The opening leads (part 3)

This is the third segment of a series which examines all the opening leads of Wladow-Elinescu in the knockout stages of the Senior championships in Bali. In the first segment, we looked just at the hands of the partner of the opening leader, and asked the question: What suit (if any) would one signal for the opening lead if one could give such a signal. This hands were presented in the article. They were also presented in an online survey. The URL for this is:

http://bridge-hand-player.appspot.com/kit_woolsey_opening_leads_part_1.html

In the second segment, the opening leader's hand is shown but with no information other than the bidding. You are asked to judge what opening lead you would make. The hands were presented in the article. They were also presented in an online survey. The URL for this is:

http://bridge-hand-player.appspot.com/kit_woolsey_opening_leads_part_2.html

If you haven't done so already, I suggest you take these surveys. They are important in order to establish an unbiased estimate of what signal the partner of the opening leader would probably have given if he were giving a signal, and what the likely opening lead would be if there were no UI.

In this third segment you are presented with the same opening lead problems, but this time with the information that partner has signalled his preference. You also have information about whether or not partner is balanced, and if he is distributional what his short suit is. You might or might not choose a different opening lead with this new information. The URL for this survey is:

http://bridge-hand-player.appspot.com/kit_woolsey_opening_leads_part_3.html

This is perhaps the most difficult of the surveys to answer, because (hopefully) we are not used to this type of decision. Don't hold back for fear of the lead being too obvious a suggestion of cheating. Take full advantage of the information, both the signal and the distributional information you have about partner's hand. Of course sometimes you will ignore partner's signal and make the lead you think best on your own hand. Just as with proper signals, a signal is just a suggestion of what the signaler thinks is best, not a command. Other times you will happily lead what is signaled for. This is entirely your judgment, just as it would be the judgment of a player if he were receiving such signals.

In the fourth segment, the results of the surveys will be compiled. The full hands will be shown, along with the opening lead which was chosen at the table.
