No, you're not stupid. It's not extremely intiutive, and not well documented.
(1) Go to the "Conditional moves" and "Deep mode".
(2) Do his move, click "Record conditional move".
(3) Do your own move, click "Submit Conditional Move".
There, now you have registered a conditional move.
From there, from that position, do (2) and (3) again, and you did the next conditional move. This is called cascading conditional moves.
If you just want to do one conditional move, then the Quick Mode is enough.
Is this what you wanted to do?
