In contract bridge, various bidding systems have been devised to enable partners to describe their hands so that they may reach the optimum contract.Key to this process is that players evaluate and re-evaluate the trick-taking potential of their hands as the auction proceeds and additional information about partner's hand and the opponent's hands becomes available.
Zar Points (ZP) is a statistically derived method for evaluating contract bridge hands developed by Zar Petkov. The statistical research Petkov conducted in the areas of hand evaluation and bidding is useful to bridge players, regardless of their bidding or hand evaluation system.
A hand pattern denotes the distribution of the thirteen cards in a hand over the four suits. In total 39 hand patterns are possible, but only 13 of them have an a priori probability exceeding 1%. The most likely pattern is the 4-4-3-2 pattern consisting of two four-card suits, a three-card suit and a doubleton.

In the card game contract bridge, the Losing-Trick Count (LTC) is a method of hand evaluation that is generally only considered suitable to be used in situations where a trump suit has been established and when shape and fit are more significant than high card points (HCP) in determining the optimum level of the contract.
In contract bridge, Bergen raises are conventional treatments of responses to a major suit opening in a five-card major system. [1] Developed by Marty Bergen and first published in April 1982, [2] Bergen raises are based on the Law of total tricks, a hand evaluation concept which states that with a combined nine trumps in the partnership one should compete to at least the three-level ...
EHAA (Every Hand An Adventure) is a highly natural bidding system in contract bridge characterized by four-card majors, sound opening bids, undisciplined weak two-bids in all four suits and a mini notrump, usually of 10–12 high card points. [1]
