if Kb7 Rb8 followed by Nc6+ wins the queen.

Not as tough as some of the others recently. But still, important idea.

5.h5 and the black king is one tempo away from stepping into the runaway pawn’s queening square. If only he could end up on d8 instead. (-;

black king on a7 or b8 allows a knight-fork. i think white should trade both pieces for the queen and then walk the h-pawn for a queen himself. it could work like this:
1. Rd8+ Kb7
2. Rb8+ Kxb8
3. Nc6+ K
4. Nxa5 bxa5
5. h5
black can take the h-pawn instead of the knight, but being a piece up is also nice. jan
the position of the knight, king and queen is a pattern that immediately suggests “fork”. This can be achieved with 1. Rd8 Kb7 2. Rb8 Kxb8 3. Nxc6.
A quick safety check is required on the endgame 3…Kc8 4. Nxa5. The King is outside the square of the h-pawn, so the pawn endgame is lost after 4…bxa5.
There is a lovely interview with Judit on chessbase today.
1. Rd8+ Kb7
2. Rb8+ Kb8:
3. Nc6:+ Kc8
4. Na5: wins b/c of the h pawn
1.Rd8+
a) … Ka7 2.Nxc6+
b) … Kb7 2.Rb8+ Kxb8 3.Nxc6+
(2… Ka7? 3.Nxc6#)
(2… Ka6? 3.Ra8+)
After capturing Black’s queen, White will capture Black’s f-pawns
(when Black chooses to take on h4) or promote the h-pawn (when Black chooses not to take it).
White’s king should cut off the Black king, or let him go and take the queenside pawns after which
the white queenside pawns will easily win.
1. Rd8+ Kb7 2. Rb8+ Kxb8 3. Nc6+ Kc8 4. Nxa5 gxh4 (4..bxa5 5. h5 and black cannot stop the queening) 5. Nc6 and the resulting end game is a win for white
Due to the passed pawn on h4, White can afford to
indulge in a grandstand display.
1. Rd8+ Kb7
(If 1…. Ka7, then 2. Nxc6+ forking king and queen. Rook up)
2. Rb8+ (I don’t think anyone is going to
throw gold pieces onto the board for
having seen this. It’s just a grandstand
move.)
2…. Kxb8 (or 2… Ka7 3. Nxc6+ again)
3. Nxc6+ (finally get to play that move)
3…. Kc8 (have to try to stop the h-pawn)
4. Nxa5 (don’t forget to take the queen)
4…. bxa5 (have to stop to take the knight)
5. h5 Kd8
6. h6 Ke8
7. h7 Kf8 (one move too late)
8. h8=Q+
So, Black has to try something other than taking the knight
on move 4. Taking the passed h-pawn looks best.
4…. gxh4 but after
5. Nc6 Kd7
6. Nd4 Kd6
7. Nb5+ (Better than Nf5. The knight is needed
in the center and on the queen
side to harass Black’s pawns, and
to guard White’s own pawns. The
White king can gobble up the Black
kingside pawns all by himself, starting
with that little morsel on e4.)
7…. Kd7 (Can’t guard both c-pawn and pawn on
e4 at the same time. This is an
overworked king.)
8. Kf3 (Just about to munch the first pawn.)
8…. c6
9. Nd4 Kd6
10. Kxf4 (My, that was tasty.)
10…. Kc5
11. Nc2 (Nicely keeps the Black king from
approaching.
11…. Resigns (In order.)
Sometimes I really can’t see the wood for the trees.
I worked out the sequence:
1. Rd8+ Kb7
2. Rb8+! Kxb8
3. Nxc6+ Kc8
4. Nxa5 bxa5
and then was wondering whether white can win it from here, despite being a pawn down. Took me a good 2-3 minutes to notice the killer 5. h5!! – a pawn that the black cannot stop from promoting.
4… gxh4 is no good either. The knight escapes, and black cannot protect all the pawns.
