We need a break from encrypted signals arguments, so let's go back to an old standby, the boundary between careless and irrational.

Dealer West, both sides vul, IMPs (if that matters to you.)

Bidding: 2NT, 3D transfer, 3H, 4H.

1: CT,4,6,J
2: S4,7,Q,2
3: H2,3,J,K
4: C3,5,Q,A
5: H6,D2,H4,HT
6: D6,DA

At this point declarer claims 6 of the remaining 7 tricks.
NS look at him expectantly and he says "all tops" or something like that.
I don't think anyone believes West has miscounted the trumps -- but he has not shown any awareness of the fact that he has several different ways of entering dummy, which are not guaranteed to be successful.

Do you allow him to make, or do you impose entering dummy with CK, ruffed?
