An absolute classic brain teaser



F. Stamma,

White to move and ... No computer analysis please. This is a good one. Good luck in finding the solution.

Think I have seen this one before. In any case, it's Zugzwang after 1. Rd1+ Rg1 2. Rf1. It doesn't matter whether Black takes on f1 or not. White wins in either case by promoting the a-pawn. OK, so it's not an
a-pawn yet.

1. rd1 rg1
2. rf1 rxf1
3 kxf1 a5
4. bxa5 b4
5. a6 b3
6. a7 b2
7 a8 = B mate

1Rd1+ Rg1 2Rf1!! is zugzwang and mate in a few, when white's a pawn promotes.

I don't think I need a computer here:-)
This is obviously about zugzwang. First create a pinned rook:

1. Rd1+ Rg1
2. Rf1!!

The obvious place to put it.
Either black plays Rxf1+ Kxf1 now or delays it, this continues with a5 bxa5 b4, and ends with a8=Q#.

Mate in 7 moves.

A neat mate in 6 :)

1. Rd1+ Rg1
2. Rf1+!! Rxf1
3. Kxf1 a5 (zug zwang!)
4. bxa5 b4
5. a6 b3
6. a7 b2
7. a8=B+#

1. Rd1 Rg1
2. Rf1

Alright...I think I got this one:
1. Rd1+ Rg1
2. Rf1!

No matter what, white will promote
the b pawn after taking the black
a pawn and mate.

1Rd1ch rg1 2Rf1 now child's play

Looks easy, coz what can black do after 1. Rd1+ Rg1 2.Rf1! and black is in zugzwang, and can be mated with h8=L+ and mate in one!(cooler than h8=Q+ ..)

Remove the rooks and black is virtually stalemated but actually loses.
So Rd1+ Rg1, Rf1!
Then whether they trade or not, ...a5, ba b4, a6 b3, a7 b2, a8B# is forced.

1.Rd1+ Rg1
2.Rf1!! Rxf1 (1..a5 2.bxa5 b4 3.a6 and white will promote first with check)
3.Kxf1 a5
4.bxa5 and white wins by promoting first with check

Took me like 30 sec. to a minute

I remember this puzzle well. It is a classic in terms of age and theme, but not that difficult if you have seen the two main themes many times. The real issue is how to get the rooks off the board or to tie down black's rook, but that isn't hard to see either:

1. Rd1 Rg1
2. Rf1 and black will eventually be forced to play a5 allowing bxa5 and white will make a new queen or bishop with mate at a8 before or after black exchanges the rooks at f1.

Without rooks on the board, While wins with Kf1 and the pawn race after Black's …a5 with checkmate from a8 upon promotion (queen or bishop).

Therefore, Rd1+, forcing …Rg1, then Rf1, and the rest follows.

Doesn't look too tough. White checks and then exchanges (or pins) the rook on f1 creating a zugswang for black who must move his a-pawn. But White queens with checkmate one move ahead of Black. But cool!

Pretty obvious for a brain teaser. 1. Rd1+, Rg1; 2. Rf1, Rxf1+; 3. Kxf1, a5; 4. bxa5, b4; 5. a6, b3; 6. a7, b2; 7. a8=Q mate.
