The everlasting battle

The late Gabino Cintra, a World Pairs champion (playing with Marcelo Branco) from Brazil, liked to wax poetical about the everlasting battle between spades and hearts. He was a frequent vugraph commentator from Brazilian and South American events, and he would have enjoyed the following board greatly.
Board 2 from the World Youth Teams Championships finals was yet another skirmish between the two ancient opponents.
Picture
Let’s take a tour through the tables where these cards were on display and see if there is something to be learned from the auctions.Examining the four hands in the quiet environment of our screens, we can see that NS will make 11 tricks in hearts; and that EW have a profitable sacrifice in 5S, paying only 300 in doubled undertricks. But things are never as clear as that when you are looking at only ¼ of the deck, in an important match.

U-26 Open (Singapore vs. Sweden):
Picture
Both tables reached par, through slightly diverging paths. When Singapore held the NS cards, South did not preempt (to the extent that a vulnerable vs. not 4 Hearts bid can be classed as a “preempt”).
West was able to show the overall character of his hand by a jump raise to 3 Spades; armed with that information, East (Mikael Rimstedt) made the right decision to keep on bidding. Bidding five over five is seldom a clear choice, especially when you have two Aces; on the other hand, to compete in high-level auctions with a void in their suit pays off surprisingly often.
When Sweden held the NS cards, South started with the pressure bid of 4 Hearts. This resulted in a hazy auction for all players.
4 Spades by West was much less well defined (ranging from a good hand with 3-card support to a bad hand with lots of trumps). Yu Chen Liu, as East, had a difficult decision when he bid 5 Spades at this table; partner could have had a very unsuitable hand (with more stuff in the red suits). He took the opponent’s red vs. white bidding at face value and everything turned out for the best. North had a clear double at both tables.
​

U-26 Women (China vs. Poland):
Picture
Here, as in the Open U-26, the two Souths started with different decisions, but the end result was not the same. When Poland held the NS cards, the auction was on its way to duplicating the result in the Open, but North declined to double, and so EW escaped for down only 100.
When China held the NS cards, West, at her first turn, cuebid rather than jump raise; assuming a standard meaning for this action, this strikes me as overbidding. North’s cuebid, on the other hand, I can understand: she had a very nice hand, too strong for a mere 4 Hearts. The consequence of West’s optimistic evaluation was that East decided that she had a shot at defeating 5 Hearts, and so she passed, losing 11 imps (650 vs. 100) in the process.
U-21 Open (Israel vs. Sweden):
Picture
When Israel was NS, East started with a (systemically) heavy two-bid, showing 10-13 points. It was a good initial description of his hand; but he did not have any agreement to show a hand that prefers to declare rather than defend (as we call it, a hand with a high offense/defense ratio), and so the partnership ended up stuck with defending 5 Hearts.

I have sympathy with East for not sacrificing unilaterally after describing his hand quite well with the opening bid; but it would have been useful to specify that a double over 4NT meant that high offense/defense hand. (Here, West’s hand was also more vaguely defined than at the tables were the bidding started 1 Spade – 2 Hearts – 3 Spades; banking on the narrow limits of the 2 Spades opening bid, West could have had a variety of hands). At the other table, the preemptive 4 Hearts had a great success when West timidly sold out. A tied board, but some important experiences for the youngsters.

Board 6, from the 3rd segment of the 2018 Junior final between Sweden and Singapore, was very difficult to navigate properly. The traps were dangerous, and they were everywhere. East was the dealer, and EW were vulnerable against not. Let’s look at it from West’s viewpoint:
Picture
A nice looking hand. When Adam Stokka from Sweden held this hand, his partner passed and RHO opened 1 Heart.
What would you do? Most people would probably bid a simple 2 Diamonds, but I think a case can be made (facing a passed partner, and vul vs. non-vul) for the 3 Diamonds overcall.
Would it have made any difference? Perhaps, for this was the full hand:
Picture
After the first bid by West, the bids were all pretty much forced. I would not say that East could never pass 2 Diamonds with that hand, but I can say that I would never do it. And the final result was 500 for Singapore, when EW lost the obvious 6 tricks (2 hearts, 3 diamonds, 1 club), due to the spade blockage which prevented the King of spades from adding any trick to declarer’s total.
After an initial 3 Diamonds overcall, North would not have a natural penalty double.
Would South reopen? He should, but there is no doubt that it is easier for North to double 3 Diamonds than for South to do it.
Meanwhile, in the other room, the Singaporean pair nimbly avoided any trouble in the bidding with these cards:
Picture
There are lots of little things going on in hands like this that explain the big swing. In this auction, the first component is East’s light opening (in a Precision context), even vul vs. non-vul. Many people refrain from light openings because they are, allegedly, risky. But any coin has two sides: sometimes a light opening helps you avoid trouble.

This is not enough to explain EW’s escape, though: full marks must also be given to Jazlene Ong’s restraint with the West cards (and again, the light opening context of Precision helped a lot there). The “death holding” of xxx in the opponent’s suit, the blocking SA, the weak (even if very long) suit, were all warning signs that were duly noted. (I speak here as someone who would have a great deal of difficulty in finding this pass).

Curiously, though, the bidding success was followed by a trick lost in defense, enabling N-S to go plus in their 2H contract. The Ace of Spades was led, and West then shifted to a club; King of spades (club pitch), spade ruff, dA, and now, when West played a diamond, East did not really believe that his partner had passed with a 7-card suit headed by the AJ and a side Ace, and so ruffed small! Ida Grönkvist gratefully overruffed cheaply, drew trumps, and made 8 tricks.
​
But Singapore accepted the 9 IMPs (rather than the 11 they might have gotten if East had ruffed high).
