My Self-composed Study (in fact the only one which has been published^^)

Wanna try? White wins.

Final version: 15th December 2019

Qe7+ Kc5 Qxa5 Bxa5 Kxa7 and white wins with promoting the a pawn?

Quite a lot of illegal moves (or missing ones)...

Oh I meant

Qe7+ Kc3 Qe1+.

If Ka3 then Qxa5 Bxa5 Kxa7

If Kd4 or Kd2, then the same line, trading queens to remove the bishop defender, taking the a pawn, and promoting.

Apologies for the poor notation.

Not quite.

Let me resolve the mystery, however it ain’t easy.

Oh I didn’t realise the queen could block Qe1+

Good puzzle

Thx. It remained the only self-composed study (plus some mate problems).
