Drop if and place the auxiliary before the subject to form an inverted conditional, as in had I known about the merger earlier, I would have sold my shares, or were I in charge of this department, I would restructure the team. Should plus the base verb replaces if for an open or possible condition. These forms create a more formal register.

| Should + subject + base verb | open/possible condition | Should the client cancel the order, please notify the warehouse at once. |
Remember: Had + subject + past participle; Were + subject (+ to); Should + subject + base verb — all replace if in formal register.
