 | | agb2002: Black has a knight for a bishop and a pawn.
White threatens to incorporate the king rook into play with Rg1. White's worst weakness is f3. Hence, 23... Rhf8 24.Bxf8 (this merely delays the disaster) 25... Rxf8: A) 25.f4 Qe4+ 26.Kd1 (26.Kf1 Qxh1+ - + [N vs P]; 26.Qe3 Nxe3 - + [Q vs R]) 26... Qxh1+ 27.Kc2 Qxh2 - + [N]. B) 25.Rg1 Qxf3+ 26.Ke1 (26.Kf1 Qxf2#) 26... Qxf2+ 27.Kd1 Nb2+ (or 27... Qxg1+ 28.Kc2 Rf2+ 29.Kb3 Qxh2 - +) 28.Qxb2 Qxb2 29.Rc1 Rf2 - +. C) 25.Rf1 Qxf3+ 26.Ke1 Rf4 - +, with the threat 27... Re4+. D) 25.Kd3 Qxf2 26.f4 Rxf4 - +, with the threat 27... Rf3+. E) 25.Q(R)d1 Qxf3+ 26.Ke(f)1 Qxf2#.
F) 25.Qe1 Qxf3+ 26.Kf1 Qxh1+ - + [N].
G) 25.Qf1 Qxf3+ 26.Ke1 Qxc3+ 27.Kd1(e2) Qd2#.
H) 25.Qg1 Qxf3+
H.1) 26.Ke1 Qxc3+ 27.Kf1 (27.Kd1 Qd2#; 27.Ke2 Qd2+ 28.Kf1 Ne3#) 27... Qxa1+ - + [N+P]. H.2) 26.Kf1 Ne3+ 27.Ke1 Nc2+ 28.Kd2 (28.Kf1 Nxa1 - +) 28... Qxf2+ 29.Qxf2 (29.Kc1 Qxg1 30.Rxg1 Nxa1 - +; 29.Kd3 Rf3#) 29... Rxf2+ 30.Kd3 Nxa1 31.Rxa1 Rxh2 - + [2P]. H.3) 26.Kf1 Nd2+ 27.Ke1 Qxc3 28.Ke2 (28.Kd1 Nf3 - +) 28... Ne4 looks also winning. |

 | | kevin86: The rook to the f-file was clearly the key,one rook is expendeble,the second will force a breakthrough. |
|
| Feb-23-12 | | Marmot PFL: 23...Rf8 was not too hard to play, since white can't defend f3 at all. 8...Bg4? is awful, yet white still loses. It shouldn't take a genius to just castle and win with the extra pawn. |
|
| Feb-23-12 | | David2009: D Flynn vs F Scheckenbach, 2012 Black 23...? 23...Rhf1 pressurises the f3 Pawn. Main variation: 24.Bxf8 Rxf8 GOOT! since 25.f4 allows Qg4+ 26.Kd3 Rxf4 and the attack continues.
As White, I would try to muddy the waters with 24.Bd6+!? since if 24...Ka8 25.Bxf8 Rxf8 26.f4 Qg4+ 27.Kd3 Rxf4 28.Rf1 might create nebulous back rank mating threats if Black ever captures the f2 Pawn: but Black can play the pragmatic 24...Nxd3 with a risk-free attack. The best is the enemy of the good. Time to
check:

The ES puts up its usual tough fight but it should lose - fair enough I only drew first time round. I console myself with the fact that, against a human opponent in a tournament game, I would think longer bnefore blundering. Enjoy the challenge of winning first time round without an engine! |

| Feb-23-12 | | Memethecat: <OhioChessFan My dialup at home is too slow, so here I sit at the library to watch the video. The actress is British, so maybe it was a UK product. But it rang a bell, though I can't remember for sure. Sure is a catchy little tune.> I used to play the odd gig & would occasionally belt this tune out to lighten the mood. It was amazing how many people knew the words, especially since it's not been on TV for 20yrs. ^.^ |

Electric rooks shepherd in wait allowed to sac one queen dominant it should get going for black I delve in f8 bishop in rook over f3 bubbles up as it cant be defended! In whites camp I dont see good options prevent qe4 rf4 or get he gunwhales ba3 homeward bound James horses c4 and queen carriage g2 in f8 definatley fit the bill in fed rf1 met to siren in flashing us f4 in direct approach white mind you will ok lose his queen in. Staving off the mate rhf8 bxf8 rxf8 in staving off the rook queen drop to punch in, nuts hanging king e2 ears lovely coup de grace in f4 kurfew. Main seesaw battle go back in g4 |

