White to move. How should White proceed?
Source: ChessToday.net
h5 gxh
g5!
the creation of a free pawn combined with the threats of the capture of the queen side pawns and/or the penetration of the king is decisive
Nxg6, B takes g6 f5+, followed by king and pawn ending with opposition.
I can not see something spectacular. So the best attempt is:
1. f5+ gxf5
2. g5 hg5
3. hg5 Ke7
4. Kf4 Ke6
5. g6 Kf6
6. g7 Kxg7
7. Kxf5 Kf8
8. Ke6
Black can not provide White to pick Black’s pawns and so to win quite easily.
1. Ne5-d3
–br
I would play 1.f5+! gxf5 forced otherwise White simplify into a won pawn ending
2.g5! hxg 3.hxg c5!? otherwise 4.Kf4! and there’s simply no play left Black will be in zugzwang and will play c5 and this time white takes with the d-pawn. 4.bxc5 forced
And now the real work begins
A)4..b4 5.Nd3! b3 6.Kd2!+- Bc6!? 7.Nf4+ +- and White wins
B)If black does nothing like this then let’s say and keeps the bishop on e8 and the king on e6 then Ne5-d3-b4, puts the king on f4 and then c6! of course the pawn in itself is not a danger but it zugzwangs black. If …K moves Kxf5!+- if bishop moves somewhere else than on g6 then c7 and Kxf5 +- if …Bg6 then the nice Nxd5 gives it all to White !
They may be other possibilities but i think my plan is simple enough.
I have to admitt I moved the pieces 🙂
Shree,
That will lose:
1. Ng6 Bg6
2. f5 Bf5
3. gf5 Kf5
4. Kf3 h5 and it is black that will have the opposition and win.
Asher,
1. h5 gh5
2. g5 hg5
3. fg5 Kf5 is decisive for black.
I don’t really have to time to do a complete analysis of this right now, but black is almost in a state of zugzwang already. This suggest to me that a waiting king move like Kd2, Ke2, or Kf2 might be appropriate. Of the three, I like Ke2 the most since it keeps the question of which side should black move his king to on his shoulders- Kf6 or Kd6? If black, instead:
1. Ke2 h5
2. f5! gf5
3. g5! and white should be able win this since black’s position is completely passive. Continuing:
3. …..Kd6 (f4 4.Nd3 and 5.Kf3)
4. Kf3 Ke7 (only way to get Ke6)
5. Kf4 Ke6
6. g6 Kf6 (what else?)
7. g7!! Kg7 (Bf7 no better)
8. Kf5 c5 (Kh6 9.Kf6,or Kf8 9.Ke6)
9. dc5 and I don’t see how black can hold this.
Ok, got a bit more time:
1. Ke2 Kf6
2. g5 hg5
3. hg5 Ke6 (Kf4 4.Kf3 and 5.Kg4)
4. Kf2 and I don’t see how black stops white’s king from reaching g4. Continuing:
4. …..Ke7 (Kf5 5.Kf3 and 6.Kg4)
5. Kf3 Kd6 (Ke6 6.Kg4)
6. Kg4 Ke6
7. f5 gf5
8. Kf4 and black is in zugzwang- he must give up either the f-pawn or the c-pawn. Giving up the c-pawn is the better defense. Continuing:
8. …..Bh5
9. Nc6 Bg6 (nothing else better)
10.Ne5 Be8
11.g6 Kf6
12.g7! Kg7 (what else?)
And white will win the remaining queenside pawns.
I have to go, but I imagine that
1. Ke2 Kd6 will be no better for black than the line above.
I think, having worked through this, that the key is to keep the long range opposition from the starting position. Black has very few possible moves right from the beginning, and if white can induce black’s king to give way one side or the other, white gains the upper hand to bring his king into a position to penetrate.
f5+ gxf
g5. h5
Kf4 zugzwang for black
Ke7
Kxf5 etc
if g5 hxg5
hxg5 (and as above)
1. f5+ gxf5
2. g5! +- (Zugy-Zugy)
(Very) Bad Bishop!
1. f5+ gxf5
2. g5
must be winning
I think it is logically white who has the advantage and the chance to win. For that he must create a passed pawn, but this is obtained in another way:
1.f5+ gxf5 2.g5, since the bishop cannot move and the white K is going to go to f4. 2…hxg5 3.hxg5 followed by 4.Kf4. The white K can they penetrate after a timely g6.
I think that the winning variaion is :
1.f5+! gxf 2.g5 hxg 3.hxg c5! 4.bxc5 b4 5. c6 b3 6.c7 Bd7 7.g6 b2 8.c8=Q! Bxc8 9.g7 b1=Q 10.g8=Q+ winning
White can get an edge with f5! gf g5 hg hg
the black king can’t approach the g pawn and in fact is running out of good options. White can move in.
1.f5+, pxp,
2.g5, pxp
3.pxp wins
but so does g5 followed later by f5
Gosh, do I have to solve everything? I already fixed the USCF.
f5 gxf5
g5 followed by
kf4
I looked at this for a long time and can’t see anything really decisive. But black doesn’t have a lot of candidate moves, so it looks like maybe a waiting move like Kf3 would cause him problems.
1…h5 2. f5+ gf 3. g5 and white will push the g-pawn, attack the black f-pawn with his K, and eventually harvest the h-pawn and win.
1..g5 2. fg hg 3. hg and the passed pawns will decide.
1…Bf7 2. f5+ gf 3. gf+ Kf6 4. N:f7 K:f7 5, Kf4 Kf6 6. h5 and white wins.
1…Bd7 2. N:g6
1…Kd6 2. g5 h5 3. f5 gf 4. g6 Ke6 5. Kf4 Kf6 6. g7 K:g7 7. K:f5 and the white K has penetrated. White will win without much trouble.
1…Kf6 2. g5+ hg 3. hg Kf5 4. Ng4 and the f-pawn will advance.
1…Ke7 2. g5 h5 3. f5 gf g6 is much like 1…Kd6.
This one is too hard. I want to get the white king through on the kingside. Something like Kf4 Kf6 g5+ (not befor when h4 is possible ) hxg hxg but then Kf5. I guess if black has no counter play we can hop the knight to g3 and then advance.
I’ve been a keen end game player all my life and would play f5+ in a blink of an eye.
1.f5 gxf5 2.g5 hxg5 3.hxg5 Kd6 4.Kf4 Ke6 5.g6 Kf6 6.g7 Kxg7 7.Kxf5 and white wins.
1. f5 gxf
2. g5 hxg
3. hxg Bd7
4. Kf3 Be8
5. Kf4 and Black is in Zugzwang
