我也找了个ERIC KOKISH发明的约定，这里2C同样是逼叫到局，开叫人再叫2D肯定有4张高花，叫2NT则可能有4张高花，这种情况下应叫人叫出高花通常应该是4张。
These rebids apply only when the bidding sequence has been 1D - 2C :
2D :5+ Diamonds, forcing
2H :4-4-4-1 distribution
2S :a good Club raise
2NT:12-14 HCPs, balanced distribution
3C :a bad Club raise
3D :16+ points and a 6-card Diamond suit
3H :a Splinter bid in support of Clubs
3S :also a Splinter bid in support of Clubs
3NT:18-19HCPs, balanced
