msterkowiec: I think there are two important things worth noticing:
a) dual is easily avoided by adding black pawn f7; in such case main variant looks like this: 1. Bg4 Qh6 2. Bh5 Qe6 3. B:f7 h3 4. Bg8 Qh6 5. Bh7 Qe6 6. Bf5 Qh6 7. Bg6
b) both in original position as well as in the updated position with b.p.f7 3...Qe6-h6 is not a good defence due to 4.Bf7-g6! (leads to short mate) (2021-07-02)
