Notes

About

Intro

This is an intereactive bridge hand evaluator.

Example

Enter your hand, click "evaluate," and it applies a number of evaluators to the hand.

Why doesn't it always let me evaluate?
  • The button will usually tell you why it is disabled. Additionally, if any holding is invalid, that holding's field will be marked in red.
  • Because this is currently a work in progress, where the code is changing, you might have to do a full reload. Hold down the shift key and hit the reload button.

To Do

  • Implement more evaluators (specifically, "Binky.")
  • Improve look-and-feel.
  • Test in more browsers. The only mobile device I have is iOS, so if you use an Android, let me know if it works.
  • Possibly let user select evaluators.

Evaluators

CCCC
The Kaplan-and-Rubens evaluator.
HCP
The standard high card points sometimes called the Milton Work point count, where Ace=4, King=3, Queen=2, Jack=1.
Fifths
The Fifths evaluator is an evaluator which adjusts standard HCP slightly, removing one fifth from the value of kings and queens and adding two fifths for tens. It might or might not work better for determining whether to bid 3NT or not.
BUM-RAP
Alex Martelli's adjustment to work point count, which seems good for suit contracts. A=4.5, K=3, Q=1.5, J=0.75, T=0.25.
Bissell
Closely related to losing trick count, Bissell's evaluation dates from 1936. (If you subtract Bissell from 39 and divide by three, you get a rough losing trick count.)
