打伯根式加叫能为你们的高花进局试探结构增添新的内涵。了解到同伴有三张支持，你可能更愿意做3NT，而不做10墩的高花定约。试局的目的不仅是叫到局，而且要叫到正确的局。我喜欢考克什(Kokish)的进局试探叫，它们是很好的探索工具，能找到正确的局。
1H-2H：6-9点，准确的三张H支持
2S：Kokish进局试探——所有花色的长套试探叫，问同伴是否接受邀请， 准备接受那个长套的进局邀请
2NT：接受S的长套邀请。开叫人可以3H或4H止叫，或者再叫花色做第二次进局试探或开始扣叫
3C：接受C的进局试探但不接受S的进局邀请
3D：接受D的进局试探但不接受S/C的进局邀请
3H：拒绝接受邀请
4H/3NT：接受所有花色的进局邀请
2NT：S短套试探或更好
3C：C短套试探或更好
3D：D短套试探或更好
3H：H短套试探或更好
3S：6-4套或点力极端集中的5-4套
3NT：5332，不逼叫
4H：止叫
1S-2S：6-9点，准确的三张S支持
2NT：Kokish进局试探——任何花色的长套试探叫，问同伴是否接受邀请，准备接受那个长套的进局邀请
3C：接受C的长套邀请。开叫人可以3S或4S止叫，或者再叫花色做第二次进局试探或开始扣叫
3D：接受 D的进局试探但不接受C的进局邀请
3H：接受H的进局试探但不接受C/ D的进局邀请
3S： 拒绝接受邀请
4S/3NT：接受所有花色的进局邀请
3 C：C短套试探或更好
3 D：D短套试探或更好
3 H：H短套试探或更好
3 S：阻击性，六张套
3NT：5332，不逼叫
4S：止叫
通过这些叫法获得的信息可能使你更愿意叫3NT而不是4高花。你通常叫的是有实力的花色，而这可能更宜于将定约引向3NT定约。如果你有点象彼得·琼斯(Peter Jones)，总是碰上坏的将牌分布，那这个进局邀请结构可能就更有用了。
我想象不出在伯根式3D加叫之后怎么试局。总不能用跳到局来作为进局试探叫吧！！而在伯根式3C加叫之后，我猜想，你可以发明几种试局叫法。也许，3D叫品可用作以大牌点为基础的一般性试局。要是试S局，你也有可能打H定约，你可以为相应的叫品规定含义。

Kokish Game Tries
PITBULLS :
Playing Bergen raises adds a new dimension to your major game try structure . Knowing that partner always has 3 trump makes 3NT a powerful alternative to a 10 trick contract . Getting to the right game can be considered as well as getting to game period . I like the Kokish game tries as a good exploratory tool to find the right game.
1 H-2 H: 6-9, exactly 3 H.
2 S: Kokish Game Try, a long suit trial in any suit, asking partner which Game Try suit she would have accepted.
2 NT: Accepts a game try in S. Opener now signs of in 3 or 4 H, makes a second game-try by bidding the suit or starts to cuebid.
3 C: Accepts a game try in C, but not in S.
3 D: Accepts a game try in D, but not in S/ C.
3 H: Rejects all game tries.
4 H /3 NT: Accepts all game tries.
2 NT: x/- S, Short suit Game Try or better.
3 C: Short suit Game Try or better.
3 D: Short suit Game Try or better.
3 H: Preemptive, 6 card suit.
3 S: 6 4 or extremely concentrated 5 4.
3 NT: 5332, proposal to play.
4 H: SO
1 S-2 S: 6-9, exactly 3 S.
2 NT: Kokish Game Try, a long suit trial in any suit, asking partner which Game Try suit she would have accepted.
3 C: Accepts a game try in C . Opener now signs of in 3 or 4 S, makes a second game-try by bidding the suit or starts to cuebid.
3 D: Accepts a game try in D, but not in C.
3 H: Accepts a game try in H, but not in C/ D.
3 S: Rejects all game tries.
4 S:/3 NT Accepts all game tries.
3 C: Short suit Game Try or better.
3 D: Short suit Game Try or better.
3 H: Short suit Game Try or better.
3 S: Preemptive, 6 card suit.
3 NT: 5332, proposal to play.
4 S: SO
The type of information obtained by these bids can lead to 3NT instead of 4 of a major . You are normally bidding values in that suit and that could lead to 3NT. If you are like Peter Jones and have a propensity for bad trump breaks then this tool would be very useful.
I can not see making a game try over a major Bergen 3D bid . A game try should be a jump to game !! A Bergen 3C raise you can invent some game tries I guess. Perhaps a 3D bid can be a general game try based on HCP . With spades you also have hearts to play with so you can invent a meaning for that bid .
