Caissa defends all wrong and allows mate in 2 instead of mate in 3. Don't know what's the problem. Perhaps I should add paths?

Here is a wrong defense that leads to mate in 2:
1.Qxf4+ Kd3 2.Qe3#
1.Qxf4+ Kd3 2.Bxb5#

Her answer to 1.Qxf4+ should be ...exf4. With that mate in 2 pattern is stopped.

Thanks in advance!
