities to Black, one alternative to 7...f6 is 7...c4 returning the pawn whilst White's d pawn is still pinned eg 9 bxc4 f6 If after 9...Ba6 10 g4 is      Aug-16-23 D Gukesh vs Carlsen, 2023    Ulhumbrus: The computer evaluations suggest that 8 e5! gains a slight advantage whereas 8 a3?! leaves White struggling for equality for therest of the game. The computer evaluations suggest ( and the GM commentators may have indicated as well) that 34 Ra2?? is a losing mistake, losing the ...      Aug-14-23 Ivanchuk vs Carlsen, 2023    Ulhumbrus: After 17...Nd8 Black's c pawn is backward whereas White may be able to advance his f pawn. Ivanchuk will want to either advance his f pawn and make his king side pawns, or else to extract enough concessions from Carlsen trying to avoid it. Carlsen will want to try to hinder that ...      Aug-13-23 Carlsen vs Ivanchuk, 2023    Ulhumbrus: In my previous message the word <firther> should read <further>      Jul-17-23 Magnus Carlsen    Ulhumbrus: <visayanbraindoctor > says ( amongst a great many other things) on his page <...The strongest chess players in chess history?...Thus the 1919 version of Capablanca & the 1971 version of Fischer, both of whom played practically error-free chess, are it; updated in opening ...
