|  Which Suit To Lead?

by Richard Pavlicek |
As West, your opponents quickly reach 3 NT on this auction:

West
Pass | North
3 NT | East
All Pass | South 2 NT1 |
What is your opening lead?
Reasonable choices are the
2,
10,
5 and
8. My intuition would be a heart at IMPs, and the 10 seems preferable to low (to unblock) in case partner has five. Matchpoints (is that bridge?) is another story, and it feels like a coin flip between a spade and a diamond. I doubt anyone could give a definitive answer, so lets see what a simulation has to say.
To set up the simulation I created 10,000 random deals with the West hand fixed, and the other hands constrained to fit the bidding. South: 20-21 HCP; balanced (may have 5-card major). North: 5-10 HCP; no 5+ major; no 4+ major unless 4-3-3-3; max 11 total points; freakness less than 6. East: Playing tricks less than 7.5 or freakness less than 6, i.e., East would need 7.5+ playing tricks and extreme shape to bid over 3 NT.
My intuition was right. The
10 wins comfortably at IMPs, with the other choices closely bunched. At matchpoints the
2 wins narrowly over the
8. Most notable of all is the proximity of the choices. The results may be the closest of all my simulations, but Im too lazy to check.

Trick Avg shows the average number of tricks won by declarer. Make Pct shows the percent of time the contract is made. Matchpoints shows the raw total (European style: 2 for a win, 1 for a tie) and effective scoring percent. Total Points and IMPs are shown similarly as raw totals and percents, with separate accountings for N-S nonvulnerable and N-S vulnerable. (Vulnerability does not affect matchpoints.) All numbers are relative to declarer, so lower values are better for the defense.
Below are 100 of the 10,000 deals, including the first 10 and last 10, and selected deals in-between where the lead made a significant difference. The number of tricks won by declarer is shown for each lead, assuming double-dummy play by both sides thereafter.
