1. ... , Ne1

Ne1 leaves white without a reply I think.

if Bf1 Rxf2
Bxh3 Rf1 & mate next move

If Qxe1 Rxf2
Qg1 Rf1

If Rxf7 Qg2 mate

I like 1. ... Ne1

It seems fairly obvious from there.

Ncd4. I think Black is better.

,,, Ne1 leaves the rook on f2 hanging and white cannot trade rooks due to the mate on g2

Ravi said...

1. ..., Ne1
2.Nf6+ (a delaying tactic)
(2.Rxf7 Qg2#)
(2.Qxe1 Rxf2 and White cannot stop the mate at g2 and if he tries to protect g2 through Qg1, Black can mate at Qf3)
2...Rxf6 3.Bf5 Rxf5 4.Qd5+ Kh8 5.Bxe5+ Nxe5 6.Qg2 Nxg2 7.Rc3 Qxc3 8.Rxf5 Rxf5 9.h4

Why on earth has nobody suggested Ne1 here?
Now Rf2 can't move, because of either Qg2# or Rf1 Bxf1 Qxf1#.

1. Ne1! Qxe1 (no other option)
2. Rxf2 Qg1/Ne3 (otherwise Qg2#)
3. Qxb2
and having taken a full rook, black is simply up with quality + 2 pawns.

Oh, it's of cource an enforced mate here (seems to be mate in 6):

1. ... Ne1!
Rf2 is fixed and falls next (2. Rd2 Rf1+ 3. Bxf1 Rxf1#/Qxf1#, 2. Rxf7 Qg2#).
And after 2. ... Rxf2 there is no way to defend both Qg2# and Qxh2#:

A1:
2. Qxe1 Rxf2
3. Qg1 Qf3+!
4. Qg2 Qxg2#
A2:
3. Qxf2 Rxf2
4. any Qg2#/Qxh2#
B:
2. Be4 Rxf2
3. any Qg2#/Qxh2#
C:
2. Bf5 Rxf5
3. Nf4 Rxf4
4. Qf3 Rxf3
5. Rxe1 Rxf2
6. any Qg2#/Qxh2#
D:
2. Bf1 Qxf1+
3. Rxf1 Rxf1#

Hi Susan Polgar,

Well,others had already suggested the best move for Black - "Ne1"

so nothing to add further.
