| Oct-22-07 | | moppa: Nice game. 6...Rb8 seems to score pretty well for black, according the Opening Explorer |
|
| Apr-14-17 | | yadasampati: White is finished. After 40. Qb1 (the only move) follows Qxb1+ Kxb1 Nd2+ and the rook is also lost, leaving white with a lonely knight against two pawns, a knight, a bishop and a rook. |
|
| Apr-14-17 | | Walter Glattke: 36.Qe3 Qc4+ allows 3 white answers
with black Advantage. |
|
| Apr-14-17 | | AlicesKnight: 34....Rxe2+ seems the best way in; after 35.Kxe2 the pin allows ...Qxe4+ and there should be a way in with the cover blown (no time today). |
|
| Apr-14-17 | | groog: Pretty straightforward for a Friday. |
|
| Apr-14-17 | | Moszkowski012273: 29...Qg5 is much better. 31.0-0-0 is MUCH better. And lastly,,, 33...Bxe4 is damn near mating! |

 | | Dionysius1: A lot of tactical threats along the way from 34...Rxe2 (mates with bishop or Knight forks). But at

why didn't White play 37 Ke1 or Ke2?
At least she'd last longer wouldn't she? Or at least protect the N on f2. |

| Apr-14-17 | | stacase: <groog: Pretty straightforward for a Friday.>
Agree |
|
| Apr-14-17 | | Moszkowski012273: Actually 40...QxQ isn't correct <yadasampati>. |
|
| Apr-14-17 | | morfishine: After <34.Rxe2+> followed by <35.Qe4+> (taking advantage of the pinned Knight) Black has a permanent attacking momentum winning ***** |
|
| Apr-14-17 | | Moszkowski012273: 37.Ke1,Nf3+ wins the Queen.
37.Ke2,Nc4 38.Qa2,Bf3+! |

<36 Kd1 Qd4+>
click for larger viewAt this point we reach the main decision for black; a) lose very quickly with Ke1/Ke2/Kc2
37 Ke1 Nf3+
38 Qxf3 Bxf3 (Ke2 Qd2#)
37 Ke2 Bf3+
38 Ke1 Nc4!
39 Qd3 Qxa1+ mating (Qb2 Qc3+ mating)
37 Kc2 Be4+
38 Kc1 Qc4+ (Kb3 Qc4+ Kb2 Qc2#)
b) lose pretty quickly with Kc1
37 Kc1 Nc4!

I found the last option a little bit interesting... |
|
| Apr-14-17 | | agb2002: Black has an extra pawn.
White threatens Qxb2 and Qxd6+.
The first idea that comes to mind is 34... Rxf2 35.Qxb2 Rxe2+ 36.Kxe2 Qh2+ 37.Rf2 Qxf2+ 38.Kxf2 Nd3+ 39.Kf3 Nxb2 40.Rb1 Bxe4+ 41.Kxe4 Na4 unclear. Another option is 34... Rxe2+ 35.Kxe2 Qxe4+:
A) 36.Qe3 Qc2+ 37.Qd2 (37.Ke1 Nf3+ 38.Qxf3 Bxf3 wins) 37... Qc4+ A.1) 38.Ke3 Rh3+ 39.Nxh3 Ng4#.
A.2) 38.Ke1 Nf3+ wins.
A.3) 38.Kd1 Qxf1+ wins decisive material.
B) 36.Kd1 Qd4+
B.1) 36.Kc1 Rxf2 37.Rxf2 Nd3+ and 38... Nxf2 - + [b+n+2p vs R]. B.2) 36.Kc2 Rxf2+ 37.Rxf2 Qxf2+ as above.
B.3) 36.Ke1 Nf3+ 37.Qxf3 (37.Ke2 Qd2#) 37... Bxf3 wins. B.4) 36.Ke2 Bf3+ 37.Ke1 Rxf2 38.Rxf2 Nd3+ wins decisive material. C) 36.Kd2 Rxf2+ 37.Rxf2 (else mate in two) 37... Nc4+ followed by 38... Nxa3 - + [q+b+2p vs 2R]. |

