World Championship final. Your opponents are Lauria - Versace.
Your partner Eric Rodwell.

♠J98 ♥J643 ♦K43 ♣KJ2

We are vul. RHO deals and bidding goes:

1♥ - pass - 2♥ - pass
2♠ - pass - 4♥ - pass

2♠ is natural; invite+ 1♥ is 11-22 natural.
Your lead ?

(I am posting this because Meck led something different than I would have and my very simplistic simulations confirmed he was right, still it's kinda surprising to me).

I guess the ♣2.

♣2 certainly seems like the right lead. Most likely to produce something useful, and least likely to give up a trick that matters.

seems like the 2♣ looks like it requires the least from partner to be a winner.

I would choose the ♣2 but I am very interested in your simulation and Meck's choice.

[bluecalm]

No more takers ?
Meck led 8♠.

My choices were ♣>♦>♥>♠
I thought we need to attack after this auction hoping to force declarer.
I also wouldn't be surprised if ♥ scores high double dummy as I learnt that leading from xxxx of trump in similr situations is usually very effective. Here we have Jxxx but double dummy it doesn't make that much of a difference (thus I think this lead is overrated in simuls).

I tried many constraints for Lauria's hand (14-19hcp 5-4, 13-16 5-4 or 12-14 6-4, etc etc.) and for Versace's I tried 8-9 with doubleton somewhere or 7-8 with 4card support etc. but ♠ always came first with♥/♣ being 2nd choice.

Full hand from 2003 bb final:

Scoring: IMP

On actual layout probably every lead would have worked so it's not that interesting (♦ would allow to make it double dummy but not in actual play I believe)

[billw55]

So, why is the spade best? Just least likely to give something away, with ops not showing a threatening side suit? Or is there more to it?

Double dummy simulations always favor passive leads. They are very unsuitable for lead decisions.

Having said that, I did a simulation and the following leads set 4H most often:

54 times: ♣2
51 times: ♣J
50 times: ♥3, 4
49 times: ♣K, ♦3, 4, ♥6
48 times: ♠8. 9

In my simulation RHO had 15-16 HCP with exactly 4 spades and 5 hearts. LHO had either 6-9 HCP with 4 hearts or 7-10 HCP with 3 hearts, also at most 3 spades and no shortness.

Interesting. Your result suggests (a) that a spade isn't really best, and (b.) there isn't much difference on any lead.

bluecalm? Can you be more specific about your sim results?
