 | | Phony Benoni: We seem to be having a theme this week of the first move or two being obvious, before the stinger. Perhaps the most famous game utilizing this ♕+♗ attacking set-up was the classic Alekhine vs Yates, 1923. |
|
| Jun-08-13 | | Moonwalker: Ten checks in a row before the finishing blow!
Beautiful attack! |
|
| Jun-08-13 | | s0030135: I think 42. ... Qg4+ 43.Kh2 Be5+ 44.Kh1 Qh3+ 45.Kg1 Bd4+ 46.Rf2 Qg3+ would be a simpler winning line. |
|
| Jun-08-13 | | Dr. J: W Michel vs Rubinstein, 1926 is another fine game with this motif. |
|
| Jun-08-13 | | Infohunter: <bright1: Tremendous attack by Emanuel. The finish would be 48. Kg3 Qg4+ 49. Kh2 Qxh4#.> White could prolong the game by choosing to give up his Queen with 48.Qe3, but after 48...Qd2+ his game is hopeless. |
|
| Jun-08-13 | | Yogi Darwin: Saw it up to but not including the brilliant sacrifice of the second rook. Queen, bishop, and pawn on h5 were sufficient to get the job done. |
|
| Jun-08-13 | | patfoley: I also saw the more elegant line of s0030135. Possibly Berg was short of time and went for blunter force. |
|
| Jun-08-13 | | bachbeet: Saw the first two moves but didn't think it led anywhere. I was so wrong. |

| Jun-08-13 | | abuzic: 39...Rxf3+ 40.Rxf3 Rxf3+ 41.Kg2 Rg3+ 42.Kxg3 <42.Kh2 Qg4> 42...Qg4+ 43.Kh2 Be5+ 44.Kh1 Qh3+ 45.Kg1 Bd4+ 46.Rf2 Qg3+ 47.Kh1 Bxf2, nothing can stop ...Qh3# or Qg1#.

| Jun-08-13 | | gofer: This looks like a simple start and then an elegantr finish. Black brings
three pieces around the king, but ironically it is Ph5 that makes the
combination work...
<39 ... Rxf3+>
40 Kg2 Rf2+ mating
<40 Rxf3 Rxf3+>
<41 Kg2 Rg3+!!>
A beauty!
42 Kf1 Rg1#
42 Kh1 Qxe1+ 43 Kh2 Qg1#
42 Kh2 Qg4 43 Rc8+ Qxc8 44 Kxg3 Qg4+ 45 Kh2 Be5+ 46 Kh1 Qh3+ 47 Kg1 Bd4+ 48 Qe3 Bxe3# <42 Kxg3 Qxe1+>
Now at this point the white king is really struggling to find anywhere to move to! 43 Kg2 Qxe4+ 
43 Kf4 Be3+/Qe3 44 Kf3 Bxh6 
43 Kf3 Qf1+ 44 Kg3 Be5+ 45 Qf4 Bxf4#
43 Kh2 Qg1+ 44 Kh3 Qg4+ 45 Kh2 Be5+ 46 Kh1 Qxe4+
<43 Kh3 Qf1+>
The final mating dance by the queen and bishop is perfect... 44 Kh2/Kg3 lead to wins for black as above...
<44 Rg2 Qf3+>
45 Rg3 Qh1#
<45 Kh2 Be5+>
46 Kh1 Qf1+ 47 Rg1 Qh3#
<46 Kg1 Qd1+>
<47 Kf2 Bd4+>
<48 Kg3 Qg4+>
<49 Kh2 Qxh4#>
~~~
Yep. Perhaps a little easy for a Saturday?! Or is that just because
I got it for once...? |
|
| Jun-08-13 | | morfishine: Very nice attack and game by Black
I was able to work through 39...Rxf3+ 40.Rxf3 Rxf3+ 41.Kg2 and was particularly pleased to have found <41...Rg3+> 42.Kxg3 Qxe1+ 43.Kh3, but here I strayed from the text with <43...Qh1+> instead of 43...Qf1+ and thought I won the White Queen with 44.Kg3 Be5+ 45.Kf2 Qxh4+ 46.Ke3 Qg3+
47.Ke2 Qg2+ 48.Kd1 Qf1+ 49.Kd2 Bf4+
**********
PM: Now I see that White improves with 48.Kd3 :( |
|
| Jun-08-13 | | stacase: How far are we supposed to see these things? I went move for move until 43...Qf1+ I would have moved 43...H1+ |
|
| Jun-08-13 | | mistreaver: Saturday.Black to play. Very difficult. 39?
At first sight, black's first move is kinda obvious:
39... Rxf3+
40 Rxf3 Rxf3+
41 Kg2 Rg3+ and now:
A)
42 Kxg3 Qg4+
43 Kh2 Qg1+
44 Kh3 Be5
45 Rg2 Qh1+
46 Rh2 Qxh2 mate
B)
42 Kh2 Bg1+
43 Kg1 Rh3+
44 Kg2 Qxg4+
and black will win.
