1 wh. and 2 bl. captures by Ps. bBa1 is a promotee. Both Ks in check so that we must add one man on c2 and one on b6. Can't add a bPb6 (the bNa8 could not be extracted). Can't add a wPc2 (not enough caps. for a promoted bBd1). Only possibility is +wNc2 & +bBb6. Then retract -1. Ba4xNb5+ f7xRe6 -2. Re5-e6 Na3-b5 -3. Rb5-e5+ Nb1-a3 -4. f3-f4 Na3-b1 -5. Ne3-c2 Nc2-a3+ -6. Nd5-e3 Bf2-b6 -7. Nb6-d5+ Bh4-f2 -8. f2-f3 Be7xPh4 -9. h3-h4 Bf8-e7 -10. h2-h3 e7xNd6 and everything unlocks.

But the problem is cooked (as found by T. le Gleuher). Add +bBb6 & +bNc2. Retract -1. Ba4xRb5+ g6xNh5 -2. Nf6-h5 f7xNe6 -3. Nd5-f6 Bd4-b6 -4. Nb6-d5+ Bd4-f6 -5. Nc5-e6 ~ -6. Ne4-c5 ~ -7. Nd2-e4 Be7-f6 -8. Nb1-d2 Bf8-e7 -9. Na3-b1 Rh5-b5 -10. Nb5-a3+ e7xR/Qd6 R/Qd4-d6. The promoted wR/Q is from h8.
