| Jul-21-18 | | Walter Glattke: 32.Nxa6 got other continuations. |
|
| Jul-21-18 | | hdcc: For me the same as CHC and AW: 26...Re1+ 27. Kf2 c3 ... I ran it through Stockfish; at 19-ply the text move is -1.59, whereas c3 is -0.67. |
|
| Jul-21-18 | | mel gibson: The first few moves were obvious.
Stockfish 9 agrees with the first 6 plies:
26. Nc6
Re1+ (26. .. Re1+ (♖e8-e1+ ♔g1-f2 ♖c8-e8 ♘c6xb4 ♖e8-e2+ ♔f2-f3 ♖e2xb2

score for Black +2.47 depth 39. |

| Jul-21-18 | | mel gibson: Lesson here -
never leave your Rook trapped in the corner -
develop all your pieces. |
|
| Jul-21-18 | | Cheapo by the Dozen: Black was slightly down in material, and the simple defense of 26 ... Bc5+ wasn't terribly appealing. By way of contrast, the first four actual game moves win a pawn and give Black a dangerous pawn-pushing attack, because Black recovers the sacrificed piece. I worked all that out pretty straightforwardly. I was then planning to simply take the knight, which the engine confirms also gives Black a nice advantage, so I'll count that as one of my rare Saturday puzzle solutions. :) |

 | | agb2002: Black has a rook and a pawn for two knights.
White threatens Nxb4 and Nxa7.
The first idea that comes to mind is 26... Re1+ 27.Kf2 c3: A) 28.bxc3 Bxc3
A.1) 29.Nxa7 Bxa1 30.Kxe1 (30.Nxc8 Rxb1 - + [r vs N]) 30... Rc1+ 31.Kd2 Rxb1 - + [r vs N]. A.2) 29.Nxc3 Rxa1 30.Nxb4 (30.Nxa7 Rxc3 wins) 30... a6 31.Nbd4, unclear. B) 28.Kxe1 cxb2+ 29.Nxb4 bxa1=Q wins decisive material. C) 28.Nxb4 cxb2 as above.
D) 28.b3 c2 wins.
----
Another option is 26... Rxc6 27.Bxc6 Re1+ 28.Kf2 c3 29.bxc3 Bxc3 30.Bxb5 Rc8 31.Nxc3 Rxa1 but 32.Ba4, followed by Bb3, looks advantageous for White. ----
I'm not sure but I think I'd play 26... Re1+. |
|
| Jul-21-18 | | Walter Glattke: But after 26.-Re1+ 27.Kf2 c3!? 28.bxc3 Bxc3 we have indirect guarding with no 29.Nxc3 and no 29.Nxa6 Bxa1 30.Kxe1 Rc1+
or 30.Nxc8 Rxb1, but 29.a4 bxa4 30.Ra3 |
|
| Jul-21-18 | | saturn2: I think in the line 27..c3 white is best with 28 Nxc3 RxRa1 29 NxBb4 and I dont see a clear win for black.
So 27..Re8 is better. |
|
| Jul-21-18 | | Walter Glattke: or 29.-Rc1 30.Ra3, another indirect guarding. |
|
| Jul-21-18 | | Walter Glattke: 30.-Bb2 31.Rb3 Rxb1 32.axb5 (Bxd4? Nxd4) |
|
Jul-21-18
 | | WorstPlayerEver: I missed Rxb2. Nice puzzle. |
|
| Jul-21-18 | | malt: I got 26..Re1+ 27.Kf2 c3 28.bc3
(28.K:e1 cb2+ 29.Ke2/f2 ba1=Q )
(28.N:c3 R:a1 29.N:b4 a5 )
(28.b3 c2 )
28...B:c3 29.N:c3 R:a1 |
|
| Jul-21-18 | | malt: Missed 28.N:b4, |
|
| Jul-21-18 | | Walter Glattke: malt, 28.-Bxc3 29.Nxc3? is a mistake, see my comments above. |
|
| Jul-21-18 | | Walter Glattke: Stockfish plays 27.-Re2xb2, will not play 27.-c3. |
|
| Jul-21-18 | | Walter Glattke: No stockfish plays 27.-Rce8, so the c3-attack is not good. |
|
| Jul-21-18 | | morfishine: Pathetic game by White. Who doesn't move their Queen Knight AND Queen Rook? |
|
| Jul-21-18 | | Walter Glattke: 29.a4 b4 30.a5 Rc1 31.Ra4 Rxb1 32.Nxa7 Rc5 33.Be4 Rb2+ 34.Ke3 Rxh2 a6 not easy then, Be4 looks at b1 and a8 both. |
|
| Jul-21-18 | | malt: Walter Glattke, You could be right about 29.N:c3?,
but I don't have Stockfish, nor do I want it. |
|
| Jul-21-18 | | Walter Glattke: I have no stockfish neither, analyze myself is good for chessfriends like us. |
|
| Jul-21-18 | | Strelets: It's as true today as it was of chess as played by Morphy: underdevelopment kills. Put your minor pieces and rooks on squares where they can improve your position or someone like Tan will come along and happily drop both of hers right in the middle of it. |
|
| Jul-21-18 | | malt: Walter Glattke, In two of your posts, you quote, Stockfish. |
|
| Jul-21-18 | | landshark: Spent a ton of time trying to make 26....Re1+ followed by 27....c3 work but just couldn't. Finally looking around for other stuff I settled on the move 26....Re2. Feel it holds some threats and some tension - I don't see a quick clear-cut win here. So I resorted to a positional move - |
|
| Jul-21-18 | | DarthStapler: For some reason I read it as white to move. |
|
| Jul-22-18 | | Patzer Natmas: Great game by Tan! She followed basic chess principles to pull off a winning tactic! I saw to double the rooks but I couldn't see further. |
