I am curious about the auction.

My pard during this event is considered one of the top players of the club (regular partner of an ex World Champion), who has offered me to play with him for a mentorship to help me improve.

He is teachig me a 5 card major system developed by Garozzo and Zucchelli, full of gadgets rather new to me, and this was the first time I played it.

Perhaps the system is not effective, but I am not going to argue about the system effectiveness with a strong players who accepts to mentor me :rolleyes:

The auction went:

1C(1) - 2H (2)
2NT-3S


1) 1C(12-14/18-19 bal or clubs)
2) 2H = transfer to spades, 6+ bagger, either rubbish (0-5/6), or GF slammish
3) 2NT (shows extras, natural, 18-19 bal)
4) 3S = natural signoff

========

Almost nobody in italy (and for sure nobody at the Bologna club) plays the 1m-2S rubbish WJS, so I was expecting from the field, either a 1m - all pass OR a 1m-1S-2NT-3S auction at the other table.


============

To respond to Luis question:
the tourney was going very well, indeed this was the last board, and we won the event with 75% LOL (second pair had 60%)

Ok If we are doing well I play to go down 1 I can stand a 40% board or so. No reason to try for 80% or 0% on a finesse.

Down 1 for me.

I suspect that my original post is being misunderstood. I am not "curious" about the auction because it seems odd. Rather, I am wondering who was dealer, and who had a chance to make a call. This might enable better analysis as to options.

I also find the pips critical.

To re-explain, a tad further. Suppose that LHO had passed initially. Suppose, further, that his lead is the deuce and that the played pips and visible pips in dummy makes a suck of the Ace from RHO odd. This suggests a strange Ace underlead. An underlead of an Ace suggests that this was the least of all evils. I would expect, therefore, something like Qx-Axxx-Qxx-Axxx, except that this is too strong -- LHO might open with this. However, perhaps Qx-Axxx-Qxx-Kxxx??? That seems remote. But, an underlead of an ace certainly suggests that a diamond from trash might have been selected. Hence, if it appears that the heart lead was small from A-empty, I'd finesse.

A better scenario, more likely. What if the heart looks like a doubleton? This places the heart ace to the right. With AK of clubs, LHO would probably lead one, so I split those honors. Ducking the heart Ace, as opposed to rising and sending a small one back (lead-director), suggests that RHO has the King of clubs, LHO the Ace. The attack of a doubleton (6-1 unlikely for the 1C-P start) suggests that LHO holds Kxx and RHO QJ tight of spades. Thus, the doubleton lead suggests that RHO holds QJ-Axxxx-???-Kx(x). You cannot add in the diamond Queen and get a pass. Thus, I'd finesse.

Of course, all of this changes if the opponents are nutcases.

In any event, as I type this, I am having some difficulty visualizing any scenario where the heart is the lead and I win the first trick when the diamond finesse fails. The sole logical situation appears to be when LHO leads what appears to be small but might be MUD (the three, when I do not see the 2?), and when RHO sticks in a card that caters to a J-based lead. Then, I suspect that RHO holds diamond control and does not fear a pitch of the hearts on diamonds. So, if my Queen won the 10, or perhaps the 9, or even the 8 if the 9 is on dummy, I now get concerned.

Figuring this problem out using bidding theory and such seems less fruitful than using the psychology of the opponent's strange allowance of winning trick one in hearts, as well as restricted choice and the auction limitations.

1- Dummy was the dealer, opened 1st seat;

2- I do not remember the pips, sorry

=============================

Just for the record, in the actual hand both lines worked in this case:
LHO held Qxx in diamonds AND KJ9 in trumps, so after I ruffed out his DQ and cashed trump A, he ruffed the J of diamonds with a good trump.

I was simply curious about this choice because I was quite torn.
