| May-18-20 | | Damenlaeuferbauer: After long pondering, the great Slovakian chess player Richard Reti, which most famous games are his wins with the Reti opening against the reigning Cuban world champion José Raúl Capablanca and Efim Bogoljubov 1924 in New York, finally found 18.-,Rd1+! 19.Bf1 (19.Rxd1,Qxc3 -+) 19.-,Qxc3 20.Rxc3,Rxa1 -+. What will remain of him forever besides this two brilliant games are his ingenious pawn ending study and his opening 1.Nf3,d5 2.c4. |
|
| May-18-20 | | saturn2: 18...Rd1+ 19. Bf1 (Rxd1 19 Qxc3) Qxc3 20. Rxc3 Rxa1 21. bxc4 Rxa2 wins material |
|
| May-18-20 | | Once: Interesting. The Rc1 seems to be doubly over-worked. In the opening position, the Rc1 is both protecting the white queen and trying to stop black from playing 18...Rd1+ So black plays 18...Rd1+ anyway. White might try to defend with 19. Bf1. Now the Rc1 is overworked for a second time. He needs to protect the white Qc3 and also the x-ray attack on the Ra1. After Black plays 19...Qxc3, the white Rc1 has to decide whether to play 20. Rxc3 and lose the Ra1 or 20. Rxd1 and accept the loss of his queen. Odd that White's Rc1 was so vulnerable despite being protected twice. And yet Black won with his queen and Rd1 which were both en prise and unprotected. I suppose that shows the value of the initiative over static features in the position. Sometimes. |
|
| May-18-20 | | AlicesKnight: Easy to see from here (even 19.Bf1 loses a R) - more interesting from 2 moves further back; Reti seems to have seen it before that. |

| May-18-20 | | TheaN: The Bf1 defense had me stumped for a while: of course Black uses the overworked rook again. White is best off taking Rd1 immediately but <18....Rd1+ 19.Rxd1 (Bf1 Qxc3 20.Rxc3 Rxa1 -+) Qxc3 -+> Black's queen is too strong in the resulting position. Black has an interesting alternative after 19.Bf1 but loses badly due to weak pawns: 19....Rxf1+? 20.Kxf1 (Qxf1 Qxc3 -+) cxb3+ 21.Kg1 Qxc3 22.Rxc3 ±. The problem is that the queen side pawns are so weak, the bishop can't do much to protect the majority. I would go for the 'practical' 22....bxa2, which leaves Black with at least a passed pawn for the exchange, but White, at any moment, can give it back with a pawn up. |

| | chrisowen: <TheaN> It was in would Bf1 work yes no? |
|
| May-18-20 | | stacase: Earlier I said 19.Bf1 Then what?
Well, 19...Qxc3 that's what, and Rc1 leaves Ra1 unprotected and lost if 20.Rxc3Over the board I probably would have said, "Oh" after a while if White actually moved 19.Bf1 But White threw in the towel and I didn't actually have to look at the position as the game was won. Besides that, puzzle solving at midnight isn't as productive as after breakfast. |

|
| May-18-20 | | zb2cr: The White Rook at c1 is overworked. Black plays 18. ... Rd1+, taking advantage. 19. Rxd1, Qxc3 and Black has Q vs. R.
19. Bf1, Qxc3!; 20. Rxc3, Rxa1 and Black is up by a R. |

| May-18-20 | | Predrag3141: Black overplayed his position. I thought 11 a3 looked strong. I could not get Stockfish to suggest an 11th move, but when I suggested 11 a3 it evaluated +1.06 with 11 a3 Bxc3+ 12 Qxc3 O-O 13 Be3 Qd6 14 O-O Rfe8 15 Rfd1 Bb7 16 Bf3 Bc8 17 Bf4 Qe7 18 cxd5 cxd5 19 Bxd5 Nxd5 20 Rxd5 f6 21 Rc5 Bh3 |

| May-18-20 | | Everett: Funny, I’ve just begun studying this opening from the White side. A Rakhmanov vs Y Vovk, 2015 Rakhmanov played this against Carlsen in Rapids last year A Rakhmanov vs Carlsen, 2019 |

| May-18-20 | | sfm: This is very common, it has occurred in my own games many times. Whenever a queen is covered by a rook on the first rank, look for this. Often exchanges on the rook-covered square obscures the picture, making it easier to miss. The most famous example could have occurred in "the game of the century"
D Byrne vs Fischer, 1956 The position after 20.-,Bb7+ 21.Kf1.
click for larger viewAfter 21.-,Qd7 White resigned, the threat of -.Qh3+ is murderous. So why not play 21.Kg1 instead?

This is totally OK for White - if just not for our theme 21.-,BxB+ 22.QxB,Re1+! After 23.Kf2,QxQ+ 24.RxQ,Rxa1 White ends up much too short of material. |
|
| May-18-20 | | stacase: <thegoodanarchist: Another case of the wrong rook syndrome.> 15.Rfc1
Yup, shoulda been 15.Rfa1 and 18...Rd1+ if it happened would have been 18...Rd1 |
|
| May-18-20 | | Brenin: <Predrag3141>: Another nice line for White after 11 a3 is ... Qa5, when he has the choice between 12 Bb2, e.g. Be7 13 b4 Qb6 14 Na4, or 12 axb4 Qxa1 13 Qe3+ Kf8 14 0-0, with more than adequate compensation for the sacrificed exchange. |

|
| May-18-20 | | Everett: <sfm> I think you mean the Byrne game from 1963, not the one you posted |
|
| May-18-20 | | Predrag3141: <Benin> I had not noticed you made the same comment about 11 a3. I slept in and was late to the party. The difference between 11 a3 Bxc3+ and 11 a3 Qa5 is +1.44. 11 a3 Qa5 12 axb4 Qxa1 13 Qe3+ Kf8 14 O-O Re8 15 Qd4 (to trade off Black's strong queen - worth a pawn compared to Qc5+) Kg8 16 cxd5 Nxd5 17 Bxd5 Bxe2 18 Bxf7+ Kxf7 19 Nxe2 Qxd4 20 Nxd4 h5 21 Be3 h4 22 Ra1 Ra8 23 Nxc6 hxg3 24 hxg3 |

 | | gawain: 18... Rd1+ puts too much pressure on the White rook. The best White can do is to go a rook down. A good tactic. |
