Why do not the robots bid exactly the same way in the same environment.Discripancies are sometimes quite astonishing. In exactly the same bidding environment 3 to 4 different sequences can sometimes be noted. Take this hand for instance: NORTH GIB ♠V9xx ♥D7x ♦10x ♣KQ10X SOUTH GIB DEALER ALL VUL. ♠AQ109x ♥AK109x ♦x ♣xx At my table and 4 others the bidding went undisturbed: 1♠ 2♠; 2NT 4♠ At 2 other tables at least, also undisturbed, : 1♠ 2♠ all pass At other tables opps made it difficult for Gib who didn't deem his hand Worth a go so he passed as opps would play 3♦. The obvious question is why not the same action at tables where opps remained silent. These différences in Gib's reactions are not very bot-like and the reasons why this may happen should be made clear: is Gib sensitive to opponents level, for example, or does its play dépend on computer performance.
