Hilver

In Hilversumse Klaveren (a New Big Club bidding system) we bid 2♣. 2♣ = 1. 10+ HCP and exactly a 4-card M and a 5+-card m; this may include a GF 4M-5+m, or 2. long clubs and GF, or 3. a GF 3=3=3=4♣ With a minimum (11-13 HCP) OH rebids 2♦. Any other rebid - 2♥ to 3♦ - is 14-15 HCP. There are several relaybids for AH to describe his holding. If You do read some Dutch, take a look at page 59 of the systembook on http://home.tiscali.nl/hilver/hk.htm. In Hilversumse Klaveren (HK) an openingbid of 1♦ = 10-15 HCP, no 5-card M or 6+-card ♣.

Isn't this a Brown Sticker Convention? Brown sticker is a category of contract bridge conventional agreements defined by the World Bridge Federation (WBF). Brown sticker conventions are considered, by some, to be difficult to defend against, and thus are only permitted at the highest levels of tournament play in most locations. Only highly unusual methods (HUMs) have a higher classification. The official definition can be found on the WBF website.[1] A short summary would be that a convention qualifies for a brown sticker if it fulfills any of the following criteria: 1. An opening bid of 2♣ through 3♠ may be weak and does not promise a known suit. 2. An overcall of a natural opening at the one level does not promise 4 cards in a known suit. 3. A weak two-suited bid where one of the suits by definition may be only 3 cards or shorter. It is used for protection of psychic bids, or systemically required psyches. Notable exceptions are the Multi 2 diamonds (due to its popularity), a natural 1NT overcall, and cue bids on strong hands to force partner. The bottom line is, that if a bid is weak (or potentially weak having multiple options) and does not promise 4 cards in a defined suit (when weak) then it is likely to have a brown sticker. Jan

In HK: 1♣ - 2♣ = 6+ card ♥ 0-7 HCP 1♣ - 3♦ = 7+ card ♥ with 5-7 HCP, most of the points in ♥ 1♣ - 4♣ = 7+-card ♥ with at least AKQ, no outside strength For bidding in this way, North should hold at least 6 good hearts and outside strength. For he is willing to play in hearts opposite a singleton heart. South knows North has at least 6 hearts with A, K and Q and AK in spades. If North holds a 3-card spades, then he possibly can ruff the third spade in South. North has at utmost 5 cards in the minors, there is a chance of establishing one of South's minors. And of course there is always the chance of a diamond finesse. HK is not a symmetric relay system, so South will not be quite sure about 13 tricks. But there are a lot of chances. Jan

With 5 hearts and 6 diamonds we prefer bidding hearts first. In HK we do not have a specific bid for a holding You mentioned. Our priority is always in the majors. If You hold for example: ♠ - ♥ K Q J x x ♦ K Q J x x x ♣ x x The bidding then might be: 1♣ - 1♦ 1♠ - 2♥ 2♠ - 3♦ 3♠ - 4♦ Explanation: 1♦ = relay 2♥ = GF, 5+ ♥ 3♦ = 4+ ♦ 4♦ = 5+ ♦ Jan

Hilversumse Klaveren (HK) North will pass, so the auction will be: pass - 1♣ 1♦ - 1♠ 2♦ - 2♠ 3♥ - 3♠ 4♠ Explanation: 1♣ = 16+ (Not a balanced 16-20) 1♦ = relay, denying several weak one or two suited hands with 0-7 HCP 1♠ = 16+, 5+card ♠, unbalanced, non forcing 2♦ = GF, 5+-card ♦ 2♠ = 6+-card ♠, not a 4-card ♥, may have support in ♦ 3♥ = stopper in ♥, not a stopper in ♣ 3♠ = not a stopper in ♣ 4♠ = well let's play in 4♠ Jan

If the cue is the king of clubs, it will be worthless. But there will not be a lot of losers in spades. Also in diamonds there will not be a lot of losers. So, no problem for South to use RKC. South can afford to play in 5♥. If North has only one keycard them he will sign off in 5♥, if two then 6♥ Jan

No, East did already win the first trick by playing the King of clubs. West playing the ♣K indicates West holding the Queen of clubs. Jan

The lead of tthe deuce of clubs indicates an honnour. Jan
