part 1After we open and opponent interfere in level 1 we need agreements with partner from what is now the meaning of Responder's bids.
Thus here we propose some rules to be follow by Responder:
RULE#1: After an open in a minor suit (1
/1),
independent of any interference at level 1 or 2, the asking for aces
will be made using the Gerber Conventions bidding 4
and the responses are:4
= 0 or 4 aces. 4= 1 ace, 4= 2
aces and 4nt= 3 aces. After the Opener response of his aces any bid by Responder is conclusive and so Opener must pass. In case of interference DOPI (Double zero, Pass one, next suit = 2 aces and next+1 suit = 3 aces). Examples:
Opener Overcaller Responder (having strong hand)
1
1 4
<= Gerber - ex AQ10 x KQ87xx K98 1
1
4
<= Gerber - ex KQJ Kx x AQ98542 1
double 4
<= Gerber - ex x x KQJ743 AQJ82 1
double 4
<= Gerber - ex AQ x KQ108 KQJ987
RULE#2: After an open in a minor (1
/1),
independent of any interference at level 1 or 2, the
response 4
is a transfer to 4
showing 7/8 cards Hearts and up to 9 hcp without 2 aces and in similar
way the response 4
is a transfer to 4.

=>AKJ98xx xx xx xx Rule#03 - After we open in a suit at level 1 and opponent bid a takeout double our priority is to inform Opener about our strength with 10+ or less than 10 hcp and Responder do that bidding redouble or bidding anything else:
Opener Opponent Responder
1
double redouble <= 10+ hcp 1
double redouble <= 10+ hcp1
double redouble <= 10+ hcp1
double redouble <= 10+ hcp1
double any bid level 1 or 2 <= less
than 10 hcp 1
double any bid level 1 or 2 <= less than 10 hcp1
double any bid level 1 or 2 <= less
than 10 hcp1
double any bid level 1 or 2 <= less than 10 hcpNote1: after redouble all doubles are penalty, but a player should not let partner double at level 1 or level 2 when he is shorter (zero/1 card) in opponent suit principally when the opponent suit is bidded by the partner of the doubler (Advancer) because in this case opponents may have a 8 cards fit.
Note2: of course there are some bids by Responder that he will not redouble like when he bids game, splinters or agreements showing support (like in Jordan conventions) and a strength not for punish opponents at level 1 or 2 but to play in opener's suit.
Note3: a double, after redouble, should be done when:
1- we have more strength in honors than opponents;
2- simultaneously we don't have support to partner's suit and presume that a misfit may occurs in this board;
3- we have 4+ cards with honors in the opponent suit.
Rule#04 - We don't redouble having balanced hand with 4 cards support in partner's major suit or 5 cards support in partner's minor suit and we bid 2nt showing 10-11 hcp (Jordan convention):
Opener Opponent Responder
1
double 2nt <= 10-11 hcp with 5+
cards 1
double 2nt <= 10-11 hcp with 5+
cards1
double 2nt <= 10-11 hcp with 4
cards balanced hand1
double 2nt <= 10-11 hcp with 4
cards balanced hand1
double 4 <= 10-11 hcp with
5+
cards no singleton1
double 4
<= 10-11 hcp with 5+
cards no singleton1
double 3 <=
splinter 10-11 hcp shorter in
with
4+ 1
double 4 <=
splinter 10-11 hcp shorter in
with
4+ 1
double 4 <=
splinter 10-11 hcp shorter in
with
4+ 1
double 4
<= splinter 10-11 hcp shorter in
with 4+ 1
double 4
<= splinter 10-11 hcp shorter in
with 4+ 1
double 4
<= splinter 10-11 hcp shorter in
with 4+ After Jordan (10-11 hcp) if Opener rebids his suit this is sign-off.
Rule#05 - After an opening in a minor suit and a takeout double by opponent Responder bidding a suit shows 5+ cards and less than 10 hcp - not forcing, so Opener can pass with 2 cards:
