1. Qf5+ and now if 1. ... Ke8 2.
Qc8+ Kf7 3. Qxh8
Kxg6 4. Qxd4 with a won
position. If instead 1. ... Ke7,
then 2. Re6+
Kd8 (Kd7 is worse because of
Rh6+) 3. Qd5+ Bd6 (so as to be
able to play
kd7) 4. Rxd6+ cxd6 5. Qa8+
with a skewer.

There might be other solutions, but
a neat mate in 5
is 1. Bc7+ Kxc7 2. Nd5+ and
black can flee to 3 squares all of
which are
bad. 2. ... Kd8 3. Rxc6 and
then 4. Rd6 mate. 2. ... Kb8 3.
Qxc6
forces mate. So 2. ... Kb7 3.
Qxc6+ Ka6 4. Nb4+ Ka5 5. Qa4
mate.

1. Qf5+ and now if 1. ... Ke8 2.
Qc8+ Kf7 3. Qxh8
Kxg6 4. Qxd4 with a won

Kd8 (Kd7 is worse because of
Rh6+) 3. Qd5+ Bd6 (so as to be
able to play
kd7) 4. Rxd6+ cxd6 5. Qa8+
with a skewer.
Thanks to Eon on FICS.

Apparently the best way is to just
overwhelm black with pawns. The
white king doesn't really
participate much in the attack. 1.
b6 and not Kc8 2. b7+ Kb8 3. d7
Kc7 4. d8=Q+ Kxd8 5. b8=Q. If
instead 1. ... Ra5+ then the king
flees and he
plays b7 (followed by c7) at his
convenience.

Crafty (comptuer) vs. Grand Master
Heine in a 3 minute game at the
Internet Chess Club. 1. Qf7!
Black resigns. i.e. 1. ... Kb8 2.
Bxa7+ Ka8 3. Bc5+ Kb8 4. Rb1+
forces mate. The threat is 5. Qb7
mate. Black can give up two pieces
to delay it, but it hardly
matters.
If 1. ... a5 2. Rxa5! wins
_____

the position is complicated. White
can win the
exchange by taking on e7 but
there is better. he would like to
play Qh4
threatening mate but the
response of f6 threatenes Rh7. It
appears that
the best is 1. Nxd8! Qxd8? 2.
Qh4 f6 3. Bxh6 Rh7 4. Bxd8 Rxh4+
5. Bxh4
Other variations are possible.
