 | | Clement Fraud: <After 13...bxc4 14.Bxc4 with control a2-f7> I see what you mean: After 14... Na5 15 Ba2 d3 16 Qxd3 (or Rxd3) e4!? maybe? |

Jul-10-18
 | | FSR: 34...Rxf3+! wins queen (35.gxf3 Qxc6) or king (35.Qxf3 Qa4#). |
|
| Jul-10-18 | | Patriot: 34...Rxf3+ removes the guard on a4 and the queen. 35.Qxf3 Qa4#. |
|
| Jul-10-18 | | ChessHigherCat: 34...Rxf3+ 35. Qxf3 Qa6#
I thought, What is this a Tuesday puzzle, and then I realized it's Tuesday. |

 | | Penguincw: Hoping this game isn't too famous.
Oh good, it isn't.
Black wants to mate on a4, but the queen is in the way. Don't eliminate the queen - eliminate the piece protecting the queen. If 35.Qxf3 then 35...Qa4# 0-1 and if white doesn't play 35.Qxf3, free queen. Yet another exchange sac on the f-file.
2/2 this week, and 1/2 on Tuesdays this month. |

| Jul-10-18 | | stst: Looks like Mondy:
34............RxB+
35.
PxR ===> QxQ
Rd3 block =====> RxR+ ===> Q block ===> Qa4# or P adv ===> QxQ
QxR ===> Qa4#
Hopeless for White |
|
| Jul-10-18 | | agb2002: White threatens Qxb5.
The white queen, protected by the bishop, stops Qa4#. Hence, 34... Rxf3+: A) 35.Qxf3 Qa4#.
B) 35.gxf3 Qxc6 wins. |
|
| Jul-10-18 | | saturn2: 34..RxB QxQ is mate and gxR loses the queen. |
|
| Jul-10-18 | | malt: 34...R:f3+ 35.Q:f3
(35.gf3 Q:c6 )
(35.Qc3 Qa4# )35...Qa4# |
|
| Jul-10-18 | | takchess: No effective defence to Rf3+. Either a mating net or take the queen. Happy Tuesday. |
|
| Jul-10-18 | | Walter Glattke: 34.-Rxf3+ 35.gxf3 Qxc6 or 34.-Rxf3+ 35.Qxf3 Qa4# happy Tuesday also from me. |
|
| Jul-10-18 | | Cheapo by the Dozen: Nice simple Tuesday:
1. No obvious mates.
2. White's queen is loose.
3. Therefore ... Rxf3+ is forcing.
4. Rxf3+ actually gives an immediate win. |
|
| Jul-10-18 | | leRevenant: It's lovely to see that a Top player can make a blunder like this - An' hand his opponent an easy win. |
|
| Jul-10-18 | | The Kings Domain: Good puzzle and a good and messy game. |
|
| Jul-10-18 | | Whitehat1963: Took me far too long! |
|
| Jul-10-18 | | ChessHigherCat: It's funny I'm the only one who chose Qa6# instead of Qa4#, but it's just as lethal (which is a fault for people who consider there should never be two solutions, but what the hell...) |
|
| Jul-10-18 | | patzer2: For today's Tuesday puzzle, 34...Rxf3+! +- removes the defender and decisively exposes the overloaded White Queen. The overworked White Queen cannot recapture the Rook on f3 due to the dual threats 35. gxf3 Qxc6 +- (forces mate-in-six) and 35. Qxf3 Qa4#. According to the computer, White's decisive mistake was 33. Qc3?, allowing 33...Qb5! -+ (-17.03 @ 31 ply, Stockfish 8). Necessary instead was the difficult defense 33. Qc4 Qe3+ 34. Ka2 Qc1 35. Qg4+ Bg6 36. Qd4 ⩱ to ∓ (-0.67 @ 38 ply, Stockfish 8). White's game took a big turn for the worse with 31. h4?, allowing 31...Bc2 ∓ (-0.91 @ 35 ply, Stockfish 8). Instead, 31. Rf5 Rf1 32. Rd1 = (0.00 @ 37 ply, Stockfish 8) would have given White enough counterplay to hold the draw. |

| Jul-10-18 | | Imran Iskandar: I remember seeing this game so I sort of recognized the position and recalled what the sac was. |
|
| Jul-10-18 | | Marmot PFL: 34...Rxf3+ wins, and seems to be the only way to win which is not always so. |
|
| Jul-10-18 | | King.Arthur.Brazil: It is easy to see: 34. Rxf3+ white loses the Q or is mate in the following moves. I would like say a word about some comment "Anand blundered". After 30... Rxf2, white position is not good, looks like 31.Qc3 could be more promissing than 31. h4. Maybe the expected way: 31. Qc3 Qb5 32. Rd5 Qb6... only passively waits the disaster. But, it is said that grand-masters usually make tatical and exchange moves quickly to induce opponent errors. I believe that Topalov became with doubt about the sequence above and that of 31. h4 Bc2, 32. Rd8+ Kg8 33. Qc4?! and he played quickly and cross the two lines, making an involuntary mistake. If 33. Qd5? Qe3+, while 33. Rd5? Qe8! For the move 33. Qc4 Qe3+
A)34. Qc3 (not 34...Qc1? 35. Rd1!, neither 34...Qb6 35. Rd5 Qa6+ 36. Ra5 Qf1 37. Rg5+...) 34... Rf1!
B) 34. b3 (seems the best) Qc1+ 35. Ka4 QA1+ 36. Kb5 Bf5 or 34... a6 directly. Position plenty of resourses for both.
Anytime Qg4+ must be blocked by Bg6 to avoid perpectual check with Qg4+... Qh5+...Qg4+.
(PS: hope there is no Belgian here... lgs). |

| Jul-10-18 | | morfishine: <34...Rxf3> classic remove the defender ***** |
|
| Jul-10-18 | | onedog: What I love about this position is that it seems to contradict every "rule" you are told when you are beginning to learn about chess strategy. W completely dominates the long diagonal with the monster B-Q combination. The WR controls the open file in the centre. B's K seems somewhat exposed with a broken pawn defence. Assuming the ability to foresee this position accurately say six or eight moves previously, why wouldn't W assume they were winning, and happily go into this line? I know I probably would have. Quite an easy puzzle though, once you know it's a puzzle. As they so often are. Unfortunately, OTB, nobody is there to tell you it's a "W to play and win" situation. |
|
| Jul-10-18 | | CHESSTTCAMPS: Material is even, but the white king has a weaker pawn shelter. The WQ prevents Qa4#, so black removes the guard: 34... Rxf3+ and now:
A.35.Qxf3 (or Qc3) Qa4#
B.35.gxf3 (or b3 or Ka2) Qxc6 1-0 |
|
| Jul-10-18 | | zb2cr: 34. ... Rxf3+ does it. If White retakes with the Queen, Black plays 35. ... Qa4#. If any other move such as 35. Ka2, 35. b3, or 35. gxf3, White's Queen is hanging and Black will wind up with a comfortably winning material advantage. |
