P2C
Responding to a Precision 2C Opening Bid
11
   Determine what the correct response to the precision 2C opener is.
   A general overview is:
   2D is a relay.
   2H/S/2NT are invitational.
   3C/4C are weak.
   3D/H/S are game forcing with that suit.
   3NT is to play.

   This flowchart also determines opener's rebid in all auctions
   in which he/she opened 2C.

1
Opener's rebid ?

Check to see if this is the responder's first bid or if it is opener's rebid.

Interference ?
1
Did your RHO interfere?

2
Interference at
two-level ?
1
Did the opponents make a simple overcall of 2D, 2H, or 2S?

1
Did RHO double?
3
If your rho doubled you have been given a free bid.
Normal systems will be on.
Redouble will show a good hand.  So, check to see if RHO doubled.

1
Redouble ?
1
Do you have a hand interested in redoubling?

1
Rho bid 2D ?
2
If your rho bid 2D, than Double is stolen bid and all other bids are the
same as if there was no interference.

Doubles are negative through 3S.
With significant club length compete to 4C or bid 5C.

1
Weak hand ?
2
With less than 8 points you have a weak hand and your only possible
bids are club raises.

1
Club support ?
3
With 4-7 points and 3 or 4 card support bid 3C.
5 card support bid 4+ card support bid 4C.

With a singleton or a void and trump support you may want to splinter.
Without a singleton or void you may want to jump to 3NT.
You also need to have 4 card trump support in order to splinter.

A jump to the 4 level in Diamonds, Hearts, or Spades shows a splinter

Check to see if this is in the middle of the 2D relay or if partner responded
with something else.

1

1
Which major ?

Bid your four card major at the 2 level.

1
Weak or strong ?
3
With 13 or more points you want to make an accepting bid of 2NT.

than 4 diamonds. With less than 13, bid 3C.

1
Interference ?
1
Did either of the opponents bid?

2
Did partner bid
two of a major ?
1
Did your partner respond with a 2 of a major?

1
How strong ?
7
Partner's hand is limited to 8-12 points and he has 5 of the suit he bid.
The contract must be placed. Possible bids are: 
Pass with tolerance for his suit and a minimum.
Invite with extras and 3 card support.
Rebid clubs with a long club suit and a minimum.
Invite in NT with a relatively balanced hand and no support.
Bid the other major suit or diamonds to show 5-4 and a good hand.

1
Did partner raise you ?
3
Did partner respond three clubs, four clubs, or five clubs.
If he/she did it is correct to pass.
It is also correct to pass if partner bid 3NT.

2
Did partner
bid 2NT ?
1
Did partner responded with an invitational 2NT?

1
Min or max ?
2
Partner has made an invitational 10-12 point bid, so you should place
the contract.

2
Have support
for major ?
1
Was partner's bid a major suit and do you have support?

1
Have extras ?
2
Usually it is right to sign off, except with a very good hand you can try
to cue-bid.

1
NT suitable?
7
Now your main objective is to try to find a 3NT game. If you have stoppers
in both unbid suits, bid 3NT. If you have an unbid 4 card suit that you
can bid below 3NT, then bid it. Otherwise if you have 2 card major suit
support, raise partner to 4. If you are balanced and have 1 stopper it is
still a good idea to bid 3NT. If you have minor suit support and are
distributional bid that. If you have a really long club suit, you can
rebid it as well.

1
LHO or RHO ?
1
Did your left-hand-opponent overcall or was it your right-hand-opponent?

2
Did RHO 
also interfere ?
1
If your RHO bid than you are no longer going to be forced to bid.

2
Did partner make
a 2D relay?
3
Check to see whether partner made the 2D relay bid.
This is possible even though LHO overcalled, because partner can make
a stolen bid double of 2D or LHO may have doubled.

1

3
If you can bid at the three level, do so normally.
Otherwise it is usually right to pass.
With 4 cards in the opponent's suit, you should double.

2
Did partner pass
or double ?
1
Check to see if partner passed or doubled

1
Reason to bid ?
5
You should usually pass in these situations.
If partner has passed you must be very distributional to bid again.
If partner has made a negative double you must have at least 4 card
support for his suit. If partner has made a penalty double,
you can also make a penalty double with cards in RHO's suit.

2
Did partner
bid clubs ?
1
Check to see if partner bid clubs.

1
Right to pass ?
3
It is almost always right to pass in this situation.
The only situation in which you want to bid is in order to sacrifice
and even that should be left to partner under most circumstances.

2
Did partner
bid NT ?
1
Check to see if partner bid NT.

2
Length in
RHO's suit ?
3
Your partner has bid NT, so you are looking to double.
If you have 3 or more cards in RHO's suit, make a penalty double.
Otherwise it is probably best to pass and let partner decide what to do.

1
Support for partner ?
2
You should usually pass unless you have support for partner.
If you have support for partner raise his bid as cheaply as possible.

1
