The white rook is pinned to the e1 square by the back rank mate threat of Qe1. My first look at the position led me to want to play Qc3 to deflect the white queen from the other back-rank mate threat of Rd1, but the white bishop has d1 under observation. How does one take all of this and unravel the white defense? Here is how
1. …..Nd1!
Attacks the pinned rook, and now white has only bad options to continue. Taking each in order:
2. Bd1 Qc3! wins the exchange as white cannot take at c3 since the bishop is now on d1 rather than guarding it- the point of Nd1 in the first place. Or
2. Qd3 Qc3! 3. Qf7 Kh8 winning a full rook since the black king is protected from harrassment by the queen now on the a1/h8 diagonal, and white still has king problems of his own. Or
2. Bf7 Kh8 3. h3 Qc3 again winning a full rook. And,
2. Re3 Ne3 wins a full rook, too, since the knight can’t be recaptured due to the threat of Qe1#.
The other knight attack on the rook does not work since it allows the rook to escape to e3:
1. …..Na4? 2. Re3 and the position looks ok for white since his king will soon be well fortressed and black’s is looking a little loose due to the attack on f7.
If white moves the rook there is a last rank mate threat (Qe1++); except if the rook moves to e3, which the Knight now controls.
If white takes the knight with the Bishop, the black queen takes the white rook. White can’t take the queen cause of the last rank mate threat (Rxd1++)
So in any case, Nd1 seems to be winning at least a piece.
Well,as usual brainy minds of this blog had already stolen the show( discussed the best moves for this puzzle)- Black’s initial move “Nd1” – nothing much to add further.
1….Nd1 wins an exchange (the R can’t move because of 2…Qe1#) after 2. B:e1 Q:c3
1…Nd1 if the rook moves then 2…Qe1 mate! if 2.Bxd1 then 2…Qxc3 3.Qxc3 Rxd1+ 4.Qe1 Rxe1 mate!
…..Nd1
Bxd1 Qxc3
and of course if Qxd3 then Qxe1 mate

Greetings from Spain
Nd1 !
how about Nd1 threatening the white rook ?
If white moves the rook there is a last rank mate threat (Qe1++); except if the rook moves to e3, which the Knight now controls.
If white takes the knight with the Bishop, the black queen takes the white rook. White can’t take the queen cause of the last rank mate threat (Rxd1++)
So in any case, Nd1 seems to be winning at least a piece.
1… Nd1
(A) 2. R (any except for e3) Qe1#
or
(B) 2. Bxd1 Qxc3 and if
3. Qxc3 Rxd1+ and mate next
otherwise Black is an exchange up.
nd1
1. … Nd1
Nd1 looks strong, with Bxd1 followed by Qxc3. Phil
1. … Nd1 (rook can’t move)
2.Bxd1 Qxc3!
Hi Susan Polgar,
