I'm looking for a basic Kaplan Inversion write-up.
I've googled It and the only write-ups I found involved Gazilli and transfers.
I'm looking for it in a Precision context, so Gazilli is a bit of an overkill. It is understandable why people using 2/1 would throw Gazilli in there.

For those who don't know the Kaplan Inversion or Kaplan Interchange in it's simplest form involves switch the 1♠ and 1NT responses to 1♥. The main goal is to handle Flannery hands (intermediate hands with 5 hearts and 4 spades).
So 1♥-1♠ is artificial showing 0-4 spades and acts like a forcing 1NT.
And 1♥-1NT shows 5+ spades and is forcing for 1 round.
Usually 1♥-1♠-1NT is used to show hands with 4 spades.

I am looking for something that is mostly natural as a simple way to show Flannery hands without using up 2♦ bid.
Need bidding after 1♥-1♠ and 1♥-1NT.

If anyone can post a link to or a write-up on basic Kaplan Inversion it would be appreciated.
