Given a chance …
Big hands, when opponents open, especially at high level, can be problematic to describe, especially since the scare of getting too high is always a concern.
How will you handle this 22 pointer after partner passes and RHO shows a 10-13, 5-5 minors with 2NT?
Say you start with a double (which primarily says penalty interest in one minor) and opps run to 3♦ which you expect. Do you want your double at this stage to be penalty or TO? What do you do if you play penalty doubles? Do you think you have enough to penalize? You can reasonably expect to get 1♦ , 2 major tricks (hopefully) and atleast one ♣ – certainly not enough to justify penalizing. On the other hand, you could be making a major game (give pd something like Axxxx spades). Would you settle for 3N in that case? With a single stopper?
How about an immediate 3N? Again you expect a ♦ lead, and unless partner can produce a 2nd check, that won’t play too well.
Luckily for you, your agreement is doubles are take out. And you are much happier making a take out double.

What now?
If West is 2-1-5-5, it does not matter who has the CK, when he returns a D to the King on the table. You can cross to the SQ, and run the C9. If East has the King, the club winners can be rammed through him as trump substitutes. If the C9 wins, you have 6 winners outside trumps, and they cannot prevent you from ruffing the 4th H on the table with the 10, and score your little trump en passant — after C9 wins, cross to cash H winners, CA, and play C ruff over ruff, ruff H, club again so that their trump and D tricks clash.
