Solutions for
Stalemate Means It's Not Check!
|
|
|
|
|
A.
|
1...Qf8+ |
|
B.
|
1...Qg6 |
|
C.
|
1...Qg5 |
A. 1...Qf8+ isn't good because it allows the king to leave the corner.
B. 1...Qg6 is stalemate! White is not in check, but has no legal
moves.
C. 1...Qg5! is best. The white king has two squares to
move back and forth in while the black king moves in for the mate. |
|
|
|
|
A.
|
1...Rb7 |
|
B.
|
1...Ra1+ |
|
C.
|
1...Kc7 |
A. 1...Rb7 stalemate!
B. 1...Ra1+ (leads to mate in three) 2.Kb8 Ra2 (or 2...Ra3, 2...Ra4,
2...Ra5, 2...Ra6 are waiting moves that leave White only one
place to go) 3.Kc8 Ra8#
C. 1...Kc7! 2.Ka7 Ra1#. |

Black gives up the pawn with 1...Kc4 (or Kc5, Kd5, Ke5, Ke4)
1...Kd3 stalemate is no better. 1...Kc3 (or 1...Ke3) wins.
White has only one possible move—2.Ke2 (or 2.Kc2) 2...Kc2
(or 2...Ke2) This keeps the white king out of the queening square,
which Black now protects. White can't stop the pawn from being promoted. |

1...Qc7+! If 2.Qxc7, stalemate. If White does anything
else, then 2...Qxd7 and White is lost.
The perpetual check, forcing the position to repeat three times, works
this way — 1...Qf4+ If 2.Kg1 (or 2.Kh1), then 3...Qc1+ 3.Kh2
Qf4+ 4.Kh1 Qc1+, etc. If 2.g3 then 2...Qxf2+ 3.Kh1 Qf1+
4.Kh2 Qf2+, etc. |
