Hi
Please could someone explain the double dummy notation in the hand history, or guide me to where I might find it.
Thanks in anticipation :)

At all times, for all cards, assuming everyone can see all cards and play perfectly:
  • a number in red means the contract is going down that many tricks if this card is played now;
  • a number in green means the contract is making with that many overtricks, if this card is played now;
  • an equals sign [=] in green is equivalent to "green zero", i.e. the contract is making exactly, if this card is played now. [=] is probably used instead of [0] because traditionally 2H= means "2 hearts, making exactly" (so everyone knows what it means), and because [0] "looks like" a bad thing (could be misinterpreted as "making no more tricks" or "getting a zero" instead of "making with zero overtricks").

And (not intuitive, at least for me) Red is always bad for the declarer and so on, even when you were a defender (and it is good for you).
