An Honourable Push

Both sides performed well on the final deal of the fourth session in the Bermuda Bowl Final:
If 4NT was keycard for hearts South’s 5 was consistent with one keycard. West’s double was enough for North to prefer 6NT, which was unbeatable, +990.
4 might have been a transfer to RKCB and the subsequent bidding seems to suggest that is the case. When West doubled 6 North found the essential conversion to 6NT to flatten the board.
