[Manastorm]

I noticed something as a declarer, which seems to fool GIB. Sometimes there is a dangerous switch, which you don't want to see. One way to tackle it, is to make GIB decide early what to do. The simulation GIB does has a greater error, when there are more cards left. However you can improve the situation by playing certain cards. If you have AKxx in a suit, you should take the ace early. The effect is that GIB is more inclined to lead that suit now, since its simulation sometimes suggests it is the winning action to cash out KQ in the suit. You wouldn't bare the suit like that would you, but GIB doesn't know it. If you don't cash the ace, the simulation may consider opening the suit very dangerous and by doing so increases the chance of an unwanted switch.
