| Aug-04-07 | | patzer2: For today's difficult Saturday puzzle solution, White springs a deep passed pawn combination which begins with the cleverly combined deflection and decoy pseudo-sacrifice 33...h3+!! If White takes the 33...h3!! bait he gets mated or loses his Queen to a discovered check. If he declines it, White follows up as in the game with five consecutive decoys to simplify and allow the Black h-pawn to pass and promote to Queen. |

 | | fm avari viraf: At first sight, it looks that Black's Queen is trapped since 33...Qxd4? would lose to 34.Rc7+ Kxc7 & 35.Qxd4. Hence, 33...h3+! 34.Kf3 [ not 34.Kxh3 Qf1+ 35.Qg2 Qf5+ wins or 35.Kh4 then Bg5+ wins ] 34...Qf1+ 35.Qf2 Qd1+ 36.Qe2 forced & the rest is all tactics. |

| Aug-04-07 | | bakuazer: it took me long time to get this. I was thinking about hxg3. I think this leads to unclear Q aginst R+B ending and there are some interesting lines here. Only some 8-10 minutes later I noticed h3 move. At first I thought it does not lead anywhere after Kf3. (the other cases are easy) but then amazing Qd1+ wins immediately. I had a psychological problem because i was thinking that saturday puzzle must be a long and subtle endgame but this one wins instantly. 6/6 this week, looking forward to solving sunday puzzle :). |
|
| Aug-04-07 | | beginner64: <Waitaka: See h3+ is easy, even I saw it. But you can only take credit if you see the pawn promotion to Q, after the R sacrifice.> My post in the beginning (3rd one) shows how black can win without the R sac as well. |
|
| Aug-04-07 | | uuft: Easy. 6/6 |
|
| Aug-04-07 | | uuft: Easy for a saturday, I mean. h3+ stood out to me in under one second (fastest Saturday ever). 15 minutes later I put all my money on it. And yes, I am thinking about quitting the dayjob. But don't tell her ;) |

| Aug-04-07 | | tomek322: I missed it I was thinking
33.... Qxc3
34. Qxc3 Rxg3+
35. Qxg3 Pxg3
Obviously doesn't win the game as quickly, but we are now ahead a bishop and should still win. Any comments? |

why 35.Qxg3? You are missing 35.h2xg3. |

| Aug-06-07 | | Crowaholic: Nice. Got the entire combination down to the very end where I saw that 35. ..Qd1+ followed by the rook sac and queen exchange leaves White with no way to stop the h pawn. Well, first, I considered numerous other moves such as Qxc3, hxg3, Rxg3 but nothing came of them. I immediately saw the clearance sac Rc7+ with which White would punish Qxd4. Then I noticed that White probably intended the bishop to be taken, so what about spoiling this plan with h3+?!. Then, it's easy to see that Kxh3 leads to mate with Qf1+, Kf3 leads to Qf1+ with the unstoppable promotion as played, Kh1 leads to mate in 1, but it was more difficult for me to analyze 34. Kf2. ..Qxd4+ is obvious - now White doesn't have the tempo to play Rc7+ - and so is 35. Kf1 Qc1+ 36. Kf2 but now what? The answer as dzechiel found (respect!) is that 36. ..Bd2! leaves White in total despair. Unfortunately, I missed this part and wanted to play Qh1?? instead, which according to computer analysis still leaves Black with an advantage, but only a moderate one, since 37. Qc2! gives White a powerful mate threat. Now the queen exchange with ..Qg2+ 38. Ke1 Qxc2 39. Rxc2 is forced, then ..Rg4 and the Spike engine gives this an eval of about -2.7 at 20 ply. |

| Sep-29-18 | | Daodejing: By the way, that was the important game of the world junior championships 1986 Gausdal to decide the winner. A great talent of Austria is Josef Klinger (see photo), born in 1967 in St.Johann im Pongau. Accompanied by ÖSB early, he played trained by IM Georg Danner, three youth World Championships. In 1983 he is in Belfort 7.-11. from 61 and beats u.a. Nigel Short. In 1985, he is bronze in third place of 69 in the Emirates. In 1986 he plays in Gausdal in the last round against the Cubans Arencibia for first place. It's like Lasker vs Schlechter in 1910. Klinger would be world champion with a draw, but Arencibia wins the game and Klinger is fifth, ahead of Anand. Klinger becomes international champion in 1985 and has the second best result behind Kasparov at the 1986 Chess Olympiad in Dubai on board one. In 1988, he becomes grandmaster and skips in the Elo list of FIDE as the first Austrian, the 2500-point wall. From 1990 he retires from competitive chess. |

| Dec-13-19 | | Walter Glattke: Black queen catching, 33.-Qd4? 34.Rc7+, therefore 34.-h3 to free the queen. 34.Kg1 /Kf2 Qxd4+ wins at least a pawn, therefore 34.Kf3 Qf1+ 35.Bf2!? Rg3+ 36.hxg3 h2 wins for black or 35.Qf2 Qd1+ as in the match, so Bh6 denies Rc1, and the pawn runs through. |

