  Errata ;

  This study has the following references

  Krejcik, tl10#465, 1953

  Nevertheless, it is a sound study.

  1. … Ke6
  2. Qc4+ Qd5
  3. Nc5+ Kd6
  4. Nb7+ Ke6
  5. Nd8+ Kd6
  6. Qb4+ Qc5
  7. Nb7+ Kxc6
  8. Nxc5 Black wouldn’t want to do this, so…

  1. … Kf5
  2. Qf8+ Kxe4
  3. Qxf3+ Kd3
  4. Qd1+ and the queen, which Black doesn’t want either, so…

  2. … Kg4
  3. Qxf3+ Kxh4
  4. Qh1+ Kg4
  5. Qxf3+ with a perpetual, which Black would go for at this point, but White has better…

  5. Qg2 Kf5 (otherwise, Qh3#)
  6. Qh3+ Kxe4
  7. Qf3 Kd3
  8. Qd1+ and the queen.

  Bad day for Black.

  I was careless in my post. The move that led to perpetual should have been 5. Qf3+, not 5. Qxf3+, and the move to avoid the perpetual should have been 5. Kg2, not 5. Qg2. Bad day for jcheyne.