Wonderful reading, sir. |
|
| Feb-23-12 | | Crispy Seagull: I was able to spot move 23 fairly easily, which should say something for this Thursday puzzle. |
|
| Feb-23-12 | | jackpawn: The puzzle itself wasn't hard. I was more taken by the game itself. It was brutal. Hard to believe a near master (2182) could play a move like 8 .. Bg4, permitting a stock combination. At that point of course he's busted. But then white begins potzing around and managed to lose. Ugly . . |
|
| Feb-23-12 | | Shams: <jackpawn><But then white begins potzing around and managed to lose.> Yeah. I think I like 11.h3 intending 11...Bh5 12.e5+ as an improvement. What do you think? |

 | | LIFE Master AJ: http://www.chessvideos.tv/endgame-t... <David2009> I tried 2-3 times before I got it right, I did not use computer assistance and tried not to take more than 5-10 seconds on any one move. It was far from easy ... |
|
| Feb-23-12 | | TheBish: D Flynn vs F Scheckenbach, 2012 Black to play (23...?) "Medium"
White is up a pawn, but it's doubled. Black's queen and knight are well placed, but he needs to add a rook to the equation to have a successful attack. The best place for a rook is the f-file, but moving one there immediately loses the exchange. Do we care? Not if the ensuing attack is successful! 23...Rhf8! (or Rcf8) 24. Bxf8 Rxf8
So White is thinking, "OK, I won some material, but now how do I defend my king?" Black is threatening 25...Qxf3+ 26. Ke1 (or 26. Kf1 Qxf2#) Qxh1+ 27. Ke2 Qf3+ 28. Ke1 Qxf2+ 29. Kd1 Ne3+, winning the queen and soon mating. So let's look at tries for White: A) 25. Kd3 Qxf2! (not 25...Rxf3+ 26. Kc2 Qxf2+ Kb3) 26. Re1 Rxf3+ 27. Re3 Rxe3+ wins the queen. B) 25. Rf1 Rxf3! exploits the queen's pin of the f2 pawn, threatening ...Re3+, winning the queen. White has no good defense to this threat. C) 25. Rd1 Qxf3+ 26. Ke1 Qxf2#.
D) 25. Rg1 Qxf3+ 26. Ke1 Qxf2+ 27. Kd1 and now Black can choose between winning the rook or the queen with 27...Ne3+ 28. Qxe3 Qxe3. D) 25. Ra2 Qxf3+ 26. Ke1 Qxh1+ 27. Ke2 Qxc1 wins the house. An interesting try is similar to line D, without taking the rook on f8 first: 23...Rhf8 24. Ra2 Qxf3+ 25. Ke1 Qxh1+ 26. Ke2 Rxf2+! 27. Kxf2 Qxh2+ 28. Kf3 Qxa2, when Black remains a rook and two pawns up for an easy win. |
|
| Feb-23-12 | | TheBish: Hmmm... I missed the simplest win in the game continuation. That was the only thing I was questioning, that in my line Black wins the queen, but for a rook and knight -- after already giving up the exchange, so not an easy way to win if at all. I'm sure (or at least hope) that I would not miss that in a game situation, where I'm looking at full size (3D) pieces and not a small 2D board! |
|
| Feb-23-12 | | Madman99X: Maybe some of you deep thinker types can help me out here. Why not 9... Kxf7 ? Surely the position after 10. Ng5+ Ke8 11. Qg4 dxe5 is better than the text?
click for larger viewBlack's pawn structure is lacking and he can't castle, but he's hosed in both of those departments anyway. This at least gives him some breathing room. |
|
| Feb-23-12 | | psmith: I am going to guess the solution is 23…Rhf8 and then 24. Bxf8 Rxf8
(a) 25. Rf1 (or 25. Qf1 – either to cover f2) Qxf3+ 26. Ke1 Rf4 threatening 27… Re4. I think Black wins.
(b) 25. f4 Qe4+ and 26…Qxh1+
(c) 25. Qg1 Qxf3+ 26. Kf1 Nd2+ 27. Ke1 Qxc3 threatening both Qxa1+ and Nxf3+. Probably missing some subtleties… good enough? |
|
| Feb-23-12 | | Nemesistic: This is really easy for a Thursday, is it just me who's seen harder Monday's?? No point posting the moves as 90% of you guys already nailed it, mostly agreeing on, well everything! I'll crack a Sunday POTD soon... |
|
| Feb-24-12 | | rilkefan: <Madman99X> - you're right. Black should have played 8...d5 or ...dxe5. Your line is a lot better than ...Kd7. I figure black was so surprised by Bxf7 that he got discombobulated. |
|
| Feb-24-12 | | SChesshevsky: A very instructive game I thought.
If Black did somehow overlook 9. Bxf7, his play to fix his weaknesses and build up his strengths seems to show why he's 2000+. Maybe after 12. Nc3 white has some advantages but with Black's open lines for the Q & B and the strong pin on f6, the open c & f files, and the weak white d-pawn, I'm guessing it would take some precise play by White to really cash in. And as the game shows some poor choices by White can quickly turn out badly. |
