Very interesting! If partner's 1NT bid happens to include 3 Aces and one King you can count 13 tricks!
So you bid 4♣, definitely Gerber following the 1NT opening.
Partner answers 4. What do you say next?

You almost refuse to believe it! How can partner have a 1NT opener with only 1 Ace? But you trust your partner so you bid 4NT. Everybody passes and you stare in amazement at partner's 16 points.

Wouldn't it have been funny if partner had thought your 4♣ bid was Stayman? And so his 4 bid would have been showing a suit. And then your 4NT bid would have been Blackwood. And then he would have answered 5 and you would have passed and made it!
