Kokish game tries

Eric Kokish came up with what he called two-way game tries.

1Spade Pass 2Spade Pass
?

When opener relays with 2NT (asking for a help suit), responder will bid the cheapest suit in which they would accept a help-suit game try. So if responder has SpadeQT6 HeartJ84 DiamondKQ632 Club86, they'll bid 3Diamond over 2NT. This not only tells partner about help in diamonds, but since 3Club was skipped over, opener knows that responder has a poor club holding.

So let's say the auction went 1Spade - 2Spade - 2NT [asking] - 3Club [showing goodies in clubs], but opener wasn't interested in the club suit. They can now bid 3Diamond or 3Heart, asking for help there. So, theoretically, an auction might go like this:

1Spade Pass 2Spade Pass
2NT* Pass 3Club** Pass
3Diamond*** Pass 3Heart**** Pass
4Spade

* Game Try
** Would accept a game try in Clubs
*** Can you help me with diamonds?
**** No but I have heart help

It gets just a bit trickier for a lot of folks when hearts are trumps. If we were to use 2NT as the "help-suit ask" over 2Heart, there would be no way to show spade help-- so we use 2Spade as the asking bid.

1Heart Pass 2Heart Pass
?

One more little space-saving maneuver: When partner asks with 2Spade, to show spade help we bid 2NT.

So if the auction goes:

1Heart Pass 2Heart Pass
2Spade* Pass 3Club**

*Game Try
**[stuff in clubs], denying help in spades (the "cheapest" suit)
