Deal analyser

Double dummy is how a hand plays when every player can see all four hands: the most tricks declarer can take against the best defence. The table gives that number for each of the four seats as declarer, in notrump and in each suit, so you can see at a glance which contracts make and which go down.

Par is the contract both sides would reach if each bid as high as was worth it and no higher — the score neither side can improve on by bidding on or by sacrificing. It depends on who is vulnerable, so you can change the vulnerability after the deal is in and watch par move.

Paste a deal in either of the formats bridge programs write. PBN is a deal string such as N:AKQ.JT9.876.5432 … — four hands, North first unless the letter says otherwise, suits in the order spades, hearts, diamonds, clubs, and a ten written as T — or a whole game copied from a PBN file, whose dealer and vulnerability are read too. LIN is the format Bridge Base Online uses: paste the string with its md| field, or the hand viewer link itself.

Nothing is saved. The deal travels in the link, so anyone you send it to sees the same hands and the same table.
