| May-16-11 | | sevenseaman: < al wazir: al wazir: 32...Qh6 33. Qxh6 (33. Qxf7?? Qxh2#) gxh6 34. Rg8#.> Brilliant! I could have ignored the Black Q on h6 and learnt a lesson of my life. |
|
| May-16-11 | | kevin86: A funny game: much of the early movement is by pawns and knights... The coup de grace is:32...♖e7 33 ♕f6!! gxf6 (otherwise the queen mates) 34 ♖g8# |
|
| May-16-11 | | kevin86: My bad-black's best play is after 32{...Rc2!! (threatening mate),black can draw or even win...,instead,he resigns. |
|
| May-16-11 | | Yerbamate: what about black response: Be8. I don't have any program to test the continuations...but seems good defend?
Maybe not, i'm just a noob. |
|
| May-16-11 | | sneaky pete: If 32... Re7 33.Qf6? Qxg3+ black has at least equal chances, but 33.Bxd7 .. should win. If 32... Be8 33.Qe6 Rf8 34.Qe7 .. looks good enough. |
|
| May-16-11 | | mooseheadchris: <kevin86> I think white's best response to 32... Rc2 is simply 33. Rf1 then 33... Qd2 34. Rg2 QxR 35. QxQ RxQ 36. KxR BxB 37. RxB RxR 38. exf5 Kxf7 gives white two passed pawns and probably 1-0. Should black choose not to trade down, white's game is winning. |

then 33... Qd2 34. Rg2 QxR 35. QxQ RxQ 36. KxR BxB 37. RxB RxR 38. exf5 Kxf7 gives white two passed pawns and probably 1-0. Should black choose not to trade down, white's game is winning.> Instead of 36...♗x♗, black can just play 36...♗xa4, with a winning advantage. See my post above for a better line for white that should draw, but that's the best he can hope for here. |

 | | eternaloptimist: This is perhaps the most ruthless pun that I've seen 4 game of the day. It's definitely much more ruthless than my pun which was used 4 yesterday's game of the day. Krabbe has 1 of the most interesting websites that I have ever seen.: http://www.xs4all.nl/~timkr/chess/c... |
|
| May-16-11 | | ajile: This is called "interference" correct? |
|
| May-16-11 | | Oceanlake: 17 g5? |

| | eternaloptimist: <ajile> Yes it is. I had completely forgotten about this tactic. Here is a link.: http://en.wikipedia.org/wiki/Interf...(chess)
32.♗f5!! is an excellent & difficult move to find. IM Langeweg did a great job of being alert in this game. |
|
| May-16-11 | | WhiteRook48: 32 Bf5!! is an extremely awesome move, that interferes with all of Black's defenses |
|
| May-16-11 | | sevenseaman: <ajile> <This is called "interference" correct?> Interference yes, but the technical term is 'Novotony' (or Nowotony). White intervenes a piece that can be captured by two different enemy pieces but using either Black ends up furthering White's original objective. This is what happens here;
click for larger vieww mates in 4. White inserts the R at e7 and Black cannot take it with his R ( allows 2. QxR#) or with his B (allows 2. Qxh7#). Black can refuse, say 1...Rf7 2. Rxe8+ leading to quick mate again. I had posted this position from an unknown game yesterday to illustrate 'Novotony' but no one noticed it. |
|
| May-16-11 | | ajile: Cool example. |
|
| May-17-11 | | Gilmoy: <sevenseaman>'s puzzle is an example of <Novotný interference>, after the Czech lawyer Antonín Novotný http://en.wikipedia.org/wiki/Anton%.... Novotný means you sac a piece outright on a square where two enemy line-movers criss-cross. Whichever one captures, cuts the other one's line. <ajile> is also correct: this game's finale <32.Bf5> is a "normal" interference, without anybody's name. It's not a piece sac, because White's B is simply protected. (So it's a pawn sac, but that's a lot easier to calculate.) This theme must have been known since antiquity, and we didn't need any modern composer to teach it to us. Much rarer is the <Plachutta> http://en.wikipedia.org/wiki/Plachu..., in which both line-movers move the same way. Plachutta requires 1 sac to force either defender to capture on a critical intersection, where it becomes overworked, and a 2nd sac to deflect it. That means a position where the defender has RR, QR, or QB, and the attacker has two sacs <and> a mate fork: Tarrasch vs Allies, 1914. Some newer exemplars are rumored to exist; anybody have a collection? |
|
| May-18-11 | | sevenseaman: <Gilmoy> Thanks for caring enough to explain. |
|
| Mar-07-14 | | RedShield: <Langeweg, Timothy> |
|
| Apr-12-18 | | Saniyat24: This game should be in my All Kinds Of English game collection, but that collection already has 101 games...sigh...! |
|
| Apr-12-18 | | whiteshark: <Saniyat24: This game should be in my All Kinds Of English game collection, but that collection already has 101 games...sigh...!> Why don't you make a new (second) one? Is eight the maximum you are allowed to create? |
|
| Apr-18-18 | | Saniyat24: yes, <whiteshark> 8 is my limit... |
|
| Apr-18-18 | | Saniyat24: whiteshark 8 would be a good name for a chess engine, kind of sounds like stockfish 8... |
|
| Mar-07-19 | | jith1207: How is this a win for White?
Just moving black rook along the second rank threatening mate in two saves Black's rook and bishop and White's mate threat. Resident stock fish agrees, for example 32..Rc2 gives black slight advantage of -0.62 So how was the resignation correct here? |
|
| Mar-08-20 | | jith1207: Sounds like Black missed the swindle, or perfect situation to strike back when his opponent thought he was down. <Tim Languished and kicked himself> later, for not <Krabbe-ing> the opportunity to pull Langeweg's leg. |
|
| Mar-24-21 | | rwbean: 32... ♖c2 33. ♖f1 ♕d2 34. ♕h5 ♗e8 35. ♔h1 ♖f8 36. ♕h3 ♖c1 37. ♖xc1 ♕xc1+ 38. ♖g1 ♕f4 39. ♗d7 ♗xd7 40. ♕xd7 ♕f3+ 41. ♖g2 ♕f7 42. ♕xf7 ♖xf7 is about 0.5 pawns down for White (Stockfish 13) or similarly 39... ♕f7 ... Black just saw ♗f5 and was dazzled into resigning - big mistake! |
|
| Mar-24-21 | | rwbean: Also, simpler win with 19. ♖xh7+ ♔g8 20. ♗h6 and 31... ♖a2 is a crushing win |