 | | Richard Taylor: I didn't solve it as such but saw the main moves. It is complex and I saw some epaulette mates on c2. But then I thought Black had a way to pick up White's Queen. It was a nice game by Black keeping the attacking initiative against the annoying Closed Sicilian. |

| Apr-14-17 | | patzer2: Took me a while, but I finally saw the promising possibility <34...Rxe2+! 35. Kxe2 36. Qxe4+  > cracking open the un-castled King position for a promising attack to solve today's Friday puzzle.Here's some analysis toward the end of the game with Deep Fritz 15: <31. Rf1?> This is White's decisive mistake. Instead, 31. O-O-O Bc6 (not 31... Qxf2?? 32. Qxd6+ Ke8 33. Rg8#) 32. Rgf1  holds the position a pawn up for White. <31... Rxc2> With this obvious pawn grab, Black is now winning. Fritz gives Black a near four pawn advantage after 31...Rxc2 32. Kd1 Nc4 (-3.74 @ 20 depth, Deep Fritz 15) <32. Qb3 Rxb2 33. Qg3 Qh4 34. Qa3 Rxe2+!> This standard echange sacrifice to expose the King to a decisive attack is the start of today's Friday puzzle. <35. Kxe2 Qxe4+ 36. Kd1> This is pretty much forced. If 36. Qe3, then Black wins after 36...Qc2+ 37. Qd2 Qc4+ (not 37... Bf3+? 38. Ke1 Nd3+ 39. Qxd3 Qxd3 40. Nxd3 Re2+ 41. Kd1 Rf2+ 42. Ke1 Re2+ 43. Kd1 Rf2+ 44. Ke1 Re2+ =) 38. Ke3 Ng4+ 39. Nxg4 Qe4# <36... Qd4+ 37. Kc1 Nc4 38. Qa2 Qc3+ 39. Qc2> If 39. Kb1, then it's mate after 39...Be4+ 40. Nxe4 Qd3+ 41. Kc1 Qxf1#. If 39. Kd1, then 39...Bf3+ 40. Qe2 Qd2# ends it. <39... Qxa1+ 0-1> White resigns in lieu of 40.Qb1 Qa3+ 41.Kc2 Be4+ 42.Kd1 Qf3+ 43.Kc1 Qe3+ 44.Kd1 Qd2# |

| Apr-14-17 | | ChessHigherCat: <Jimfromprovidence:> I hope I understand the diagram and move order correctly (for once), plus this is my pre-coffee phase, but it looks to me that if the Rook takes a piece each move it's not a stalemate: 44 Rxd6+ Kc4/e4 45. Rxd4+ Kc3/e3 46. Rxd+3 Kxd3 37. Kc1/e1 Maybe a perpetual is possible with that line, though. |

|
| Apr-14-17 | | Exploding: <<Jimfromprovidence>> Its clear that 43...Kd5?? 44 Rxd6+! draws. But is black plays 43...Kf5!! when white plays 43 Re6+, Black wins: 44 Rf6+ Ke4! and any rook check is met by a interference of the knight and discovered check. e.g. 45 Rf4+ Nxf4+ 46 Ke1 Qg1#. |

| Apr-14-17 | | swclark25: Following the game line, I don't understand 37)...Nc4. Would 38)Rd1 be a better response from White than Qa2? |

| Apr-14-17 | | ChessHigherCat: <swclark25: Following the game line, I don't understand 37)...Nc4. Would 38)Rd1 be a better response from White than Qa2?>
I don't think so, because 39) Rd1 Qxf2
<CG> Sorry about the double posts again, I tried to delete the first one but it returned to haunt me |
|
| Apr-17-17 | | swclark25: <ChessHigherCat> thanks for the reply. I didn't see Qxf2. Guess the White Rook can't protect the Knight and threaten Black Queen at the same time from Rd1. |
