Try: 1. Kc3xPb4?? requires too many bP captures. If white could play
Kc2x?d3, he could force the b-pawn to b5 and mate by retracting Ne7
for Bb4, but an Nd3 stops the mate and Rd3 stops wK from reaching c3.
Therefore, he first retracts -1. Ke1xQf2! Qg2-f2! -2. Ke1xQf2! (not
Ke1xQf1?? allowing ... Qc1 as a defense at the end) Bd8-g5 -3. Kc2xQd3!
b4-b3 -4. Kc3-c2 b5-b4 -5. Ne7-g8 and 1. Bb4#. Uncapture of 3bQ.
