 | | Willem Wallekers: I saw Rh8+ first. Does that make me an artist? |
|
| Dec-17-19 | | saturn2: Nice detail: If 29...Qxg4
30. Qxg4 hxg4 31. Rh5# |

| Dec-17-19 | | Lorenzo69: I am among the 38. g6 crowd. What is the point to lose the Rook? |
|
| Dec-17-19 | | Lorenzo69: I am among the 38. g6 crowd. I did not see the point of 38. Rh8+… Did I miss something? |
|
| Dec-17-19 | | Walter Glattke: It's a profi continuation for a tournament hall, where the audience must be delighted. In club Rooms with only club Players one normally played 38.g6. |
|
| Dec-17-19 | | zb2cr: A Rook sacrifice lures Black a crucial one square away. 38. Rh8+, Kxh8; 39. g6 and Black is helpless. I note that when this puzzle was used last, many people got wrapped around the axle over potentially playing 38. g6. That method also works. Bronstein's method is more elegant. |
|
| Dec-17-19 | | Ja Dood: Just one other thought about g6 versus Rh8+... I am not a very good player. I make mistakes. Given 2 lines which both win, I'll take the one without the rook sac. That way, when I've miscalculated (again) at least I still have that R. Bronstein does not suffer from such foibles of course. |
|
| Dec-17-19 | | Diana Fernanda: Easy,veryfull Easy a8 And continuation g6 |
|
| Dec-17-19 | | Pedro Fernandez: Hey my great <Chris>, I thought you only solved weekend puzzles, but I now see you like solve all the week ones! BTW, why not 38.g6? Warm greetings! |
|
| Dec-17-19 | | Pedro Fernandez: Sorry <Chris>, I see you already named 38.g6. |

| Dec-17-19 | | MrCarciofo: <Nullifidian> I don't understand what you're saying: after g6, Kf8; White must play Rf7+, if Ke8; Rh8#, if Kg8 then Rg8+ and it's as Bronstein's combination. I don't think Bronstejn's move is only flashy: I think it's more cruel because it puts the king in the corner and it shuts him there leaving him waiting just for his death. It's kind of g6 it's more loose of a move. |

 | | An Englishman: Good Evening: For me, the most interesting move of the game consisted of the seemingly humble 5.a3. An undeveloping move that does nothing but prevent ...Nb4, nonetheless after 12.0-0, Bronstein has a lead in development, control of the center and more space, all because of a move that looks more like something Petrosian would have played. |
|
| Dec-17-19 | | Damenlaeuferbauer: After long pondering, the immortal David Bronstein finally found the rook sacrifice 38.Rh8+!,Kxh8 39.g6! and black can do nothing against being mated. |

 | | patzer2: David Bronstein was one of the greatest ever practitioners and teachers of positional chess. His book on the "Zurich International Tournament, 1953" is a classic, must read for those wanting to improve their positional play. In this game, Bronstein's superior positional play is reflected in his domination of the center and the e-file, resulting in the tactics leading to today's easily won Tuesday (38. ?) puzzle. Like Bronstein, I chose the scenic route with 38. Rh8+! for my solution instead of the faster route to mate with 38. g3! P.S.: Black's decisive error appears to be 23...Raf8? allowing 24. g4! ± (a strong attacking positional move) and 24...Qd8? allowing 24. Rfe1 +- (decisively dominating the e-file). Instead of 23...Raf8? 24. g4! ± to +- , 23...Re8 24. Qg3! ± (immediately challenging White's control of the e-file) improves Black's drawing chances. Instead of 23...Qd8? 24. Rfe1 +-, Black can put up more resistance and improve his survival chances of swindling a draw in a technically lost position with 24...Re8 25. Rfe1 +-. Early in the opening, instead of 4...Bf5, I prefer 4...Bg4 as in the drawn game Carlsen vs B Adhiban, 2017. |

 | | Jimfromprovidence: I liked 38 g6 simply because of the mate in one threat it reveals.
click for larger viewThen one discovers that 38...Kf8 does not help black because of 39 Rf7+ and that mate is imminent. |
|
| Dec-17-19 | | TheaN: Hah. I almost immediately spotted the Rh8+ idea closing the net, after briefly discarding g6 as "Black can now put the king aside and run away. Of course not. However, interestingly enough, the Kf8 defense does not work <because> of the combination itself. Ie, 38.g6 Kf8 39.Rf7+ Kg8 (else Rh8#) 40.Rh8+! Kxh8 41.Rf8#. |
|
| Dec-17-19 | | Granny O Doul: Carrots: With 22. f5, Bronstein brought his knight strongly into play, which had been very badly placed for any plan of attacking black's backward e pawn. |
|
| Dec-17-19 | | Momentum Man: Piece activity is very important in chess |

| | RadioBoy: And while you're sitting there thinking about whether to go for the forced mate with rh8 or play g6 first your flag falls. Am I the only one to have ever taken a second to look at an analog clock only to see the flag fall as my hand was moving towards it on the last move of time control? |

| | sjunto: Stockfish has 38. Rh8+ mate in 12; 38. g6 mate in 6. |

| Dec-17-19 | | zb2cr: <RadioBoy: Am I the only one to have ever taken a second to look at an analog clock only to see the flag fall as my hand was moving towards it on the last move of time control?> No, I've had the experience, too. |
|
| Dec-18-19 | | Nullifidian: <MrCarciofo> The reason you don't understand what I'm saying is that you're missing 39... ♖e2 decoying the rook and allowing 40... ♘c7, thus covering the e8 square and preventing an immediate mate. In the two tempi you will now have to waste to capture the knight, bringing the rook to e7 and then capturing on c7, the king can come to f8 and now the position shows why the lack of a second rook is important. If it hadn't been sacced, then it wouldn't matter if the king came to f8 because ♖h8# would mate, but there's no longer a rook on the h-file to deliver mate, so it takes longer. Twice as long, in fact. You have to drag your king in to support the lone rook and either make a mating net with rook and king or grab the g7 pawn and queen the pawn. Either way, it takes a while, whereas 38. ♙g6 creates an immediate threat of mate in one and ultimately is more efficient. |

| Dec-19-19 | | MrCarciofo: !!! Thanks <Nullifidian>! You're right I missed 39... Re2. Thank you very much. Goodnight |
