Three Notrump or Double?

At IMPs, East opens 3 
in third seat at favorable vulnerability. You hold:
| West Pass | North Pass | East 3
| South ? | K Q A J 10 9 A J 9 6 2 A K |
Would you overcall 3 NT (Option A) or double (Option B)? Either option has risks. If you bid 3 NT, a spade lead could be deadly when East holds up his ace to keep communication. If you double (takeout) and partner bids 4 , you will presumably continue with 4 , but therein lies no comfort beyond 3 NT on what could be a misfit. I would double because it’s more flexible, and the danger in bidding 3 NT seems too likely. Nonetheless, my decisions are hardly gospel, so I’ll throw it to Madame Zoltar for a simulation.
Comparison is not straightforward, as double will lead to different contracts depending on partner’s hand. More specifically, North might be declarer in 3 NT, 4 , 5 or 5 ; South might be declarer in 4 or 5 ; and East might be left to play 3 ×. To avoid further complication, slam possibilities will be ignored, as will the remote chance of West raising to 4 .
For a simulation I created 10,000 random deals with the South hand fixed. West and North: unable to open the bidding (including weak bids). East: 6+ spades; 10 HCP max; 5 to 6.5 playing tricks with at least 3.5 in spades; not 6-3-2-2 or 6-3-3-1 with 5-10 HCP (else 2 is normal).
Results are shown below. Trick Average shows the average number of tricks won by declarer (North or South), Make Percent how often the N-S contract is made (including with overtrick), and Overtrick Percent how often an overtrick is made. (The first table excludes cases where East plays 3 ×.) The second table compares the options according to bridge scoring (all results included) with the better option leftmost. Net W-L (matchpoints or board-a-match verdict) counts +1 for a win and -1 for a loss. Net Score and Net IMPs are calculated twice, first with N-S nonvul (green) then with N-S vul (red). Plus values show the net gain over 10,000 deals.
As anticipated, double is the winner, gaining 13,514 IMPs (1.3514 per deal average) in the applicable category. Curiously, it’s a different story at Won-Lost with 3 NT gaining the edge, obviously because of many small pickups (e.g., 630 vs. 620).
In practice I think double would fare even better for two reasons: (1) Double-dummy play seems to favor the 3 NT bid, e.g., give partner K-10-x-x (opp. your A-J-9-6-2) and it’s a 100-percent make, while in actual play a misguess could put you down three. (2) If there happens to be a slam, double is more apt to get you there than 3 NT.
| Option | Trick Average | Make Percent | Overtrick Percent |
|---|---|---|---|
| A. 3 NT S | 9.8018 | 74.17 | 58.08 |
| B. Double | 10.8331 | 79.86 | 51.16 |
| Comparison | Net W-L | NV Net Score | NV Net IMPs | Vul Net Score | Vul Net IMPs |
|---|---|---|---|---|---|
| B. Double vs. A. 3 NT S | -518 | +494,110 | +10,725 | +770,360 | +13,514 |
Actual DealsBelow are 100 of the 10,000 deals, including the first 20, last 20, and 60 in-between with the greatest IMP gains (30 for each option). Numbers after each contract show the tricks won by declarer with double-dummy play all-around.
