| Jan-12-11 | | David2009: Matulovic vs A Tsvetkov, 1965 postscript: Hindsight, that wonderful weapon, allied to Crafty End Game Trainer, that wonderful
free Internet resource, indicates that 31...b5 was premature. After 32 Qc1 the ever-alert EGT gives up a Pawn
with 32...Nd7 33 Qc7 Qf8 34 Qxa7 Qe8 to leave White a Pawn up. Link: http://www.chessvideos.tv/endgame-t...
Can you beat the EGT from here? As usual you are White in a position with White to play: drag and drop the move you want to make. At move 21 (Black to play)
click for larger view White has sacrificed a Pawn for faint attacking chances. Tsvetkov gave back a Pawn with 21...0-0. Crafty EGT prefers to
hold on to its extra material with 21 Kd7. Can you salvage a draw or better against the robot? Link: http://www.chessvideos.tv/endgame-t... |

| Jan-12-11 | | beenthere240: The tricky thing about the pawn endgame after the 33...f6 is that black is left in many variations with a protected passed pawn on d5, and if white tries to clean up the queenside, the pawn will run home. I think that BOSTER is certainly right in that 33...f6 is a much better move than 33...Qxe5, which loses immediately. |

| Jan-12-11 | | wals: <chrisowen> I knew I'd been missing
something. Thank heavens you're back to add some sanity to the proceedings. |
|
| Jan-12-11 | | patzer2: <wals> Thanks for the analysis showing the decisive blunder is apparently 31...b5?, allowing 32. Qc8! . I thought Black might hold after 32...Ne7. However, after 32... Ne7 33. Qc5! Qf8 34. Qxa7 , White is winning as play could continue 34...Qd8 35. h5 gxh5 36. gxh5 Kg7 37. h6+ Kg6 38. f4 Qe8 39. h7 Kg7 40. a3 Nc6 41. Qc5 Ne7 42. Kf3 Nf5 43. Kg2 Nh4+ 44. Kh3 Nf5 45.

Kxh7 38.Kxd4: 
click for larger viewWhite shouldn't have any trouble winning - rather than clean up the queenside, he wins by bringing the king to e5 - it's either queening the f-pawn after Kxe6, or 38...Kg8 39.Ke5 Kf7 40.h5! if Black tries to defend it. The d-pawn will always be too late. (Besides, as <Sastre> notes in his line, White has an alternative way - forcing the win of a piece - with 34.exf6.) |
|
| Jan-12-11 | | BOSTER: <Sastre> Of course! You are right!
Such manoeuvre when you moving the queen all the time with tempo(check) and keeping an eye (contact) on the knight d4 is very useful.
I did not see it here. |
|
| Jan-12-11 | | ounos: Bah. All this craziness took place just because 21. ...Kd7 looked too ugly for black to play. |
|
| Jan-13-11 | | Lennonfan: Wow! 32.Qc1! is total wizardry..i would never have seen that combination if id looked for a wk.as im sure a lot of you others wouldn't also...im just wandering that the people on this site that use computer analysis(its just i dont) if they'd run that position thru rybka or fritz and see if a strong engine could see the combination...and for the knight to take the pawn with check on move 33 is too tempting...brilliant stuff |
|
| Jan-13-11 | | TheRavenPK: <starkidaway>, <beenthere240> :D Yes, you are right! Perhaps I don't recall the position correctly, or at least I hope so.. You know, I am still an amateur, rated 1000, I can make mistakes :) |

 | | GrahamClayton: Nice double-back by Matulovic with 32. Qc1, exploiting the unprotected knight on c6. |

| Mar-15-25 | | King.Arthur.Brazil: The king thought about this line: 32. h5 a5 33. h6 Qf8 34. h7+ Kh8 35. Nxe6 Qe7 36. Ng5 Nd8 37. Qf6+ Qxf6 38. exf6 b4 39. Kd2 a4 40. Kc2 and win. |

 | | scormus: I didn't get this at all, and completely missed the remarkable tactical shot (35 Qxh8+!). I thought W was going to win by positional manouvering. I'd say B could be forgiven for not realising that 32 ... Nxd5+ would lose the N. |
|
| Mar-15-25 | | Messiah: It was surprisingly easy for me. Good puzzle, anyway! |

|
| Mar-15-25 | | JohnBoy: I am w <scormus>. Qc1 was dismissed as losing two pawns. The puzzle requires six moves by white, spotting that giving up a pawn for the trade of queens leaves the black knight stranded. Well beyond me. |

 | | al wazir: 32. Qc1 Nxd4+ 33. Kd3 Qxe5 34. Qc8+ Kg7 was obvious. What else is there? But I didn't come close to finding 35. Qh8+ Kxh8 36. Nxf7+ Kg7, much less seeing that after 37. Nxe5 the black knight is trapped. |
|
| Mar-15-25 | | alshatranji: I saw as far as 32.Qc1Nxd4+33.Kd3Qxe5, but the idea of trapping the knight with Qc3 is countered with the simple f6. I couldn't see anything after Qc8+Kg7. Well. |
|
| Mar-15-25 | | Walter Glattke: I did not plan Qh8+!! Kxh8 Nxf7+ with fork and knight catch, but Matulovic is GM. Gratulation.
White attacks on queen's wing with 32.Nf3 Qf8 33..Qc1 won ending. |

| Mar-15-25 | | Granny O Doul: Very elegant combination of themes. |
