1. ... Nb4

Discovers attack on the unprotected queen and threatens Na2#. White cannot defend against both threats.

If
2. Qa3 Nd3+

If
2. Qb3 Nd3+
3. Kb1 Nc5+

If
2. Qa5 b6

White has to give up queen in exchange for knight to prevent mate.

Since the white king cannot move Black can simply win the queen by threatening a smothered mate:
1. ... Nb4!
2. Qb3

2. Qxd7 Nxa2#

2. Qxb4 Bxb4
3. cxb4 Qc6+ winning one piece back.

2. ... Nd3+
3. Kb1 Nc5+
4. Ka1 Nxb3+ +-