| Dec-13-19 | | saturn2: 'Rod save the Queen'
I was seeing 33...h3 (Qxd4 34 Rc7) the queen is almost trapped. 34 Kxh3 Qf1+
34. Kg1 Qxd4+ (with check it works)
34.Kf3 Qf1+ 35. Qf2 Qd1+ 36. Qe2 Rxg3+ 37. hxg3 -
Qxe2+ (here I was thinking Qg1 also works but 38 Qxb5 is check) 38. Kxe2 h2 |
|
| Dec-13-19 | | Lambda: Very easy to see h3+ is the best move here, it's the only way of saving the queen. What to play in a couple of moves time can be calculated when you get there. |
|
| Dec-13-19 | | EIDorado: h3 is kind of forced. Then you have to compute the resulting variations. |

 | | agb2002: The black queen is trapped (33... Qxd4 34.Rc7+). However, Black has 33... h3+:
A) 34.Kxh3 Qf1+
A.1) 35.Qg2 Qf5+ 36.Kh4 Qg4#.
A.2) 35.Kh4 Bg5+ 36.Kg4 (36.Kh5 Qh3+ 37.Bh4 Qxh4#) 36... Qf5+ 37.Kh5 Rh8#. B) 34.Kh1 Qf1#.
C) 34.Kg1 Qxd4+
C.1) 35.Qf2 Qxc3 36.Qxa7+ Qc7 wins.
C.2) 35.Kh1 Qd1+ 36.Be1 Qxe1#.
C.3) 35.Kf1 Qd1+ 36.Kf2 d4, with an extra pawn and the double threat dxc3 and Be3+, looks winning. D) 34.Kf2 Qxd4+
D.1) 35.Kf1 Qd1+ transposes to C.3.
D.2) 35.Ke1 Qg1+ 36.Ke2 Rxg3 (36... Qe2+ 37.Bf2 Qxf2+ 38.Kxf2 Rg2+ wins a piece but looks slower) D.2.a) 37.Rxg3 Qxh2+ wins decisive material.
D.2.b) 37.hxg3 Qg2+ as above.
D.2.c) 37.Rc7+ Kxc7 38.Qc2+ Kd7 39.hxg3 (39.Qc5 Qxc5) 39... Qg2+ 40.Kd3 (40.Kd1 Qf1#) 40... Qf3+ 41.Kd4 Qe3#. E) 34.Kf3 Qf1+
E.1) 35.Bf2 Qg2+ 36.Ke2 Qxf2+ 37.Kxf2 Rg2+ wins a piece. E.2) 35.Qf2 Qd1+ 36.Qe2 Rxg3+ 37.hxg3 (37.Kxg3 Qxe2 wins) 37... Qxe2+ 38.Kxe2 h2 followed by h1=Q winning (39.Rc1 Bxc1). |

 | | ClassZPlaya: 32. Rc3 looks so good on the surface - it almost wins a Queen by force. Looking deeper it loses by force! 32. Bxh4 Rg8+ 33. Bg3 Rg4 34. Rc3 Qxd4 35. Qc2 Qd2+ 36. Qxd2 Bxd2 leaves Black with a small edge but I think White should be able to hold this. |
|
| Dec-13-19 | | Eduardo Leon: The first move is obvious.
<33...h3+ 34.♔f3> Either 34.♔g1 or 34.♔f2 would be met with 34...♕xd4+, and this check prevents white's own 35.♖c7+. And, of course, 34.♔h1 ♕f1#. <34...♕f1+>
Of course, not 33...♕xd4 34.♖c7+, and white turns the tables. <35.♕f2>
Forced, since 35.♗f2 loses even more quickly: 35...♕d1+ 36.♕e2 ♕h1#. <35...♕d1+ 36.♕e2 ♖xg3+ 37.hxg3 ♕xe2+ 38.♔xe2 h2> White cannot play 39.♖c1, so the h pawn cannot be stopped. |
|
| Dec-13-19 | | King.Arthur.Brazil: This time the answer 33...h3+! is very simple, objective and it is not so hard to find. Other answers different from 34.♔f3 lead to loose the ♕ or to check-mate move (the majority). |
|
| Dec-13-19 | | RKnight: Darn. I was proud of getting this one, and not just 33...h3+ but the follow-up. Then I read the comments on how obvious and simple it was :-( C'est la vie. |
|
| Dec-13-19 | | 5hrsolver: 33...h3+ 34. Kf3 Qf1+
Here if 35. Bf2 then Qd1+ 36. Qe2 Qh1# Is quick mate. |
|
| Dec-13-19 | | eblunt: He just sm*a*s*hes Rodriguez |
|
| Dec-13-19 | | belgradegambit: I was also proud to solve this but then realized I had solved it back in 2007 as well. Let's see if I can solve it in 2031. |
|
| Dec-13-19 | | patzer2: I remembered this neat combination from 12 years ago. Once you break it down, keeping in mind the objective of creating a passed pawn, today's Friday (33...?) puzzle is not too difficult. P.S.: According to the computer, White's decisive error was 32. Rc3? allowing 32...Rg8+! -+ (-11.85 @ 33 ply, Stockfish 10). Instead, White can get practical drawing chances with the tortuous defense 32. Kh3 Rg8 33. Qf2 Bf4 ∓ (-1.03 @ 50 ply, Stockfish 10). But against strong play, Black is probably lost after 32. Kh3 Rg8 ∓ (-1.03 @ 50 ply) or 32. Kh3 a6 ∓ (-1.18 @ 50 ply). One move earlier, instead of 31. Be1? allowing 31...Kd7! ∓ (-0.94 @ 37 ply, Stockish 10), Black can fully equalize with 31. Kh3 = (0.00 @ 41 ply). |

 | | drollere: the mating combinations that follow from 34. K:h3 are a fun feature of the combination. |
