Seinfeld9 Posted January 4, 2011 Author Report Share Posted January 4, 2011 Why GIB play ♦ instead of ♣? 3NT should have been made. Quote Link to comment Share on other sites More sharing options...
Bbradley62 Posted January 4, 2011 Report Share Posted January 4, 2011 Suppose the hand was:[hv=pc=n&s=sat5hktdkq4ckqj85&w=sj864ha94d73cat72&n=skq9hq86djt98c943&e=s732hj7532da652c6]399|300[/hv]In this case, clubs do not run, so GIB needs some diamond tricks to make his contract. GIB must knock out ♦A before his ♥Q is gone. Apparently, GIB ran some simulations and determined that he must protect against the club stack in West.

Didn't it simulate how times the ace would ducked? Once is all that is likely. If there is a club stack, you will go down. Quote Link to comment Share on other sites More sharing options...

Doesn't matter how many East ducks. Once he wins he can clear hearts, but cannot get back in to cash to long ones, since clearing hearts takes away West's final heart. I'm not opining as to the probabilities of various situations, just pointing out that there are times when going after diamonds instead of clubs works.

barmar Posted January 5, 2011 Report Share Posted January 5, 2011 Which again comes back to the problem with GIB's simulation-based strategy. It doesn't know how to "test clubs", "combine chances", or make "discovery plays", which are strategies that we routinely teach advancing players.

Since Declarer-GIB presumes that Defender-GIB will defend optimally, if West holds ♣ATxx and East holds ♦A, you cannot test clubs even once, because West wins the first club, and clears ♥, and waits for East to get in. Declarer has only 8 tricks. Quote Link to comment Share on other sites More sharing options...

I can show you 20 hands where the club play is correct. !c is def the correct percentage play. Think GIb is dealing bad samples Quote Link to comment Share on other sites More sharing options...
