I admit I'm not familiar with the term "Shape-Shifter Squeeze". Is it known by any other name, Nigel?

I coined the term because shape-shifter is descriptive of the theme
in common variety of squeeze-strip.
On the left is a basic example.
You, South, declare 6N
On a red-suit lead, you cash all your ♠s.
You must guess in which red suit, West has kept fewer cards..
You cash the tops in that red-suit to force West to discard the other red-suit.
Now that West has a suitable shape, you strip the remaining red-suit.
Finally, you end-play West in ♣s.

This is interesting, Nigel. The second example is a strip squeeze as you have two losers. On the original board you have only one loser, so even though it is a variation of a strip squeeze, it isn't (to me) technically a strip squeeze. Have you 'invented' a new type of squeeze - even though it is probably quite common - with the "Shape-Shifter"?

Would welcome additional comments from squeeze experts here: I don't count myself as knowledgeable about this subject matter than other more experienced players.

IMO, they are both strip-squeezes -- but of a particular kind -- where you need to reduce an opponent's hand to a particular shape.
For example, if cash tops in the wrong red suit, in the second example, then West can keep ♣KQ doubleton and a red winner

My replies to this BridgeWinners thread contain more examples of shape-shifting squeezes.
Somebody else called it a Rosenberg squeeze
but Debbie Rosenberg uses that term for a Similar but slightly different squeeze in the OP of this BridgeWinner's thread

Hey, Nige,

It is an interesting position but it is the ability to ruff out the exit card that makes the position work, so to my way of thinking it is more in line with other trump squeezes, a combination of trump squeeze with strip and endplay, so perhaps a strump squeeze?
