OK, back to work. Here Black's only desire is to win one of the knights. Be careful what you wish for... <1.Nd2+ Kd3 2.Ne1+ Ke2 3.Bb5+ Kd1> (Not yet, capturing either knight allows a winning fork with 4.Nf3+.) <4.d7 Bxd7 5.Bxd7 Be5+ 6.Kb1 Bc3 7.Ne4 Bxe1 8.Bg4#!>

This looks easy. Just sacrfice some stuff and Black can't stop the f-pawn. <1.f5+ Kxf5 2.Nh6+ Rxh6 3.f7 Ng5+! 4.Bxg5 Kxg5> (Ah-ha!. I see the trick--5.f8Q Rf6+. Well, we know what to do about that.) <5.h4+! Kg6!>

(Hmmm. We seem to have goofed. Making a queen is stalemate, and a rook does no more than draw. Any other volunteers?) <6f8B!>
One can just hear the rook screaming, "Don't leave me! Don't leave me!" But to no avail... |

If any of you find White's second move without computer assistance, I will be impressed. I might even be slightly impressed if you find it with computer assistance and don't think your analyst is suffering from the horizon effect. <1.Nb3 d3 2.Bg5!!!>
Certainly looks futile.
<2...hxg5 3.Kh6!! c1Q 4.Nxc1 d2 5.Nb3 d1Q>
 click for larger view
<6.Bc2! Qg4! 7.Bf5!> And all is revealed. 2.Bg5 sealed off the queen's escape along the g-file, while 3.Kh6 kept the king safe from checks as it guards h5. Meanwhite, Black's queen is face with forks and skewere all over the place, such as 7...Qa4 8.Bd7+ Kxd7 9.Nc5+. Therefore: <7...Qd1! 8.Bc2!>
And draws by the papparazzi maneuver! |

According to endgame theory, B+2Ns normally defeats B though there are exceptions. Will this be one of them? <1.N6c7 a1N+>
Necessary to stop Bb6#.
<2.Kb2 Nb3!>
Since the knight cannot be salvaged, Black goes for stalemate. <3.Kxb3 Be3! 4.Bh2 Bg1 5.Bf4! Be3>
 click for larger view
This is getting annoying, but what can White do about it! <6.Nb6!!>
Simply winning after 6...Bxb6 7.Bd2#, 6...Bxf4 7.Nc4#, or 6...Kxb6 7.Nd5+. And that's why 5.Bf4 got an exclam--the Black bishop had to be on precisely the e3 square for the last line to work. |

Sometimes you just have to attack.
<1.Nf6>
Keeps the king away from the safety of g4, threatens 2.e4+ Kxf6 3.Bg5#--and there's this little matter of an en prise queen to deal with as well. <1...Kxf6 2.e4 e5>
Ah, we've gotten into an "e4 e5" line. Maybe there are chances after all. <3.Bg7+ Ke6 4.f5+ Kxd6 5.Bf8+ Qe7>

Now that's progress! All we have to do now is take the queen--and lose the pawn ending. Oh, wait... <6.f6! Qxf8>
Stalemate. |

So, the question is--how do we lure the Black pawn to f5? <1.Rc4 b2 2.Rxc2 bxa1Q 3.f3+ Kg1 4.Kh3 Nxe3 5.Rh2>
 click for larger view
A kind of mutual zugzwang. Black can't move the queen due to knight forks, the Ne3 must guard Rg2#, and the Nb1 must stop Rh1+ winning the queen. On the other hand, White can't keep his position intact either, and Black has more pawn moves available. <5...f5 6.f4 d5 7.a3! Qxa3> Well, what else?
<8.Rg2+! Nxg2>

Not as easy as it looks, as 1.axb7 is answered by 1...Bf8+ and 2...Bd6. The play revolves around taking this resource away from Black. <1.d4+ Ke4>
1...Ke6 2.Bg4+ f5 3.Bxf5+, and Black's king must give up protection of d6 or block the bishop with 3...Ke7. After the text, 2.axb7 is still premature because of 2...Bxd4+ and 3...Be5. <2.Bf3+ Kd3>
Still too early: 3.axb7 Bxd4+ 3.Kd6 f6 and 4...Be5+.
<3.Be2+ Ke4 4.axb7! Bxd4+ 5.Kc4! Be5>

So Black stops the pawn, while White...
<6.Bd3#!>
...stops Black.

