Print
2 club openings cover several types of hand:
  • balanced hands with at least 22-23HCP (super NT),
  • third-zone one-suiter hands with a strong suit of at least 6 cards,
  • fourth-zone hands with a very strong 5-card major (minimum ace king queen x x).

Some advice:
Open 2 clubs if you hold the number of tricks for game minus 1

Problem E2508 2 clubs With a magnificent third-zone one-suiter (about 18HCP), open 2 clubs strong undetermined hand. If you open 1 diamond then jump to 3 diamonds that would indicate a second-zone one-suiter (15-17HCP)
