Now you see,our game is cool ,but a pity GIB don't respond with 5 hcp.who know the exact reason?

[Antrax]

GIB saw you complained when it responded with 4 HCP, so now it's afraid.

[ahydra]

Do you really want to be in game here? I assume that'd be 4S, which looks horrible if spades don't break and you get forced in clubs.

You still need to remember that GIB replies with 6 or more total points, not necessarily any number of HCP. North has only 5 total points on this hand, because you don't count for both ♠J and ♠doubleton.

what's 8421? how many total points is one Ace plus one Jack in 8421?

8421 means ace=8, king=4, queen=2, jack=1. So the answer is nine.

helene_t's answer is 9 count,however you said GIB replies with 6 plus total points,why pass? You seem to be very contradiction.

The answer is the same as when you asked that question last month.

Robot answered 3♣ to show "3+8421hcp in C",I don't know its exact meanings,who can tell me? thanks.

A = 8, K = 4, Q = 2, J = 1.

So 3+ means at least QJ in the suit.

As I understand it, this is how GIB "knows" to evaluate honor strength -- e.g. when cuebidding it doesn't think of Ace vs. no Ace in a suit, it thinks of 8+ (Ace) or 7- (no ace).

No. Please pay attention. GIB has several different ways of counting:

• High card points (HCP). A=4, K=3, Q=2, J=1. Just like every beginner book tells you.
  
• Total points. HCP + distribution (1 for doubleton, 2 for singleton, 3 for void, without double-counting for shortness with honors). This is what GIB usually uses (except for NT bids) to determine whether to bid and how high.
  
• 8421 points. A=8, K=4, Q=2, J=1, and always in conjunction with a specific suit. This is used for cue-bidding sequences, so you know what honors GIB has in which suits.
  
• Relay points. A=3, K=2, Q=1, J=1. Also generally used in slam-seeking auctions, but not really predictably.

Editted to include relay points, which I originally omitted.

8421 points and total points are not the same thing.

[1eyedjack]

8421 points are used for one purpose and one purpose only: to describe suit quality of a single specified suit.

And none of the other three evaluation measurements are suit-specific.
