Sorry, this user has no cards yet.
What shows 3♣︎?
Prepared club. Could be 2 cards, maybe only if 4-4-3-2, maybe also other forms of (443)-2 or 3-3-5-2 or 3-3-4-3.

I've seen examples where people play the same approach (cheaper of fourth suit / 2NT artificial GF, most other calls weak) after 1m - 1M - 2R (reverse) too. That also seems eminently sensible ...
