RE: Chess problem 68 / Schachaufgabe 68

in #chess6 years ago (edited)

Hello @jaki01

When I see the position I realize that the g5 bishop is being threatened by the pawn. There are 3 possible plays of which I discard Bh4 because I would lose material, therefore, I would have as options Bxe7 or Bxh6. If I play Bxe7, Black does not seem to have any problems, besides Black would have a powerful knight in e4 controlling important squares and after the capture in e7, the black queen could cause problems in the queenside with the move Qb4.

Then, the only play that would allow White to get an interesting attack, and with that advantage, would be the move Bxh6.

  1. Bxh6 gxh6
  2. Bxe4 dxe4
  3. Rg3+ Kh7
  4. Qh6 Rg8 (stopping Kg5+)
  5. Qxf7+ Kh8
  6. Rxg8 Qxg8
  7. Qxe7 and White has a clear advantage. The interesting thing is that all the plays are almost forced.
Sort:  

4. Qh6 is not possible. Did you mean 4. Qh5?

Upss!. Yes, I mean 5. Qh5

OK ... then let's check your variation ... :)

  1. Bxh6 gxh6
  2. Bxe4 dxe4
  3. Rg3+ Kh7
  4. Qh5 what about 4. ... Qe8?

5.. Ng5+!
Black is lost if he takes on g5 with the bishop or moves the king.
For example,
5.. Ng5+ Kg7
6.. Nxf7+ Kf6
7.. Qg6#
or
6.. ... Kh7 (or Kh8)
7.. Qxh6#
or
6.. ... Bg5
7.. Qxh6+ Kxf7
8.. Qh7+ Kf6
9.. fxg5#

In the other hand,
5.. Ng5+ Bxg5
6.. fxg5 Black is lost with any play

  1. Bxh6 gxh6
  2. Bxe4 dxe4
  3. Rg3+ Kh7
  4. Qh5 Qe8
  5. Ng5+ Bxg5
  6. fxg5 Rh8

What now?

7.. Qxh6 Kg8
8.. Rh3 and the mate is unstoppable

8. Rh3 Rxh6 and black wins! :)
