| May-14-07 | | whiteshark: 35... Qxb2 / ...Qf6 / ...Re5 are also winning.
Playing the "surprising, weaker" 35...g5 shows black's position is so superior, that white should resign. And he did. |

| Aug-19-16 | | zanzibar: White would be OK with 28.Qd1 instead of 28.Qg2:

4r1k1 /pp3pp1/2p3p1/5pn1/3P4/2PRNQPq/PP3P1P/6K1 w - - 0 28 It's funny, but 28.Qg2, instead of strengthening the white squares, actually eventually allows their exploitation. Here's the tactical at Black's move 30
(Black to move after 30.h3)

4r1k1 /pp3pp1/2p3p1/5p1q/3P4/2PRNnPP/PP3PQ1/5K2 b - - 0 30 If I were one to submit game puns this would be a ply on this: <Blue Mitchell - Out of the Blue> https://en.wikipedia.org/wiki/Blue_... |

| Aug-19-16 | | WorstPlayerEver: 24. Rd3 doesn't look good either. I'd play 24. d5 |
|
| Aug-19-16 | | zanzibar: <WPE> you mean 24.Re3 right? 24.d5, doesn't that just throw away the pawn? |
|
| Aug-19-16 | | WorstPlayerEver: <zanzibar>
Oops! Thanks for correcting me, zanzibar. I meant 27. Rd3 So 27. d5
I had to use my brain; my engines are occupied atm
Weird thing is: I didn't look before move 27 and still connected a rook move to the 24th move. Time for a break! ;) |
|
| Aug-19-16 | | zanzibar: <WPE> ah, that makes sense now. Yes, 27.d5 is better, and makes for an interesting comparison why it holds, whereas the game fails, for White. |
|
| Sep-15-16 | | Fish55: White's knight can't move (except to c2) due to mate on e1. Black's combination takes advantage of this. If 32.Ke2, Rxe3+ followed by Qxd3+ and Ne1+ wins a piece. |

Well, I did see as far as <30...f4 31.gxf4>

Sadly, I didn't see Alekhine's 31...Qb5! at all. The best I found was the inferior <31...Qf5>, momentarily relinquishing my defense of Nf3 in order to attack white's Rd3. I figure black saves the rook with <32.Rd1>, allowing <32...Qxf4>, and I once again defend Nf3.

What have I accomplished? Not much, but black's kingside pawns are a mess and white remains on the defensive. Passable play, but not inspired. I was pretty sure this *wasn't* the solution. |

| Sep-15-16 | | drollere: The only approach I could find assumed that moving the black N was the right approach. But I could not find a way to get the Q to the first rank. I considered f4 to dislodge the white N but thought gxf4, Nh4, Qg4 would hold. In the game, the point of f4 is just to clear a path for the Q, not dislodge the N. Qb5 was a brilliant shot, winning at least the exchange, but the real point wasn't obvious to me until c4, Qxc4! The white N cannot capture, because Re1 does the rest. One of the prettiest examples of "seeing the whole board." |
|
| Sep-15-16 | | PJs Studio: Swing and a miss. Alekhine was a madman. |
|
| Sep-15-16 | | PJs Studio: In looking at the whole game score Bluemich played this game very poorly. |

| Sep-15-16 | | patzer2: Missed the clearance and pinning combination 30...f4! 31. gxf4 Qb5!  (-3.11 @ 28 depth,Komodo 9.3) solving today's Thursday puzzle.My less strong attempt was 30... g5 31. g4 fxg4 32. hxg4 Qg6 33. Rd1 Nh4  (-0.72 @ 21 depth, Deep Fritz 15). White's game takes a turn for the worse with 28. Qg2? Qh5 (-1.06 @ 20 depth, Deep Fritz 15). Instead, 28. Qd1 f4 29. Ng2 = (0.00 @ 20 depth, Deep Fritz 15) holds it level. |
|
| Sep-15-16 | | WorstPlayerEver: If 32. Ke2 then Qd3 |
|
| Sep-15-16 | | agb2002: The material is identical.
White threatens g4.
The white knight stops ... Re1#. The pawn on f5 blocks the queen (... Qb5). These details lead to consider 30... f5: A) 31.gxf4 Qb5
A.1) 32.c4 Qxc4 33.Ke2 (33.Nxc4 Re1#) 33... Qc2+ (or 33... Ne1) 34.Kxf3 Qxd3 - + [R vs N]. A.2) 32.Ke2 Ne1 33.Kxe1 (33.c4 Qxc4 as in A.1) 33... Qxd3 - + [R vs N+P] followed by Qb1 and White's queenside is about to disappear. A.3) 32.Qxf3 Qxd3+ 33.Kg2 (else 33... Qb1+) 33... Qb1 as in A.2. B) 31.g4 Qb5 (31... fxe3 32.Qxf3 -32.gxh5 e2#- is unnecessarily complex) as in A. C) 31.Nc2 Nh4
C.1) 32.gxh4 Qe2+ 33.Kg1 Qxd3 - + [R vs N].
C.2) 32.g4 Qb5 and the double threat 33... Nxg2 and 33... Qxd3+ wins. C.3) 32.Qg1 Qe2#.
C.4) 32.Qh1(2) Qe2+ wins.
D) 31.Ke2 Nxd4+ wins. |

