After 2♠-pass-? a player tanks (and passes) with Kx-Axx-Qxxxx-xxx and NS don't bid anymore (being cold for a heart game).

W opened 2♠ 8-11
N had: xxxx-KJxxx-x-AKT
E had: Kx-Axx-Qxxxx-xxx
S had: A-Qxxx-KJTx-QJxx

Some people say that the contract should be adjusted to 4♥.

But, let's suppose a little modification, N/E exchanging two clubs/spades - so the hands now are:

W: same
N: xx-KJxxx-x-AKxxx (borderline pass)
E: Kxxx-Axx-Qxxxx-x (a genuine hand with support)
S: same

East now probably has a clear bridge reason to think about (what is the best line in given circumstances:
a. bid 3♠,
b. bid 4♠,
c. bid a tactical 2NT, or
d. bid a non-standard tactical pass intending to revive the auction if opponents do balance)?

The question is - do you still adjust?

(I hope you see what I'm suggesting.)

I would not consider 2NT to be "tactical" on that hand, since there are plenty of possible hands for opener on which game is excellent (indeed, it is on a finesse with the hand he actually holds).
