Er, white proceed to win or to survive longer?!
Rxh7 followed by rh1 + and either Nf4#(after Kg6) or Ng4+ with mate after Kg8
RH7+
1rxp ch will prevent mate in one.
1. Rxh7+
1. … Kg8
2. Ng5+ Kf8
3. Qf7#
1. … Kxh7
2. Rh1+
2. … Kg6
3. Qh5#
2. … Kg8
3. Ng5+ Kf8
4. Qf7#
it seems to be a checkmate after
1. Rxh7+ Kxh7
2. Rh1+ Kg8 (Kg6, 3. Qh5#)
3. Nd8/g5+ Kf8
4. Qf7#
1. … Kg8
2. Ng5+ Kf8
3. Qf7#
greets, jan
My first intuition was to defend my self against “sudden death” by putting “something” on d4.
Not finding anything reasonable to put there (Nd4? Qxc5), I simply have to try:
1. Rxh7+ Kxh7 (Kg8 Nd4+ Kf8 Rh8#)
2. Rh1+ Kg8 (Kg6 Qh5#)
3. Nf8+ (with a smile) Kxf8
4. Rh8#
2. … Bh4 delays by one.
One could hardly wish it easier…
1.rh7 kh7
2.rh1+ kg8
3.Nd8+ kf8
4.Qf7#
1. Rxh7+, Kxh7 (not taking the rook with Kg8 only makes it worse)
2. Rh1+, Kg8 (2. .., Kg6 3. Qh5#)
3. Nd8+, Kf8
4. Rh8#
1. Rh7+ Kh7 (Kg8 2. Ng6+ Kf8 3. Qf7#)
2. Rh1+ Kg8 (Kg6 3. Qh6#)
3. Ng6+ Kf8
4. Qf7#
Since Black has mate in 2, White must win with constant checks. I think this is a line that wins:
1.Rxh7+ Kxh7 (must take or Black walks into mate via discovered check and Qf7)
2.Rh1+ Kg8 (if 2…Kg6, 3.Qh5#)(Black prolong the game with 2…Bh4 but 3.Rxh4 leads to same end).
3.Ng5+ Kf8
4.Qf7#
1.Rxh7+ Kxh7 2.Rh1+ Kg8
(if 2..Kg6 3.Qh5#)
3.Ng5+ Kf8 Qf7#
Strike fast, hard and continuously:
1. Rxh7+! Kxh7 2. Rh1+ Kg8 3. Ng5+ Kf8 4. Qf7#
Ta da!
1. Rxh7+! Kxh7
2. Rh1+ Kg8
3. Ng5+ Kf8
4. Qf7#
Desparate times call for desparate measures. 1. Rxh8! and the king should have nowhere to hide.
1Rxh7+ Kxh7
2Rh1+ Bh4 to make room for K at f6.
3Rxh4+ Kg6
4Nf4+ Kf6
5Bd4#
After…
1-Rxh7+; Kxh7
2- Rh1+…
All posters so far (unless I have skimmed too quickly through this thread) seem to have missed black’s most tenacious reply:
2-…; Bh4 (clearing the f6 square for the king)
3- Rxh4+; Kg6
4- Nf4+; Kf6
5- Bf4#
Because the solution seemed so obvious at first, it was easy to miss 2…Bh4. I know I did, initially.
Of course I meant to write 5-Bd4# in my previous post.
