I would take it, I think that my partner would not understand if I duck and would ask about it. Then the opponents would realize what had happened, they would not only have avoided a doomed slam by sheer luck but they also made an extra trick by a stupidity of the opponents. I think their moods would improve while the moods of my partner and me would go down fast.


lol you are the best

Sorry, I'm retarded and decided overtricks get scored the same as undertricks.

How is it 2 or 3 imps? You are throwing away some fraction of 1 imp overall (the times that your teammates stay out of slam). Let's call it .4 imps. In return you gain the swing of making them think they will probably lose 13/11 instead of probably winning 13/11. I have no idea if it's worth it and I would probably say it depends on the opps and also on the exact hand (if it is like 33 HCP and a fit, then you're probably throwing away a very small amount since your teammates will almost always be in slam, so it would def be worth it).

I sort of had something vaguely resembling this at the table. Quite a few years ago when I was more obviously a young(ish) random female bridge player, and less obviously the Bridge Goddess that everyone knows I am now* we were an unseeded team in a national KO playing one of the top teams. LHO dealt and the auction started (only us vulnerable)

P 3S P 4S
dbl P P ?

RHO's pass was very slow.
I redoubled 4S which I suspected at the time might have negative EV (it did; it converted +790 into +500). But I thought it was worth it because I wanted to show oppo that they couldn't take liberties; LHO was known for very aggressive protections and he needed to be told that he was 'only' risking a doubled game.

This is what I'd do at the table.

You need a reason to drink?

No I think he was saying that he was drunk, but hadn't been drinking at all--so there was no reason for him to be drunk.

Board 2 of set 1 of the spingold.


Initially I thought it was a good idea to duck the finesse so as to screw with the opponents minds. However, it is only the second board, and I doubt that the opps would panic much. If it were later in the match, it would be very different. I understand that opps may try to swing to regain those 'lost' IMPs but, against decent opps, they will grind it out. Against lesser opps, they'll just jump to 6 xD.

Win it, from the record of spingold or any event at that level the IMP per board is usually less than 1 in average, why wasting 1 IMP(even not for sure) unnecessarily?

This is something I did when I start to learn this game. When I miss slam/game in bidding, I also mess up the declare play to make exactly the contract I bid to make partner feel better. B-)

I'm not playing psychological games, I'm playing bridge.

Any game that requires the use of a brain is psychological. In bridge tons of IMPs/MPs are thrown away because of bad psychology.
