9.1 If the striker hits the ball which, before reaching the front wall, hits the opponent (including anything worn or carried), play shall cease. The Referee, in addition to considering possible infringement of Rule 17 shall assess the ball’s trajectory and shall:
9.1.1 award a stroke to the striker if the return would have been good and the ball would have struck the front wall without first touching any other wall, unless Rule 9.1.2 or 9.1.3 applies; (G4 & G5)
I fear that the rule book agrees with you... Official US Squash rules state that:
Shoot.
