Hey guys.

Recently I came across this convention in Kokish system notes; sure seemed interesting. Then i found it in a couple of world class convention cards (think it was Diego Brenner's), yet the developments we're kinda lacking.

I'd really appreciate some insight on how the sequences go (namely, how opener acts after a minor suit transfer).

Thanks!

I think what you are refering is to the sequence called rubenshol


1♥-(2♠)-

now...
2NT =♣
3♣=♦
3♦=♥
3♥= for whatever you want (we use it for limit raise)
3♠= strong heart raise


But the same principle applies after:

1♠-(2♥)

when everything is transfer now.

But we don't stop there either, we also use it when

1m-(2M)-

And also after

1M-(2M) (michaels)

....



How does opener react now?


It depends on your requirements for bidding a transfer to a minor, some people think all you need is a good suit (♣KJ10xxxx ♦Kxx and out) and there is another trend that thinks it should show at least limit values or more (like a standard 2/1)

with minimums opener is suposed to acept the transfer, even with singleton, with support he should jump to 4 with minimums (or gamble 3NT) and cuebid with extras, and the rest pretty natural, rebidding your suit bypassing the transfer shows extras.

Thanks!

Was thinking about how would this work with a weak NT structure. Should a competitive minor transfer mean gameforcing against a 15-17 balanced? If so, opener doesnt accept transfer with a balanced hand?

So, after 1♥ - (2♠) - 2NT - p

3♣ A minimum unbalanced, 2♣+
3♦ Natural, forcing?
3♥ Natural, should be forcing?
3♠ Nice club support
3NT Definitely with ♠ good stop, but big range.

Should it go that way or would 3♦s be artificial?

Thank you.

My experience playing weak NT is zero, so won't help you much.

My advice is to treat non fitting intermediate hands as minimum fitting hands and accept the transfer. But off course gamble 3NT when it seems right.

IMO rebidding your suit instead of accepting the transfer should always be strong.

Oh, well.

Thanks anyway.

After 1H - (2S) you could play:

Dbl = negative.
2NT = constructive with clubs or diamonds, or strong with clubs.
3C = inv+ with diamonds.
3D = inv+ with hearts.
3H = constructive with hearts.
3S = GF, often clubs without a stopper.

Similarly after 1D - p - 1H - (2S):

Dbl = TO.
2NT = min with both minors or diamonds, or GF with both minors.
3C = inv+ with diamonds.
3D = inv+ with hearts.
3H = min heart raise.
3S = GF with both minors, no spade stop.

The biggest problem is the inability to bid a natural 2NT. If you play that 1D denies a strong balanced hand then this is less of a loss.
