agree:smile_38:

但其實(in bbo),叫2H /3H的人是一半半的

BeSmart 2007-11-15 01:56 AM

I can say, 3H is simply wrong as 2H is forcing and unlimited.

In modern approach, 3H would be treated as non-forcing (invitational) or mini-splinter.

Bidding low also help you to know your partner layout so as to identify the best slam. (For your information, you need only SA, HJ, DQJ, CA to make a 7NT)

唔係好明:smile_13:
2H可以慢慢叫上去, 取得更多的資訊
if 2H is unlimited, 咁如何分別高限與低限...
如何能使partner知自己有game/ slam interest:smile_13:


btw, 如果那12分是這樣分配就太美妙了

In SAYC, 2H is 10HCP+, in 2/1, 2H is 12HCP+.

Both approaches has unlimited HCP, even though you have 30HCP, if the distribution suits, you could only bid that. Therefore, your partner has an obligation to bid once more.

From the rebid of the opener, you would know more information. For example in SAYC, if your partner jumps to 4S/3NT, then you know your partner is holding a good hand; if your partner bids 2S, probably he can merely open 1S and the chance of slam would be less.

In a nutshell, although you cannot show your HCP range, you can use the bid to drive your partner telling useful information to you, so disclosure of hand from you is no need.

If you are using 2/1, cue bids are enough for you to show slam interest; for SAYC, I would like to introduce 4th suit GF for you to continue the bidding.

thanks:loveliness:  just some follow up questions if i am using sayc:smile_13:

1. if  1S-2H-2S (partner 低限), 自己有16分就直上4H/ 4S?

2. if 1S-2H-3C 是否表示partner最少有中限(14+) and game interest?

alexskt 2007-11-15 05:48 PM

but jump bid implies that your hand is very nice

For the first question, YES! But I would bid a 3D to force one more round and gather more information as the chance of slam is still there. (In here, 3D acts as a pseudo suit)

For the second question, I would interpret like that and therefore it is a game forcing bid. 3H can be used to emphasize the strength in H.

咁rebid 3D, 有無話要d咩要求 (第二長門/ 有檔) or just a 逼叫

BeSmart 2007-11-16 03:23 PM

Indeed, what 3D here should be known as showing second suit and the bid itself is forcing. However, in SAYC, all rebids would be regarded as non-forcing. While the case here is too early to use 4NT, the only thing you can do here is to use a new suit to continue gathering more information.

So basically, if you wanna force your partner to bid, no matter how short is the suit, you might have to bid it in order not to let the bidding ends. The better unbid suit would normally be adopted for this purpose, like 3D here.

And this is one of the main reason of why 2/1 is superior than SAYC.

kw7796 2007-11-17 05:48 AM

雖然好似已經有答案, 但都照出case 2:

It's just my opinion, you may disagree. But while this example reflects the weakness of SAYC. I currently don't see any weaker point in 2/1 except 1H/1S - 1N.

haha, u've already mentioned one drawback in 2/1

true that 2/1 can provide a clear differentiation at early stage
meanwhile SAYC can provide a more flexible bidding spaces for u ( of coz that will require judgement)

tools are here, it's noly whether the user can utilize it
