Partner and I play transfer after 1 Major open and opponent takeout.

Our XX shows a balanced hand with 6+ points, no 5-card suit, and denies support to the open Major.

The transfer starts from 1NT (clubs).

In a club game, against a grand life master, she thinks this XX is different from the usual practice thus is alertable.

She suggested us to confirm if this XX needs to be alerted or not.

My partner and I will always alert from now on, but I would like to know your opinion if this is alertable or not.

Thanks ahead.