| Sep-15-16 | | gofer: I don't know why but this took ages. The pawn push was obvious, because Ne3 is stuck due to Re1#. <30 ... f4>
<31 gxf4 ...>
But after that I was looking at all sorts of things rather than exploiting the pin. I eventually saw the pin and everything was obvious from then on... <31 ... Qb5!>
32 Ke2 Qxd3
33 Kxd3 Ne1+
<32 Qxf3 Qxd3+> <33 Kg2 Qb1>
click for larger viewBlack regains at least one pawn and remains an exchange up, given white's
weak kingside pawn structure black is probably winning at a canter... ~~~
I was surprised white played <32 c4?!> This seems to loose two central pawns... |

| Sep-15-16 | | patzer2: <WorstPlayerEver: If 32. Ke2 then Qd3> Apparently you saw the Knight Fork combination 32. Ke2 Qxd3 33. Kxd3 Ne1+
34. Kd2 Nxg2 (-2.14 @ 21 depth, Deep Fritz 15). Also winning is <agb2002>'s line 32. Ke2 Ne1 33. Kxe1 Qxd3 (-3.64 @ 21 depth, Deep Fritz 15). |

 | | steinitzfan: 31...Qb5. I'm going to have to remember -- Look for the long moves. Look for the long moves. It's target fixation. There's so many tactical ideas going on there in the center that checking out a promising pin is hard. I'm not sure White couldn't have contained his losses a little better, but I think the game is pretty much decided. |
|
| Sep-15-16 | | WorstPlayerEver: <patzer2>
Yes, but 32 Ke2 Ne1 is indeed much stronger. |

 | | PawnSac: < WorstPlayerEver: <patzer2>
Yes, but 32 Ke2 Ne1 is indeed much stronger.> WPE, if Ke2 Ne1 Kxe1 Qxd3 black is up the exchange, but if Ke2 Qxd3 Kxd3 Ne1+ K-any Nxg2 black is up a whole rook!! and patzer2, u r right. c4 was pointless. ..Qb5 Qxf3 Qxd3+ Kg2 Qb1 Qe2 Qxa2 with the advance of the Q-side pawns is the sensible line. white is still losing, but it's better than what he played |

| Sep-15-16 | | YouRang: <steinitzfan: 31...Qb5. I'm going to have to remember -- Look for the long moves. Look for the long moves. > Yep. Puzzles missed are puzzles to learn from.
I usually scan the board to look for tactical ideas. In this case, noticing that the white rook and king are on the same diagonal should have inspired a search for a piece that can hit a light-square diagonal -- and the only such piece for black is the queen. Is there a viable way to get the queen on that diagonal? Yes, if I push the f-pawn... Such thinking often produces results, but today my "scan" was too narrowly focused. |

| Sep-15-16 | | mikealando: "Alekhine was one of the greatest attacking players and could apparently produce combinations at will. What set him apart from most other attacking players was his ability to see the potential for an attack and prepare for it in positions where others saw nothing." Wikipedia Alexander Alekhine |

| Sep-15-16 | | King Harvest: I saw Qb5 (after some looking) and knew it had to be the key to the puzzle, but in the process I developed delusions of delivering mate via Qb5# (after somehow deflecting the rook) -- It can't be done of course but I subconsciously convinced myself this was a puzzle that had to be solved with a tricky mate (rather than just a position won via <threats> of tricky mate), so I gave up. The blinders we put on ourselves are the hardest to see through. |
|
| Sep-15-16 | | Clodhopper: The hallmark of Thursday puzzles - I can pretty much figure out what the first move has to be, but I can't see the second move! |
