What would you think about these bids without a specific agreement?




Would you take 2 as a natural bid? maybe majors?



How do you read this double? takeout for the majors, penalty, cooperative?

Any difference if:




Thanks a lot,
Kind Regards,

I'd use whatever I do over a 1N opening. In the above cases
  • 2 transfer. I wouldn't bother with natural.
  • Whatever your 2 is. I play it as a 5-card non-promissory Stayman
  • Whatever you play over 2 interference, i.e Lebensohl, Transfer Lebensohl etc. bearing in mind that you are unlikely to have any GF bids unless long a major in which case Texas transfers apply.

#1 he is looking for a new partner.
I guess natural is sensible.

#2 T/O, dont be surprised to play 2Cx, i.e. it should deny a 5 card major

#3 No, X would still be T/O, keep it simple.
With kind regards

#1: A very popular agreement is to play system on after a 1NT overcall. Another very popular agreement is to play system on after a 1NT opening and 2 overcall. Taken together, I would expect the most common meaning here to be 5+ hearts, particularly amongst ADV+ players. A final thought is that a third popular agreement is to play that in 2-suited auctions, bidding RHO's suit is natural while bidding LHO's suit is artificial. So if the answer is not hearts then it is quite likely to be both majors. Either way, the 1NT bidder should probably just bid 2 now and wait to see what happens next.

#2: By the same logic as in #1, the most common meaning for this is Stayman, followed by takeout. Unless you are playing with someone who learned to bid under Culbertson, in which case it is clearly penalty. Aside from that one exception, Overcaller should just bid a 4 card major now without worrying too much about anything else.

#3: Yes, when the call over 1NT is 2 rather than 2, this makes a significant difference, since you can no longer play an easy system on scheme. In this case, the default amongst good players is TOX + natural + Lebensohl, while the default amongst club players tends to be Stolen Bid with the cue replacing GF Stayman. Weigh up your partner (and what your partner thinks of you) and then take the action that seems to present the least risk.

All good partnerships have agreements here.

One common agreement is ‘systems on’. So the bids mean whatever they’d mean had partner opened a strong 1N rather than overcalled. Since I won’t pretend to know what any particular plays, I won’t guess (but I play the 2D as a transfer and the double as stayman….)

It's so common to discuss this that it's a checkbox on the (ACBL) card.

I tend to play either "systems on" (and I know my agreement over 1NT-(2 natural), too) or "cuebid=stayman", so I know what all these sequences mean.

Over (1)-1NT-(2), I'd probably play my 1NT-(2) system. Might not be best, as that includes a takeout double, but partner has already shown diamond strength; if it's gooder than expected, I'm not going to yell at her if she passes...
