RESPONDING TO PARTNERŐS OVERCALL
By Tony Russ
When partner overcalls he may
have anything from 7 to 17 points. The only sure thing is that he has at least
a five card suit. By the way I would always prefer to overcall rather than to
double with single suited top end hands. What am I to do if I have 16 points
and 6 spades and the bidding goes:
West North (me) East South
1H Double 4H Pass
Pass ?
South can hardly be expected
to bid with say 8 pts and 3 spades but is much more likely to compete knowing
about my long spades. Also the most likely place to have a fit is in my longest
suit so I think itŐs best to bid it so as to compete for the part score
effectively. Doubling suggests shortage in their suit and reasonable support
for all the others and not a single suited hand.
So how does one respond to an
overcall when the points range is so wide?
One approach is to base
direct suit raises purely on the number of trumps held. For example if partner
overcalls 1S, I will raise to 2S holding three trumps, to 3S holding four
trumps and to 4S holding five or more trumps regardless of the number of points
held (but taking adverse vulnerability into account) This method is based on
the Law of Total Tricks from which comes the Law of Total Trumps which suggests
that you are safe to bid to the level of the number of trumps held between the
two hands. More of this in a future edition.
Without such trump support
and with game interest we need to discover whether partner has a good overcall
or a Ôbag of nailsŐ. We can use the ridiculously named Unassuming Cue Bid for
this purpose. Say left hand opponent (LHO) opens 1C, partner overcalls 1S and
RHO passes. What would 2C from you mean? Well if you play UCBs it suggests some
support for partner and asks him to reveal the strength of his hand. A simple
rebid of his overcall at the lowest level would indicate the bag of nails.
Anything else suggests a decent overcall.
What do you do with a decent
hand but little support for partnerŐs suit? It depends on how you treat a change
of suit after the overcall. If this is not forcing then you must either pass or
use the UCB without the required support of partnerŐs suit. This is OK if you
are strong enough to bid on in any case. I prefer to treat a change of suit
after an overcall as a one round force. After all it is not illegal for partner
to have support for my suit as well as one of his own.
And what
about a 1NT response to partnerŐs overcall? Realising that he may (usually will) be short of an
opening bid by as much as 5 points I suggest that you add at least four points
onto your normal requirements of a 1NT response to an opening bid. So if your
1NT response to partnerŐs opening1H shows 6-9 points I suggest that after an
overcall of 1H it should show 10-13 points.
This is a very brief summary of a big topic and I hope to enlarge on it in future editions but I would be interested to hear and to publish your views too.
