按下滑鼠左鍵掃出答案:
★1. Ne2! Ke1 2. Ng3 ... 3. Qe2#
2. ... Kd1 3. Qb3+ Ke1 4. Qf3 ... 5. Qe2#
2. ... Kf2 3. Ne4+ ... 4. Qg3+ Kf1 5. Qf2#
4. ... Kh1 5. Nf2#
3. ... Ke1 4. Qxd2+ Kf1 5. Qf2#★
A logical miniature. The main plan 1. Qb3+ Ke1 2. Qf3 3. Qe2# still fails to 2.. BxN! Therefore, the wN is transferred to g3 via e2 using tempo: 1. Ne2 Ke1 2. Ng3 and now on 2.. Kd1 the mainplan works. On 2.. Kf2 3. Ne4+ Kg2 (Kg1), Ke1 4. Qg3+, Qxd2+. There is also the set play 1.. Kc1 2. Ne2+ Kb2 3. Nd4 (4. Qb3+) Bc3 4. Qc2+ which cannot be utilized as White has no waiting move and 1. Kxa7? fails to 3.. Be3! pinning the wN so that there is no mate on 4. Qb3+ Ka1! This subtle play was added by Speckmann in the present version of the original Kb5, Qg5, Ne3; Kh5, Bg5, Bb6.
