Ace Skier Posted February 15, 2012 Report Share Posted February 15, 2012 Why why of why can the robots not pull the trumps first. I have lost so many games because of this too many too even mention. Even a bad human player will normally pull the trumps. Quote Link to comment Share on other sites More sharing options...

georgi Posted February 15, 2012 Report Share Posted February 15, 2012 Pulling trumps is part of the plan of play i think. Considering let's pull trumps first might be already the first step to make contract down definitely. Every suit contract might have specific need of which plan to pick like extending trumps by ruffing with short trump hand, cross-ruff, reverse dummy, endplay the winning trump, etc etc etc. For a particular hand GIB might or certainly went wrong if picked unsuccessful plan and being ruffed/overruffed in suit where it held 4-2 and opps 6-1, took unneeded finesse for +1 putting the contract in jeopardy, which every kibitzer would avoid. Pulling trumps as default strategy sounds like if GIB is declarer of NT and first task to do is to pull all available top honors tricks. If then is capable to make the contract - good, if not - well, next time better. Clicking GIB button on hand diagram which shows any lead makes contract = or +1 and then declarer (GIB) went down is not alert for bug in GIB software. GIB button activates the Double Dummy computation of the hand layout, and GIB declarer is allowed to simulate and imagine the opps hands layout, but not to "peek" at them. So depend on the point of view it's the worst declarer as making cold contract down while its human partner would make even +1, next time is the opposite.

barmar Posted February 16, 2012 Report Share Posted February 16, 2012 I don't think he's talking about hands where it needs to use the trumps for ruffing before it can draw them, that's beginner bridge. But there are lots of hands where GIB starts drawing trumps, crosses over in a side suit, then finishes drawing trumps. I don't think there's any "strategy" here, it just doesn't think it makes a difference. None of the hands it dealt in the simulations had an opponent short in the suit so that they could trump that side suit play. GIB doesn't know about safety plays and 100% plays, it just does simulations. And if two lines of play are equivalent in the simulations, it has no reason to prefer one over the other. It doesn't have any kind of strategy, it doesn't go by rules. Quote Link to comment Share on other sites More sharing options...
