Using jump with Queen is part of the issue.
She will only use a jump if she would have shot that wall otherwise. Her targeting algorithm still sees the walls as obstacles, even though her moving algorithm knows she can jump them.
If there is anything she would go for in preference to shooting that wall, then she will still go for that when there is a jump spell in force.
4 EQ is much more effective in persuading the queen to go through what started as walls.
