Well, West could simply not fathom that you opened 1NT with this shape. I'm not sure I would blame them all that much, actually. I do confess I don't see the benefit of leading the T over the 5, or why East is ducking. Also East should have somehow informed West of their amazing heart holding (which should be impossible based on the play to trick 1?), so West can freely pitch hearts and come down to T864 A in the 5-card ending. Then you can throw West in (spade ace, king, club) for 'only' 12 tricks, or more reasonably just take your top 11 tricks.


I know right! - I open on my HCP - it seems to pay dividends - although I get a few weird hands. I've started to draw the line at hands with voids.

In a death-defying display of defensive devilry, the East robot cunningly and contemptuously ignores convention and gives me a convincing lesson in card-play.
Watch the trapeze act in in the end. I advise sun-block.

This is from a matchpoints Tournament - not a minefield I really like to enter, so I tried bidding "normally".
Here's the hand.

In an astonishing and action-packed array of artistry, the androids avoid annoying me again.
The ending is a real joy to watch.
Don't try this without medical supervision.

Yup, robots not much worse than declarer.

What should OP have done ?

You start with 4 spades one heart, one diamond and 2 clubs providing you can get to dummy to take the diamond.

So, win the spade in hand, cash a club and lead a diamond while you still have a spade entry to dummy, as it happens with Q dropping and W unlikely to fly A, you can now run the 9 and make 10 tricks trivially.

The rule of restricted choice says that once the A has fetched the Q, since he might equally have played the J from QJ the queen is more likely to be single than from QJ.

It looked initially as if you were going for the double finesse in clubs, but when you got to dummy a second time you tried to drop the jack. Surely it is better odds to play for split honors based on the principle of restricted choice and play to the ten?

Once you used your spade jack at trick one, the only clean entry to dummy, the robot could theoretically have gone up with the diamond ace and cut you off from dummy and the diamond winners. You are then probably going down.

Yes but the robot thinks you have a 2N opener so thinks you have 2 diamonds

You are all absolutely right - I'm totally ashamed of myself. This one was particularly egregious on both sides.

Hence why I said theoretically. I'd be surprised if any robot or human would put their ace on thin air when it is right because declarer has an off-shape 2NT opening.

AND NOW. just when you think you've seen everything I avoid death in a defensive debacle that defies description.

Here it is.
East opens a sensible 1 I optimistically upgrade my meagre 14HCP 4333 to GKW and bid 1NT. West wisely doubles for penalties.

There's an angel on my shoulder, or as they say in East Germany ein Jahresenedenfigurenmitflugeln: religious symbolism being illegal before the fall of the Berlin wall.

Recently, I was told NOT to return my opponents lead because they might be trying to set up a suit.
Thank you robots... for 100%

Again they probably assumed you had your bid, rather than opening a 15-17 NT on 13

He had 14 HCP, but this all reminds me of one or two notorious pairs at my bridge club who are very difficult to defend against, because they bid so wildly, it is almost like playing against a pair that psyches every third bid (or playing against beginners who have only learned a fraction of the system and are guessing the rest). Occasionally it all goes in their favour and they come top.

AQ KJ K looks like 13 to me, but yes (as somebody in my much younger days who did psyche a lot with usually good results) it can cause massive problems for the defence.

Sorry you are right, I was looking at the deal where he stated he upgraded his 14 count (AAKQJ) which was the previous link. If you are playing a strong NT I don't understand what is wrong with opening 1. NS might get to play in 2 or East might venture a TOX, and EW play in 2 or try for +200 by defending 2X. It will likely go down with the unfavourable lie of the cards.

If West has T and J left, it's the right play.

When you lead the J, it was likely you had the A.
Later, as far as West was concerned, you were "known" to have Q hence West's plays did not make a difference.

The key to understanding GIB is that it's play is extremely logical; it's just completely unable to draw any inferences from your play, assume you will be play double-dummy, it essentially can't signal, and it will rigidly stick to its assumptions about your hand from the bidding. Just think of GIB as kind of, uhm, robotic...

Once you realise that, you'll find more ways to exploit that. E.g. often when you can pick up a suit on a guess, GIB will just discards enough cards in the suit to remove the guess for you. Other times you can make GIB give you the guess because why shouldn't it.

Simple example - I had a trump suit of AK8xx in hand opposite QTx in dummy, with length more likely (but not certain) on my right but no dummy entry. Lead in dummy. What to do? Lead the T because RHO has no reason not to cover from J9xx - and indeed he did.

I think the North robot might have just shown me how to make a pseudo- squeeze in order to garner an extra trick.

Some people wonder why it's hard to win in the matchpoint daylongs. Here's what happened to me and 27 other suckers and losers for 57.58%.
And here's what someone who believes in the power of prayer, luck, hope, faith, sunlight and bleach did for 100%.
