Board 13 was a push but it could have been a small swing
for either side, a simple 2nt contract was duplicated and
could first, and should have been set at both tables.

Open Room:

Luis Fred Ana Inquiry
-------------------------------
1d 1s p
1n p p 2c
2n p p p
-------------------------------

Everything was natural and sensible EW reaching 2nt after trying to buy the
hand at the 1 level. Fred lead the dK ducked and continued with the dQ. After
this start the defense can cash 4 diamonds, 2 hearts and 1 club for down 1.
Declarer has to stablish a club trick inmediately before the defense can
stablish diamonds. Luis took the 2nd diamond and wrongly played a diamond
back, Fred winning and exiting with a diamond. Now declarer cashed the 5 spades
and played a devilish low club from the table. Inquiry failed to smell the rat
and played low. The cQ was the 8th trick for declarer.

Closed Room:

Malucy Marston Skystne Sartaj
--------------------------------
1d 1s p
2n p p p
--------------------------------

Marston also opened 1d but this time showing 9-14 and 4+ hearts. Malucy took
the 1s overcall more seriourly than Luis and invited directly with 2NT silencing
south who never showed his clubs. Declarer took the dK lead and played hearts
inmediately, this seems to be again very wrong since now the defense can stablish
4 diamonds, 2 hearts and the club ace for down 1. Marston cashed the dQ and Sartaj
signaled heavily with the cJ, Marston now wrongly played a club and that stablished
and 8th trick for declarer. It's a difficult hand as we can see both declarers
didn't want to risk a big set vulnerable by playing clubs themselves so they both
gave a chance to the defense, Gitelman got it right and never played clubs but then
South slept in the ending. In the other table Marston switch to clubs before stablishing
the diamonds looks wrong since Sartaj can't have an entry to his club suit and you can
count 6 defensive tricks if he has the cA. Complex hand.

A partscore appeared in board 14, the neturalists that
are playing against a supossed more agressive system
managed to buy the hand at both rooms.

Open Room:

Luis Fred Ana Inquiry
-------------------------------
p 2h
p p p
-------------------------------

After a normal weak 2 in hearts by Inquiry Luis showed
a mixture between judgement and state of the match by
passing 2h. Without any atractive lead he lead the dQ,
a low spade would have been better on this layout.
The dQ was covered to the Ace east returning another
diamond. Inquiry won the 2nd diamond in hand to play
a club to the K winning the trick, now he ruffed a
club and played a spade, west contributed a very
odd-looking 9 and declarer missguessed. Back came
a diamond ruffed with the h2, Luis cashed the hA and
exited with the cA ruffed. Now declarer ruffed his
sT that was good in dummy and ruffed another club
back to hand he exited with a low heart to the K
and won the last 2 tricks with the hQ and hA, a strange
elopement in curious hand.

Closed Room:

Malucy Marston Skystne Sartaj
--------------------------------
p 2d
2s p p p
--------------------------------

Sartaj opened a not-so-multi 2d that can only be a weak 2 in
a major and Malucy interposed a dangerous 2s overcall. He was
left to play there.
Marston lead his singleton heart Sartaj winning the Ace to play
his singleton club. Declarer started trumps playing the Ace
and low to the Q Marston wining the K. Marston cashed the cQ
and cK and played a fourth round that Sartaj could ruff with the
sT. Declarer had still one diamond loser so he was down 1 on very
good defense. In this board is complex to analize who should play
what and how and the result was 2 imps for the naturalists 40-8.

A normal NT game for NS where they can take
all the tricks without a heart lead due to the
favorable layout in the minors and spades.

Open Room:

Luis Fred Ana Inquiry
-------------------------------
1n
p 2s p 2n
p 3d p 3n
p p p

2s was a transfer to clubs and 2n showed a super-accept, Inquiry
decided that his excellent 17 counter with JT of trumps was equivalent
to Hxx in clubs. Fred bid his second suit and Inquiry showed is excellent
stoppers bidding 3nt. Luis found the only lead to hold declarer to only
12 tricks in the very favorable layout he lead the h8 and
Ana raised with the Ace. -690 to the naturalists.

Closed Room:

--------------------------------

1c was strong 1d showed a forcing game hand with 11+ HCP, Skystone interposed
a lead directing 1h overcall and then bidding proceeded naturally to the NT
game. Malucy found the heart lead but it was easier for him after the 1h
overcall. No swing. Still 40-8 for the Mosqitos.

-------------------------------

Luis opened a normal 1s and Fred overcalled in diamonds, Ana had
to pass and Inquiry showed his good hand with a cuebid, now Luis
bid spades again and Ana made the very good decision to bid 4s,
Inquiry passed and Fred took the right decision to bid 5d. There
wasn't any excitement in the play declarer losing 2 spades and
one club for a quick down 1.

Closed Room:

Malucy Marston Skystne Sartaj
--------------------------------
1s 2d p 2s

--------------------------------

An identical auction in both rooms is not usual in a naturalists vrs
scientists event, this could have happened here had Marston bid 5d
duplicating the open room auction however he choose to pass and
the naturalists were allowed to play 4s on the singleton club lead.

Declarer won the cK in hand and played a diamond, Sartaj winning the dJ
to play a trump. Declarer took the trump switch in hand and ruffed a
diamond he was locked in dummy so he tried the effect of running the hJ,
an interesting maneouver, Marston win the hQ and underlead his hA to Sartaj's
king who promptly returned a club for down 1. Very well defended. This
added 4 extra imps to the scientists now ahead 44-8.
