bd4
Bd4 does the job. Luring the King onto the long diagonal to black’s queening square.
Brit-Mate
Bd4
I would say :
1 Bd4! – Kxd4 (otherwise no queening possible)
2 b8Q
If 2… g1Q then 3 Qb6+ winning the queen.
the obvious idea is Bd4, so if
Kxb
B8=Q g1=anything
Qa7+ K moves
Qxg1
or
h3
B8=Q h2
Qb7+ K moves
Qxg2
Bd4
If Kxd4
then b8Q, g1Q, Qb6+ and capture the queen in the next move with an easy mate to follow.
1. Bd4
if 1… h3
2. b8(Q) h2
3. Qb7+
and 4. Qxg2 wins
if 1… Kxd4
2. b8(Q) g1(Q)
3. Qb6+ wins
if 1… Kxd4
2. b8(Q) h3
3. Qg3 wins
Maybe Bd4 Kxd4 b8=Q g1=Q Qb6+
1. Bd4 Kxd4
2. b8=Q
if
2. … g1=Q
3. Qb6+ picking the queen
V.P.
I don’t know why no computer analysis. It’s not like they keep track of how many each person gets right, or who got it first. If somebody wants to spoil their own fun, let ’em. But in this case, no computer is needed. 1. B-Q4 is pretty obvious.
1.Bd4 Kxd4 2.b8Q
I think 1.Bd4 Kxd4 2.b8=Q g1=Q 3.Qb6+ (king move) 4.Qxg1.
