Would you think this is a practical joke? Neither side vulnerable, you hold:

AK7542
AK
A10
AKQ.

If that isn't enough of a great hand, watch what happens.

LHO passes and your partner puts out the STOP card and bids...2! Yes. SPADES.

That is exactly what happened in the 2017 Team Trials. This was the full deal:

Vul: None Dlr: West	Q109863  J4  K32  98
--  109  J98754  105432		J  Q876532  Q6  J76
	AK7542  AK  A10  AKQ

At most tables, over North's 2 South raised directly to 7. Some started with 2NT and scientifically reached 7NT. At a few tables, North didn't preempt, but East did.

Over East's 3, South doubled. West raised to 4 and North volunteered 4. Now, South jumped directly to 7.

What a once-in-a-lifetime situation for South to have that hand and see those auctions!
