It turned out that the majority bid and made 3NT, and 4♣ was indeed hopeless. I lost 10.2 IMPs here.
How could I know that 3NT would be safe? Or should I bid it anyway whenever holding 4333 as a dummy?
#1 you have no idea, that 3NT would be safe
#2 4333 shape is not an asset, it is even a reason to downgrade
#3 missing a makeble 3NT on a 24 count is not the end of the world, someone in the thread said, 3NT could
be defeated, but defence is hard
Having said that:
Bidding 4C is a stupid call, as it is , partner is dead min for his call, but could be a bit stronger,
3NT may be cold, but the law of bridge dont allow reaching 3NT after someone bid 4C.
A reason peoble like to open NT as much is possible, their agreement sets after a 1NT opening are usually
better than after a suit opening, and agreement sets after minor suit openings are most likely worse than
after major suit opening.
this is one major reason, why lots of peoble like upgrade into NT openings, but rarely
downgrade out of an NT opening.
Add to this, NT openings make it harder for the opponents to enter the bidding.
