Do you bid differently if partner opens a strong no trump which gets doubled (say15-17) vs when partners’ overcalls 1Nt (15-18 with a stop over a major) ?

For simplicity, I generally play “systems on” when partner overcalls 1nt. This means we ignore the opening bid and just continue as if partner opened 1nt. If opener’s partner doubles the 1nt overcall our bids are the same is if partner opened 1nt and they doubled (for penalty), etc.

I accept that this is not “best” (in particular, we probably never want to play in opener’s five card major and could perhaps use sequences which show length in that suit some other way) but it works reasonably and it’s easy to remember.

15+ nt System's on, keep it simple

We use our runout seq., that applies if we open 1NT and they double us.

We have an escape sequence when we open 1n (10-13) or13-15). But when we overcall or bidding goes 1c -1d-1Nt doubled, seems like systems should be on vs trying to escape.

Two follow up questions. 1h them-1nt you-double them-2h me. Transfer or cue bid ? And 1h them -1nt-double -redouble me. For business or SOS?

We ignore the 1♥ bid and play exactly what we would after 1nt-(dbl for penalty). What I actually play here is different in various partnerships:

With Elianna, 2♥ is a transfer to spades and XX is running to a 5+ minor (1nt bidder is expected to bid 2♣ pass-or-correct).

With Sam, 2♥ is to play (obviously unlikely here) and XX is either 5+ clubs or 4/4 red suits (opener is expected to bid 2♣ pass-or-correct).

Thanks. In keeping it simple, I like the idea of just ignoring the opponents bids and systems on. But I guess in that case 1h them-1Nt you-double-2d I think would be cue bid, showing 4 card spade suit. Don’t know what kind of strength itt would show though. Care to comment/ agree or disagree?

A treatment I’ve seen (that seems reasonable) is transfer to their major showing exactly an invite with 5(+) in our major. This lets you get out in 2M (rather than 2nt/3M) when partner is minimum.

But it seems not very important to play this; I’ve been fine with “systems on” including transfer to their suit. Note that some players will open mediocre four-card majors (at least in 3rd seat) or even outright psych (again more likely in 3rd) so having a way to play in their suit is occasionally useful.

What is the X over a 1N opening?