I have no time for more detailed analysis, so time to check. I think Rg3 IS the shot.
-----------
Yes of course, first i calculated winning line but stoped "because" of Rf2 defence that loses instantly. And i agree that Qxe1 is much cleaner kill.
At least my second line wins, but instead of sacrificing everything, black has Qg4 and there is no check on c8. |

| Jun-08-13 | | James D Flynn: Both Ks appear to be threatened but if it were White’s move he could consolidate by 40.Rd3 Qa1 41.Ke2 and everything holds and he threatens Rc7 with at least a perpetual.
39…….Rxf3+ (the only way to make progress)40.Kg2(if Rxf3 Rxf3+ 41.Kg2 Rg3+ 42.Kxg3 Qg4+ 43.Kh2 Be5+ 44.Kh1 Qh3+ 45.Kg1 Bd4+ 46.Rf2 Qg3+ 47.Ng2 Qxf2+ 48.Kh2 Be5+ 49.Nf4(if Kh1 Qf1# or if Kh3 Qg3#) Bxf4+ 50.Qxf4 Qxf4 and White is a Q up in the endgame) Rf2+ (not Rxb3 41.Qxg6+with a perpetual check)41.Rxf2 Rxf2+ 42.Kg3 or Kh3(if Kg1 or Kh1 Qxe1#) Qg4#. |
|
| Jun-08-13 | | agb2002: Black has a bishop for a knight.
The first idea that comes to mind is 39... Rxf3+, taking advantage of the pinned knight: A) 40.Rxf3 Rxf3+ 41.Kg2 (41.Rxf2 Rxf2+ 42.Kg1 Qxe1#) 41... Rg3+ A.1) 42.Kxg3 Qxe1+
A.1.a) 43.Kh2 Be5+ 44.Kg2 (44.Kh3 Qh1+ 45.Rh2 Qxh2#) 44... Qxe4+ and 45... Qxc2 - + [B+P]. A.1.b) 43.Kh3 Qh1+ 44.Kg3 (44.Rh2 Qf3#) 44... Be5+ 45.Kf2 Qh2+ and 46... Qxc2 wins material, keeps the attack and there's no perpetual. A.1.c) 43.Kg2 Qxe4+ is similar to A.1.a.
A.1.d) 43.Kf3 Qf1+ 44.Kg3 (44.Rf2 Qxf2#) 44... Be5+ and mate next. A.1.e) 43.Kf4 Qe3#.
A.1.f) 43.Rf2 Qxf2+ 44.Kh3 Qf1+ and mate in two.
A.2) 42.Kh1 Qxe1+ 43.Kh2 Qg1#.
A.3) 42.Kh2 Qg4 43.Rc8+ (43.Kh1 Rg1+ 44.Kh2 Qg3#) 43... Qxc8 44.Kxg3 Qg4+ 45.Kh2 Be5+ 46.Kh1 Qh3+ 47.Kg1 Bd4+ 48.Qe3 Bxe3#. A.4) 42.Kf1 Rg1#.
B) 40.Kg2 Rf2+ 41.Rxf2 (else mate next) 41... Rxf2+ and mate next. |

| | LoveThatJoker: <stacase: How far are we supposed to see these things? I went move for move until 43...Qf1+ I would have moved 43...H1+> Opting for 43...Qh1+ is a fully winning, although less precise, alternative. Therefore, you can claim to have solved the puzzle correctly: you found a comprehensively winning line. All this objectively true, bonus and style points/fully-justified bragging rights to the in-form fellow kibitzer(s) who found/will find the mating line after 43. Kh3 Qf1+! LTJ |

| | LoveThatJoker: <stacase> My pleasure, man! LTJ |
|
| Jun-08-13 | | jancotianno: I found 42... Qg4+ instead of what was played in the game and it turns out it is quicker. For some reason I didn't even consider Qxe1+. |
|
| Jun-08-13 | | The Last Straw: It seems like white had an advantage until the pawn advances. |
|
| Jun-08-13 | | Patriot: 39...Rxf3+ doesn't look risky.
40.Rxf3 Rxf3+ 41.Kg2 Rg3+ 42.Kxg3 Qg4+ and black seems to have a good attack. A draw seems to be the worse case scenario. |
|
| Jun-09-13 | | M.Hassan: "Very Difficult"
Black to play 39...?
Black has a bishop for a Knight. Considered equal.
Taking the f pawn seems to be obvious and the working way of staring the attack: 39............Rxf3+
40.Rxf3 Rxf3+
41.Kg2 Rg3+!!
42.Kxg3 Qg4+
Black succeeds in confing the King to h file at least for time being
43.Kh2 Be5+
44.Kh1 Qh3+ (not...Qxh4+ to push the King to white square
) 45.Kg1 Bd4+
46.Rf2 the only defending move
46...........Qg3+
47.Kh1 Bxf2 threatening mate on g1
48.Qxg6+ Qxg6
Black's win is no doubt |