It's easy enough to skewer the king and queen. You just have to get them on the right squares. <1.Qd4+ Ka3>
1...Ka5 2.Qd8+ Kb4 3.Qf8+ and 4.f7 wins.
<2.Qa1+ Kb4 3.f7! Qxa1 4.f8Q+! Ka5> 4...Kc3 5.Qf6+ wins the queen along the diagonal.
<5.Qd8+ Kb4 6.Qd6+ Ka5 7.b4+ Ka4 8.Qxa6+> Winning the queen along the file instead. |

Another one of those B+2Ns vs. B endings. This time, the defense holds. <1.Bf2 Bxb4 2.d6 Nxd6+> 2...Bxd6 3.Kf3 Nf4 4.Bg3 draws.
<3.Kf3 Ne1+ 4.Ke2 Nc2 5.Kd3 Na3 6.Bd4+ Kg6 7.Bc3>

An older, distant cousin of the manuever which has become known as "Mitrofanov's Deflection". <1.Rg6 Nf6 2.Qh6+ Kf7 3.Rxf6+ exf6 4.Qh7+ Ke6 5.f5+ Kd6 6.c5+ Kd5>  click for larger view
Now what? 7.Qf7+ Ke4 allows the king to escape, and 7.Kd3 Qa6+ leads nowhere. What else is there? <7.Qg8+!! Qxg8 8.Kd3!> And Black cannot stop 9.c4#!
For comparison, here is the climactic moment of Mitrofanov's famous study from 1967, starting after Black's 6th move:

<7.Qg5!! Qxg5+ 8.Ka6 Bxa7 9.c7!!> Wow. With 2 pawns vs. Q+B+N White plays a quiet move, threatening two mates. <9...Qa5+ 10.Qxa5 Kb7 11.bxa7> And one of the pawns queens.

Nov-23-06
 | | Phony Benoni: <siilarsi> Thanks for the kind words. I would have to agree that coffee does warp the brain, which is why I never touch the stuff. However, in my case, such abstinence doesn't seem to have helped much. |

Considering the position of the White king, you can put your ChessBucks on a stalemate. But the actual method is pretty. <1.Bg1 a2 2.Bh7! b1Q 3.Bd4+ Qb2 4.Bh8!>

And Black can spend the rest of the time control deciding whether to stalemate White with 4...Qxh8, or get mated after any other move. |

In which Black is cursed with a succession of bad choices. <1.Bb5+! Qxb5>
(1...Nxb5 allows 2.Nc5+ and mate next move, while 1...Kxb5 runs into 2.Nd6+.) <2.Nc3+ Kxa3 3.Nxb5+ Nxb5>
 click for larger view
And Black's knight will be able to stop the h-pawn. Unfortunately, it can't stop the knight as well. <4.h6 Nd6 5.Nc4+!>
And wins, one way or the other.
All very neat and clean-cut. However, that old spoilsport tablebase points out that, in the second diagram, White wins more easily with 4.Nf5, cutting off Black's knight from the d6 square. 4.Nc4+ and 4.Nc2+ work as well, though a good deal trickier. |

1...g6 2.Kc7 Bd8 3.Bd4, and the bishop is going nowhere. <2.Kb7 Bd8 3.Kc8 Be7 4.Kd7 Bf8 5.Be3+!> Not so fast, big guy!
<5...Kc7 6.Ke8 Bg7 7.Kxf7 Bh8 8.Kg8> And that's that. Note, by the way, the g3-pawn's reason for existence; without it, Black could draw with 8...Kb3. Then again, Troitzky might have been able to find a win. Remember this famous composition by him?

It's a good exercise to determine why these moves were necessary; for instance, Black had to delay ...e3 until his king was within reach of d2. Now, it seems White has only bad choices: 4.fxe3 fxe3 5.Kf4 Kd2 6.Kf3 f4!, with zugzwang.
4.f3 Kd2 wins easily
4.Kxf4 exf2 and the pawn promotes.
<4.Kxf4! exf2 5.Ke3!!>

The point: 5...f1Q or 5...f1R are stalemate! Where did that come from? <5...f1B>
He has to promote to something or lose the f2-pawn, and after 5...f1N+ 6.Kf4 Black can no longer protect the vital final pawn. <6.Kf4 Bh3 7.e4>
and draws, as the last pawn comes off. |
