Hand Evaluation - 2NT ( Minor Slams )
PITBULLS:
Showing minors after a 2NT opener just involves have 3♠ as a relay to 3NT. Just
found out that Kantar plays the same treatment as we do with minors over 2NT but he adds a transfer element . Is it worth taxing our memory to implement it ? I do not
think so , therefore I took them out below. Also see
the 4NT bid by responder after the 3♠ relay to 3NT as minor suit Stayman . My partner came up with the concept of “picture bids” in these sequences to tell partner exactly how many controls are missing. This is a neat concept , you tell partner about the fit with the appropriate controls in one bid , by
jumping to game or slam. Jumping
to game tells responder we are missing 3 key cards , Jumping to slam says we
are missing 2 key cards & 4NT says we are missing 4 or more or no fit. Tom
came up with a 5♣ jump after the relay saying pass or correct to a minor.

Lets try on auction with the
“picture bid “ concept with a hand from Thurday nite. Partner opens 2NT , you have ♠KJ ♥AJx ♦Qx ♣J1098xx so you bid 3♠ & partner takes the relay to 3NT.
You bid 4♣ & partner with ♠Axx
♥Kxxx ♦Ax ♣AKQx leaps to 6♣ saying he is
missing exactly two key cards from the pre-determined scheme.
When the 2NT bidder lacks controls say ♠Qxx ♥KQx ♦KJx ♣AKQx , she can still bid 4NT with a 4 card
club fit as she lacks the controls to bid 5♣ , 6♣ or take control with
4♦
Kickback. The other hand now knows that she is missing at least 4 key cards as
defined in this scheme. Change partners hand by adding controls Ax Ax Axx
J10xxx so would bid 5NT saying “pick a slam”.
When partner is
showing a single suited hand it is probably 6
or 7 cards long. She is not interested in the length you have in
the suit but your overall controls.
Therefore , she is asking you to evaluate your slam potential with respect
to controls vrs
soft values. My partner opened 2NT with ♠Qxx ♥AKJx ♦Kx ♣AQJx , I bid 3♠ so he
took the relay to 3NT . I bid 4♦ showing a single
suited slam try in diamonds. Partner has enough controls to avoid bidding the
death response of 4NT. He bids 4♥ KCB so we get to our
baby +1370 in diamonds. I held ♠Ax ♥x ♦QJxxxx ♣Kxxx so his diamond control & the rest
of the hand , made 6♦ easy. Should I bid 5♣
after the 4NT death response ? No that is master minding as partner already
has told you she does not have a
suitable hand for any slam due to
“soft values “.
