Hand Evaluation – Tactics ( Recovering your Major Fit )
PITBULLS:
We
play a 5 card major system where
we will open a minor with a 4 card major or 4-4 in the majors. This practice
allows us to lose our
major fit sometimes. How ? when the opponents pre-empt
you from uncovering your 4-4
major fit. One surprisingly pre-emptive
bid is the 1NT overcall by the opponents. You are pre-empted from
discovering your major
fit. Kokish , among others, decided to do something about it. Kiz Fung taught us the basics but here is the full version. The Kokish system does not apply
if you open a major.
When
you open 1 of a minor &
they overcall 1NT , 2♣ by responder is
like Stayman but showing
both majors. 2♦ directly by
responder shows at least a 4 card fit for partner’s
minor with a 4 card major. A jump in a minor is pre-emptive whether
it is in a new minor or partners
minor. 2NT is shows at least 6 of the other
minor with 4 of partners minor. 2♥/♠ is natural
& under the strength of a penalty double. A double is for penalty.
Here
is an example hand that I held playing with Kiz
against Ray Grace in the Red Deer Calcutta. Kiz
opened 1♣ , Ray overcalled 1NT & I held ♠Kxxxx ♥J10xxx ♦xx ♣x & bid 2♣. They bid 3NT & Kiz doubled. When partner opens a minor, it is not a natural lead. When partner doubles 3NT after opening a
minor, the
double says lead my
minor. I dutifully did & Kiz held ♦x ♥AKQx ♦xxx ♣Axxxx . Kiz
knew 3NT was going down based on my major
suit bid so she doubled to get me off
the spade lead. If I had led a spade , they damn near
would make 3NT. Kiz won her club Ace & we cashed
our 5♥ tricks.
Another
sample hand . Partner opens 1♣ with a 1NT
overcall by their side. You hold ♠AJ10x ♥xxx ♦x ♣Qxxxx so you bid 2♦ which shows a fit for partners minor with a 4 card
major. Partner bids 2♥ so now what ? Bid 2♠ in case partner has both 4 card majors.
You have already shown your minor fit so if partner does not like spades , she retreats to clubs.
This
scheme allows you to support partners diamonds at the two level provided you have a 4 card major on the side. ♠xx ♥AKxx ♦xxxxx ♣xx
1♦-1NT-2♦-P
2♥
Playing
2♣/♦ as natural after a 1NT overcall is a waste of time. The
opposition will always outbid
you in partials
with the strength of their NT overcall in the equation. The only chance you
have of buying the contract in a minor , is getting it
up to the 3 level. Yes , there is some risk but double partial swings are
expensive in IMPS as well as matchpoints.
