How come GIB's system includes weak 2's in 4th chair?

[Quantumcat]

Quite often GIB comes up with things that were obviously hard-coded in by someone who isn't too good at bridge. For instance sometimes you bid something like 1♦ then rebid 1♠ then 2♠, and the explanation for 2♠ is 5+ diamonds 4+ spades, instead of 6+ diamonds 5+ spades. And GIB acts like he believes this explanation, refusing to play in spades when he has three of them. Weak twos in fourth seat is probably another example. However, it might have been put there on purpose by people who play robot races - when you pass your balanced 14 count, you'll be quite happy when GIB bids 2♥ - he'll probably make it and he stopped the opponents from bidding their spades, so you get to watch GIB play fast for +110 instead of spending 2 minutes trying to defend for +50.

Can someone who plays robot races please explain just how silly that answer is?

Because if the robot has a weak 2 bid in 4th seat, I'd rather it just pass so I can get on to playing a game...

In robot duplicate, i don't see anything wrong when he opens 2D/H/S on the 4th seat because all meet the same bidding.

In robot races, as GIB is dec, he can play very quickly and get +110.

From my experience, on the 4th seat, GIB often opens 2d/h/s with good suit or 9-10 HCP, as i have the best hand, i always raise 4M with 3 cards or even 2 if i have many aces. Another tip is that i find that GIB plays more quickly in a game contract than a part-score contract. Even the game contract goes -3 or -4.

It seems unlikely to me that these things were hard coded in by someone bad at bridge; it's more likely that the people putting in the DB just neglected to put in a special rule to cover these situations, and it falls back to some more general case meaning, and then the bidding and/or description is off in these cases.

Humans process negative inferences well, with computers you have to explicitly tell them practically everything.

When I said it is good that GIB opens 2♥ in 4th seat, I was more thinking of comparing that to him opening 1♥, then the opps bidding 1♠ 2♠
