Hello friends

What do you bid with constructive support after interfrence to pd's 1M opening?

After X we play trfers and it is easy to show bad support or constructive. But after overcall with a suit by RHO we bid directly 2M with bad support (4-7hcp), dbl+supp with constructive (8-10). Sometimes there can be some problems bidding X+supp. Because pd thinks I have other suits. I like to know your suggestions.

Some players bid directly 2M with any support less than invite hand(5-9) like Tez. And a lot of players explains direct supp as "7 or less" What about yours?

5-9ish is normal. Not supporting immediately with support is a recipe for disaster, it's way worse than having a slightly wider range.

Hi,

there are various schemes out there to allow you to show different
raises.

If you like transfers => You may want to check out Rubens Advances.
As an alternative, you could use 2NT (besides the cue) for showing a
raise, if you do this, you have 3 ways to reach 3M

#1 jump
#2 via 2NT
#3 via the cue

This would allow you to show a preemptive raise, an inv.+ raise and a
constructive raise (which is also called a mixed raise)
If you search BBF with the key word "mixed raise" you should be able to
find post discussing various schemes.

For whats it worth - We play transfers, although in an exotic version, it
works, as long as you can remember it.

With kind regards
Marlowe

PS: It is not necessary, since this was already said by Justin: but I would
also like to stress the point - that it is more important to be able to show
the fit that to differentiate between the various raises, so if you just have the
standard setup av. (i.e. all inv.+ raises go via the cue, jumps are preemptive),
than this is enough to handle most of the cases.
With kind regards
