Hello! The robot used a negative double, but did not accept the second suit. It went back to my opening bid with two card support. It left me puzzled as to why it did this. If it is not going to accept the suit of the negative double, what is the point of using the negative double bid? What am I missing? Is this just a robot thing, or is it something I should incorporate into my F2F play? Best regards.

Well its taking a shot at game given the double fit with a doubleton spade honor.
But it shouldnt be, It's a passed hand worth an invite not a game force.
Game fails as you get pumped in hearts.
So need either 3-3 spades or a heart stopper, prefereably the ace
Even then needs club finesse
ill advised

I've noticed similar behavior on different hands. I'd be fine with it if the hand contained short ♥, but doing this on ♥ XXX is ridiculous IMHO.

I think the Negative Double with 3-5 was a poor choice, it was lucky partner preferred clubs.
But I don't think the shot at game in spades was so bad, maybe someone can simulate.

Using a simple simulation, 4♠ was surprisingly good at around 55% (about the same as 5♣). Another question is why isn't North's hand good enough to open 1♣ but good enough to jump to game opposite a minimum opener.
