Matchpoints, ACBL robot individual

I guess you're supposed to struggle in the known 4-2 (or possibly 3-2) ♠ fit, because when you try to wriggle off the hook, the robot slams it in deeper. The robot won't let you play a normal 2 ♥ contract, so you have to play 4♥. The 2 4-1 side suit splits with singleton honors offside were the perfect finishing touch to the hand. No wonder there is so much psyching - shorting out the robots is often easier and more successful than trying to bid and play accurately.

No way to look at your hand diagram,maybe you don't know how to create the hand diagram,it is a very simple thing:it only need two step.

First step:

Add " [hv= " into the front of the hand link.

Second step:

Add " ]499|350[/hv] " into the back of the hand link.

Now everything is good.

If you completely disregard the published meanings assigned to the bids by GIB, it is almost forgivable for North to determine that its D:K is worth more than average and decide that he is worth a game try having found the Heart fit. Not that 2S is the particular game try bid that I would have come up with, unless it conventionally showed weakness in the suit.

Continuing on that theme, South should retreat to 3H rather than 3C which sounds like co-operation with the game try. Indeed if we now uncover the blindfold and look at the meanings of the bids, 3C does indeed (purport to) show a maximum hand. In light of that, the leap to 4H by North then becomes understandable.

The problem here seems to be that half of GIB seems to think that it is still scrabbling around for a fit, having apparently only shown 3+ Hearts with the Double. But if it is scrambling for a fit, then it becomes unreasonable for 3C to show max.

Certainly some problems here. Starting with the fact that any move over 2H is a ridiculous over-evaluation. Next, there is no reason that 2S should promise exactly 3 hearts, it should show 5+ Spades and deny 3H, non forcing of course. Then there is the fact that N does have 4 Hearts, despite the description. All in all an abysmal performance by the Robot.

Your description of what the 2♠ bid should show is as negative doubles were originally designed, and the auction would have ended in 2♠. I find that not much in BBO's version of 2/1 is consistent with the original (or even current) approaches. I'm curious as to the source material that was used to develop BBO's implementation, because it is unlike anything I have encountered.
