1. g3 (to limit the squares of
the bishop.) Kf8 2. Nc4 Bb8 3.
Rb5 wins a pawn. (if 2. ... Bd4
then 3. Rc7 wins the pawn on a7
after the knight moves) Move like
2. ... Bc3+ 3. Kf1 delay things
but don't help much.

1. g5! with the indirect attack on
h3 by the bishop
on e6. If 1. ... Rg3+ 2. Kf2
and black has two pieces hanging.
If instead
1. ... Rh5 (pinning the pawn)
2. Rf5 pinning the knight. 2. ...
Ke7?? 3.
gxf6+
3W0198
1. Qb2+ f6 2. Rxf6 forced
resignation. White threatens 3.
Rxf8 mate so if 2. ... Kg7 then at
the very least white has Rf5+
winning the blackqueen but he can
also play for mate with moves like
3. Rxg6+ eventually leading to
mate.

3W0199
The easy way is 1. c7! Now if
either piece captures white wins a
piece. If instead 1. ... Re8 2.
Rxe5! wins a pieces because if 2.
... Rxe5 3. c8=Q. I have
determined that 1. Rxe5!! and 1. a5
also work, but they are more
complex.

1. Kc6 and now the bishop must
move away from the
king. If it moves to e7, f8,
e3, or f2 then a series of checks
will win
the bishop by Qe4+ and then Qf5+
or Qf3+. If Ba7 then Qb5+ and then
Qa5+
wins the bishop. If Bg1, Qd2+
Kc4 Qc1+ wins on move 3.
_____
3W0207
White can queen his pawn if he can
stop the bishop
on h4 from guarding the d8
queening square. so 1. f4!
threatens 2. f5+
forcing the king to f6 blocking
the bishop If 1. ... Bf6??? 2.
f5 mate!
if 1. ... Be7 then 2. Nxe7 wins
and queens the pawn on move 3.
3W0210
Although white has a good material
advantage here,
it becomes much more decisive
once the black pawns start to drop,
which
also gives white passes pawns.
So 1. Rg4+ and there is no good way
to
defend the h6 pawn. 1. ... Kf7?
2. Bg6+ or any other move by the
king and then 2. Rg6 wins the
black pawn. If 1. ... Kh8 2. Rg6
h5
3. Rh6+ wins the pawn and gives
white two passed pawns on the
kingside.
