1.Bxa7+ Kc7 2.Bb6+ Kb8 3.Rb4 and Bc7+
ck ck …. mate
First of all, forget Bxf6, doesn’t work because of the resource Ka8.
More efficiant is to eliminate a7 pawn:
1. Bxa7+
with 3 answer alternatives:
a)
1. … Qxa7
2. Rb4+ Ka8 (Kc7 Qxa7+ Kc/d8 Rb8#)
3. Qxc6+ Qb7
4. Qxb7#
b)
1. … Ka8
2. Bc5+ Kb8
3. Rb4+ Kc7
4. Bb6+ Kb8
5. Bd8+ Qb7
6. Qxb7#
c)
1. … Kc7
2. Bb6+ Kb8
3. Rb4 (threats Bd8+) Qb7
4. Bc7+ Kxc7
5. Rxb7+ Kc/d8
6. Qa8#
Bd4 x a7
1.Bxa7+! Qxa7 2.Rb4+ Ka8 3.Qxc6+ Qb7 4.Qxb7#; 1…Kc7 2.Qb6+ Kc8 3.Qb8#; 1…Ka8 2.Rb4! and mate in 2 (or 2.Bb8+ Kxb8 3.Rb4+ Kc7 4.Qb6+ Kc8 5.Qb8#).
Bxa7+ QxB
Rb4+ Ka8
Qxc6+ Qb7
QxQ++
Whatever Black does in his first move, the Re4 gets to b4 to give a deadly check:
1. Bxa7+ Ka8
Alternatives:
A)
1. … Qxa7
2. Rb4+ and now
a)
2. … Ka8 3.Qxc6+ Qb7 4.Qxb7#

3. Qb8#
2. Be3+ Kb8
3. Rb4+ Kc7
4. Bb6+ Kb8
5. Ba5+ Qb7

a precise indication of the possible variations (max. 6 moves):
1. Bxa7+ Qxa7

3. Qxc6+ Qb7
4. Qxb7#
2. … Kc7

greets, jan
1 Bxa7+ wins.
Now if 1… Qxa7
2 Rb3+ Ka8
3 Qxc6+ Qb7
4 Qxb7#
elseif 1 … Kg8
2 Be3+ Kb8
3 Rb3+ Kc7
4 Qb6+ Kc8
5 Qb8#
Other replies by back are trivial.
Grabbing the pawn grabs my attention because of the quick-calc 1. Bxa7 Qxa7 2. Rb4+ Ka8 (not 2. … Kc7 3. Qxa7+ Kc8(d8) 4. Rb8#) 3. Qxc6+ Qb7 4. Qxb7#. Other options for Black: 1. … Ka8 2. Be3+ Kb8 3. Rb4+ Kc7 4. Qb6+ Kc8 5. Qb8#. 1. … Kc7 2. Qb6+ Kc8 3. Qb8#
1.Bxa7+ Qxa7 2.Rb4+ Ka8 3.Qxc6+ wins
1) B x a7+ Q x B
2) Tb4+ Ka8
3) Q x c6+ and white wins.
1. Bxa7+ Qxa7
2. Rb4+ Ka8
3. Qxc6+ and mate
if
2. .. Kc7
3. Qxa7+
if
1. .. Ka8 or Kc7
2. Bb6+ Kb8
3. Ra4, and mate on a8
