t is now two years since we launched the chance

to challenge Funbridge's artificial intelligence,

Argine, in a match of five deals. Since then there

have been 5,594,989 challenges! Argine is the outand-out champion

- 4,457,157 wins (80%), 157,898

draws (3%) and 979,934 losses (17%). Only 800

players out of the 95,000 who have challenged the

robot have a positive ratio.

Here is an interesting deal that I played against

Argine:

opt for the manoeuvre that is most likely to succeed

and clearly it is the heart finesse. Once this is

successful, you must focus on spades. If the suit

splits 3-2, there is nothing special to do. But if the

suit splits 4-1, playing the ace to catch a bare honour

is useless because the other player, holding ´KJ92

for instance, will play the two on the ace and will

take the next three tricks. The only interesting case

is when West holds the bare nine. Then you have to

start with the 10, leaving East without any solution

with KQJ2. Either he surrenders a trick that could

be made with the 10 or he covers and will take only

two tricks in the suit.

As usual, to make this

contract, all you need is a good

plan, and to carry it through.

Well done, Argine! This was

East's hand. r

All Pass

The 3NT bid is supposed to promise two spades

in case the opener has six bad spades and an

unbalanced hand. Then he can easily rebid his

six card suit. And that is exactly the case here.

The contract is 4´. The lead is the ™7 (3rd/5th).

How would you play?

Two problems arise: the possible loser in

diamonds and how to deal with the trump suit.

When it comes to the first one, you have the choice

between finessing hearts, finding diamonds with a

favourable 3-3 split or finding the club ace-second

in East. Given the lead, you have no choice but to
