Lia Bidding

 

IntoBridge uses a programmed approach to the bidding, they say. The alternatives would be Neural Networks or randomized Monte-Carlo, or both combined. This AI method is trained with thousands of hands and learns good bids. If it gets stuck, it generates random hands around the table with the current knowledge, collecting the results with a double dummy analysis. IntoBridge does not do this as far as I know.

However, I find the bidding of Lia often strange. The explanation of 3♣ is 16-18 points with a good 6-card suit. North must not pass with his hand. Yet he does. We have enough points for game, but no fit. So, North should show his stopper in ♥. That suggests 3NT with a diamond stopper.

3NT is by no means bullet proof. As the cards stand, it cannot be beaten. I estimate the chances to make it as 50-50, but only with best defense. With my Bridge Replay program, you can study such hands by shuffling the cards of E/W and analyzing the results in double dummy fashion.

Some players opened 3♣ with this hand. This is probably the right hand for such a bet. It shows a safe 7-card suit with some side values, but no ace. Lia on North bid 3NT after this. One player opened 1NT which got him to 3NT too.

It is interesting to study the contract of 4♠. I think you can make it only because the ♠10 drops.

This is a nice one. You reach 4 ♥ , and West starts with the ♠8. If the trump finesse fails, you count 10 likely tricks, including one ruff of a spade at the table. But then there is also the chance to cash the ♣K for an overtrick. Easy. You are glad to combine all these options, and start a simple plan.  Cash the lead and make the finesse in hearts which fails. Another spade comes from West. When you notice that you are going to lose two trump tricks, you collect your tricks, ruffing one spade at the table at the end, and set all hopes to the club finesse which fails. One down. Everybody played like that, including me. You certainly spotted the way to make the contract? Of course. You could leave West with two trumps and throw him in after you trumped your space and cashed your  ♦ Q. Is this difficult to see at the table. Maybe. But you will definitely see West's 4 spades and hearts. When he discards the  ♦ J on  ♦ Q, the coup is very likely to work.

2NT are not makeable, but if you go down only once, you are good against 2♠ by opponents. 2 ♥  would be a nice contract and just make with good play, but opponents won't let you play that easily nowadays, not even the robot Lia. The lead was ♠5, East following with the ♠Q and won in the hand. Due to severe communication issues this hand cries for a try to let the opponents play into the finesses. So, I correctly played the  ♥ A followed by a small one won by West, who cashed  ♥ K too, the followed with the ♠10  because everything else helps the declarer even more. At that point, I went for the clubs, but the diamonds actually work, playing for one honor doubleton at East. Check it out.

This bidding got me stranded in 2♠ because of Acol. That's actually not bad. You cannot make it against good leads. But neither can you make 1NT, the contract you might reach by downgrading the hand to a weak 1NT. On almost all other tables, the bidding started with a strong 1NT and continued to a good heart contract for E/W by the bidding below. In that case, the "blocking" value of 1NT fails, and the direct mentioning of a spade suit works out to be superior.   But I spoiled that advantage by going down twice. Actually, I could have made the contract after the lead of ♣K. It is always tough to play 1 4-3 fit, and this is no exception. I started with a heart won by East who followed with a trump to prevent ruffs. I now can ruff only one heart at the table. The best line of play is to drive out the ♣Q now. If West takes it on the first round and returns a trump, you can play clubs to dummy and continue it. If he ducks one round, you need to find the finesse in diamonds t...
