Hand Evaluation – 4♠ Exclusion KCB (hearts )
PITBULLS:
Most
expert pairs have adopted the Italian style of Q bidding. Using this philosophy , going to
the 5 level or forcing the contract to the 5 level by a Q bid is a systemic no-no. Last train slam tries were
invented to prevent going to the 5 level with a Q bidding auction. Last train
slam tries are especially handy in splinter auctions to the 4 level. Kickback
KCB was also invented to keep the auction at the lowest possible level while
doing your query.
One
aspect of Kickback , I have never liked is having 4♠ as Ace asking with hearts agreed as the trump suit. 4NT means KCB to me
whenever we have a major fit.
Since a 4♠ Q bid forces you
beyond the 4♥ game level , I suggest that
such a bid be defined
as Exclusion KCB. This treatment
is close to being Kickback but a lot more useful as 4NT will still functions
quite well as KCB , thank you. With hearts agreed , bidding 4♠ as a Q bid is usually ludicrous.
Here
is an auction from a Spingold . Partner opens 1♣ , you
have ♠void ♥AKQxxx ♦Kxx ♣QJxx . You respond 1♥ & partner rebids
1NT . Your partnership has a number of forcing bids
you can use, but I like the “ recovering the strong
jump shift” bid of 3♥. This brings a 4♣
bid by partner so you bid 4♦. Partner now bids 4♥ so in these auctions
if you have a spade control & are in slam mode ,
you would bid 4NT. With your void , you bid exclusion
KCB instead. Partner bids 5♦ showing two Aces
outside spades. I like repeating
exclusion as specific king asking so you bid 5♠. Partner bids 6♣
showing the king. Since you have already shown the diamond king as a Q bid , you now bid 6♦. This can only be
interpreted as a suit ask for the queen. Partner bids
7♥ with ♠Jxx ♥xxx ♦AQx ♣AKxx .
If
you do not use 4♠ as KCB with hearts agreed , use the bid as exclusion. Also with hearts agreed a direct jump to 4♠ is Exclusion KCB.
1♦-P-1♥-P
2♥-P-4♠* Exclusion KCB
Even with
a minor agreed , a leap to 4♠ should be
exclusion KCB as long as the jump was two levels. If the jump was one level , a splinter is identified.
1♦-P-1♥-P
2♦-P-4♠ A jump shift reverse by responder is
undefined so that should be exclusion in support of diamonds.
1♦-P-2♣-P
2♦-P-4♠ This auction should not be
natural as there was a 2♠ bid available.
