Mr. Eric Kokish, a bridge expert and theoretician, believes that most experts are correct in the opinion, that two-suited hands should not be opened with the Artificial, Strong 2 Clubs bid. Therefore, when the 2 Clubs opener shows a second suit, it is expected to be a 4-card suit. This stipulation affects some of the recommended sequences. In the discussion below, an Ace is 2 controls, and a King is 1 control.

Opening 2 Clubs

When the opener bids an artificial, strong 2 Clubs, the responder can bid:

2 : shows zero or one control, and no special suits as below.
2 : shows two (2) controls, and no special suits as below.
2 : shows three (3) controls, and no special suits as below.
2 NT: shows any 6-card or longer suit with an expected one loser opposite a void. This includes any 6-card suit with four of the top 5 honors except AKQTxx is not included.
3 any suit: Three-level suit bids are transfers, Spades transferring to Clubs. They show a 6-card or longer suit that would have an expected no losers opposite an honor, but could have more than one loser opposite a void. This includes any 6-card suit with three of the top 4 honors except AKQxxx is not included.
3 NT: shows an undisclosed solid suit. A solid suit is defined as AKQJxx or AKQTxxx, or better. Mr. Eric Kokish recommends that a 4 No Trump rebid by the opener in this sequence asks the length of responder's suit, although it makes sense also to play that bidding responder's Minor suit at the four level could also be length asking. The opener should be able to tell what suit the responder has.
4 any suit: Four-level suit bids are transfers, Spades transferring to Clubs. They show a broken 8-card (or longer) suit.
   

An Example should clarify:

Opener Responder Meaning
2 Artificial. Strong. Forcing.
2 Artificial. Zero or 1 Control
2 Forcing. Either a genuine Heart suit or a balanced holding with 25 or more high card points.

Special note: the opener's rebids above 3 No Trump have been fabricated by Mr. Eric Kokish, and are open to discussion. The opener may show a solid Heart suit via an immediate leap to 3 over the 2 response. This sets the trump suit.

The possible rebids by the opener after a 2 second response are:

2 NT: The opener has a balanced 25+ high card points. Game force. The responder uses the usual tools to continue.
3 : The opener has 5(+) Hearts and an expected 4-card Club suit. Forcing.
3 : The opener has 5(+) Hearts and an expected 4-card Diamond suit Forcing.
3 : The opener usually has 6 or more Hearts, but the suit is not solid. Forcing. The opener could have a balanced hand with 5 Hearts, lacking a stopper for No Trump.
3 : The opener has 5(+) Hearts and and expected 4-card Spade suit. Forcing.
3 NT: The opener has a 6-card Heart suit with stoppers, the Heart suit is not solid.
4 : The opener has a 3-card fragment with 2 of the top 3 honors in Clubs with a long Heart suit playable opposite a void (4 of the top 5 honors, but not including AKQJxx).
4 : The opener has a 3-card fragment with 2 of the top 3 honors in Diamonds and a long Heart suit playable opposite a void (4 of the top 5 honors, but not including solid suits.
4 : The opener has a 3-card fragment in Spades with 2 of the top 3 honors, and a long Heart suit playable opposite a void (4 of the top 5 honors, but not including solid suits.
4 : Transfers to 4 No Trump. The opener has a Heart suit, and the ability to run the top 11 tricks at No Trump. Invites a slam. Responder's Kx will be good. Responder's KQx will be worth a grand slam.
4 NT: Roman Keycard Blackwood, Hearts is the trump suit. The responder answers as if the four Kings and the Queen of Hearts were the Key Cards.

The schematic for responding to 4 No Trump:

5 : 1 King or the Queen of Hearts.
5 : No Key Cards.
5 : 1 King and the Queen of Hearts, but not the Jack of Hearts.
5 : 1 King and the Queen of Hearts and also the Jack of Hearts.
