White to move. How should White proceed?
5rk1/p7/PpRp1npp/3Pp1q1/4P3/5B1P/5QP1/6K1 w – – 0 1
Could this be an incident of ‘poor queen alert’ ?! 1.h4 seems to force black to give a knight. In both 1. .. Qf4 2.g3 Nxe4 3.gf or 1.h4 Nxe4 2.Bxe4 (just not 2.hg? Nxf2 3.Kxf2 e4) Rxf2 (Qg4 3.Bf3) 3.hg black gets two pawns in return but white will win one back and be able to convert the resulting passer with the help of the extra piece, right ?
1. h4! Qf4
2. g3
and the queen is trapped.
Well, it seems that after 1.h4 Qf4 2.g3 the Black Queen is simply trapped!

1. Qf2-c2

h4
1.h4 literally shouts at you:
1. h4 Qf4 (alternatives below)
2. g3 Ne4 (Ng4 3.gf4+-)
3. gf4 Nf2
4. Kf2 should win for white.
At move 1, black could try Ne4 or Ng4, but neither saves the game:
1. h4 Ne4
2. hg5
If white plays Be4, I like white’s edge, but I don’t like the complexity. Continuing:
2. …..Nf2
3. Kf2 e4
4. Rd6 ef3 (hg5 5.Rd7+-)
5. Rg6 Kh7 (Kf7 6.Rf6+-)
6. Rh6 Kg7
7. gf3 should be an easy win for white.
First, move the white pawn on your extreme right up one step. then you will get to move its neighboring next white pawn on the left one more step(forced). The result will be the capturing of the black queen !! If however,as an extreme defence, black tries to capture one white pawn with its knight attacking white queen, then both queens will be off the board and black will loose the knight thus a peice short in the end game and white will win with rook and bishop against just one black rook.
The Black Queen is trapped. 1.h4 Nxe4 or Ng4 2.hxg5 Nxf2 3.Kxf2
There are many variations but in the variation that is the best case scenario for Black, after exchanges Black comes out down a piece.
Maybe h4, and catch the queen.
1. h4 Qf4
2. g3 Nxe4
3. gxf4
(3. Bxe4 Qxf2+ 4. Kh1 Qf1+ 5. Kh2 Rf2+ 6. Bg2 Qxg2#)
3… Nxf2
4. Kxf2 Rxf4
5. Ke3 g5
6. hxg5 hxg5
7. Rxd6
Now white has a serious problem with all the pawns that black can advance. White still can win given the the advantage of his very mobile bishop and black’s slightly more vulnerable king, but it won’t be easy.
Yancey, where you say “should be an easy win for white”, I agreed initially, but, trying to play it out, I didn’t find a winning line. I ended up in a situation where the black rook was chasing the white king all over the board but unable to pin it down. I let Fritz 13 compute away on it for a couple of hours and it didn’t find one either, though it managed to capture all of black’s remaining pawns.
7. g3 {Easy win for white?}

After 27 moves, it achieved this position: FEN “R7/P5k1/2K3P1/8/8/8/r7/8 b – – 0 27” and was making no progress since the black rook merely was chasing the white king all over the place, never able to pin it down – the same problem that I found. After 64 moves it ended up in this position:
FEN “R7/P5k1/6P1/8/8/8/r2K4/8 w – – 0 65”. Must be a draw. Before long the 50 move rule would kick in.
If you or any of the other followers of this blog find it interesting, see if you can find a winning line from move 7 above. I’m stumped.
Craig,
I looked at your last comment, and you have my move 7 wrong- 7.gxf3 is the correct move, not g3. Put that into Fritz, and let me know what it says. In any case, I was probably a bit hasty in even claiming my line was easy to win, but I was lazy and not all that willing to take it any further. It looks like white should win, though, with the connected passers on the g and f files, along with the advance passer that ends up on d6 eventually.
Sorry, Yancey, to have made the transcribing mistake. Must be dyslexic. But, you’re right that, with the connected pawns on the g and f files, a win for white is more probable. Fritz, with a little help from me at 10… Rd4, computed the following analysis:
1. h4 Nxe4
2. hxg5 Nxf2
3. Kxf2 e4
4. Rxd6 exf3
5. Rxg6+ Kh7
6. Rxh6+ Kg7
7. gxf3 Rf5
8. Rc6 Rxd5
9. Rc7+ Kg6

18. Ra8 Rxf4
19. a7 Ra4
20. Rg8+ Kf7
21. a8=Q Rxa8
22. Rxa8 b5
23. Ra6 Kf8
24. Rb6 Kg7
25. Rxb5 Kg6
26. Kc7 Kh5
27. g6+ Kg4
28. g7 Kf3
29. g8=Q Ke4
30. Qc4+ Kf3
31. Rf5+ Kg3
32. Qe4 Kh3
33. Qf3+ Kh2
34. Rh5+ Kg1
35. Rh1#
Fritz’s preference was to play 10… Rd1 rather than Rd4, which made a win easier for white. Also, I threw in a few what ifs to show why black made a few moves that were less obvious:
10… Rd1
