2.1 First to Announce

2.1.1 Strength when announcing first

The main thing to consider when deciding whether to announce or not is your own hand. Strength is best estimated by the average points expected to be won.

This value only for one Ace

From this is determined th minimum requirements for announcing first: RE: >= 75 points and CONTRA: >= 85 Augen.

The decision is reached by multiplying the possible points by the likelihood of taking them (see Tab. 2).

Let's look at some example hand that will make this clear.:


Hand 1
: Q Q Q JJ Ace K Ace Ace AceK 9
(your play: Ace goes around with 25 points)
possible tricks:
1) Q Q = 3/4 x 22,5 ~ 17
2) Ace = 3/4 x (11 + 3/6 x (50 - 22)) ~ 19 (exact value when announcing)
3) Trump 2nd. -lead = 1/3 x (11 + 3/4 x 25) ~ 15, since 25 were taken in the first trick. S = 25 + 17 + 19 + 15 = 76 = RE.

Hand 2: Q Q J J J J J 10 K 9 K 9
possible tricks:
1) Q = 3/4 x 17,5 ~ 13
2) Trump 1st-lead: 3/4 x (10 + 15) ~ 19
3) Trump 2nd /-Lead: 1/2 x (4 + 17,5) + 1/2 x (2 + 17,5) = 20,5 S = 13 + 19 + 20,5 = 52,5 = no RE. The expected value will certainly be somewhat higher depending on the low cards in/ and the length of the trump holding.

In any case, the first announcement should be make at the last possible point.

In addition to the announcement timings described above, the Essener System also provides for some announcements prior to the play of the first card.

The player indicates with such timing that s/he definitively can undertake a game. This requires possessing a double-10 (in Position 2 also). The announcement characterizes a stong RE-hand. This doesn't necessarily mean that Aces are held. The partner who follows is not necessarily obligated to lead trump.

This announcement timing is not used by the KONTRA-player since the double-10 holding is not useful for them. You know that the partner of a strong Contra player has no particular trump control which is not the case with the RE player.

 

2.1.2 90-Requests

A bidding opportunity occurs when a player confronts tha lead of a card by waiting a few seconds before playing a card to the trick. A player does this in order to give his/her partner the chance to make another announcement. A requirement for this action is a strong hand and a real advantage for the side when the signal is picked up by the partner.

Examples of "real" advantage:

We distinguish between forced and invited Requests. A forced request can be made only when the hand is so strong that even a weak hand held by the partner does not offset the benefit (for example.: Q Q J 10 Ace K K 10 K 9 K 9, RequestAs). The requester must also deal with the possibility of an unusual card distribution in this case as well. . The requested parter is obligated to respond (no answer = no Partner).

With an invited request, the partner with poor cards may simply not respond. In both cases, the requester has accepted the responsibility for the announcement of the partner. The partner who receives the request simply must trust the request of the one making it.

1) Request just before playing a card and then a pause.

The request is forced
, means that a partner who can probably take the trick (with an Ace or trump) is obligated to announce No-90. The following is an example:.

Hand 1: 10 Q Q Q Q J J Ace 10 9 10 9
Request with playedAce or entry with (throwing off 10 is possible).

Hand 2: 10 Q Q Q J JJ J K K Ace 9
Request with played Ace or entry with.



2) Announcement to play made by another, then a pause before playing one's own card.

The request is simply invited
,

Example hands:
Hand 1: 10 Q Q Q J J Ace 10 9 10 As 9
This is equivalent with the first Hand in 1) with the exchange of Q for Ace. This is a poorer trump holding and an additional side suit holding.

Hand 2: 10 Q Q Q J J J J K K Ace 9
This is the same as the second forced hand with the exchange of Q for Q. This is a poorer trump holding and a change in partnership.

Hand 3: Q Q Q Q J J J J J Ace Ace 10
This relates to the third forced hand. In position 3, only invited requests forAce should be made.



2.1.3 Conventional Leads

I) 10-Lead conventions:

The lead of a 10 (up to the last possible point) shows the holder of a Q and aQ (rarely alsoQ and double-Q). There are numerous cases depending on when the announcement is made.

We distinguish between three cases:


1. Announcement with the play of one's first card and the play of 10 no later than the third trick.

Meaning
: My hand is so strong that merely the play of 10 by my partner will hold the other side to under 90. The partner should immediately play 10 and announce No-90 wenn holding the other 10 independent of the strength of his/her hand.

Hand 1: 10 QQ Q J J J J Ace K K Ace
Hand 2: 10 Q Q Q Q J J Ace K Ace 9 Ace.


2. Play of the10 to the first or second trick without announcement.

Meaning
: I'm simply strong in trump (6-8 [usually 7] Trump headed by 10 Q Q ), but I have some side cards to contribute to tricks my partner wins. Examples:

Hand 1: 10 Q Q J J J K K 9 Ace 10 9
Hand 2: 10 Q QQ Q Ace K 10 10 9 K K
Hand 2 should make no announcement, if is trumped on the first trick.

The partner with average holdings and 10 should immediately announce RE.

3. Play of the10 to the first or second trick with the announcement of (RE) at the last possible moment.

Meaning:I'm medium strong in trump and have some smear cards, but am uncertain whether they will go through.

Examples:
Hand 1: 10 Q Q Q Q J J 10 Ace 9 As 9 (8 good trump; 2nd Ace to follow)
Hand 2: 10 Q Q Q J J J As 10 K K K (9 Trump)
Hand 3: 10 Q Q J J J K 10 K K Ace 9 (Trump a black suit)

 

II) D/D-Play Conventions:

Playing D/Q declares a RE player with double-10. Similar to the10-Play Convention the timing of announcements is important.

1) Announcement with the play of the first card and the play of D/D by the third trick.

Meaning: The player holds a strong RE-hand (see also Section. 2.1.1) and with a little help from the partner (such as Q, two smeared Aces) the No-90 announcement can be made.

Examples:
Hand 1
: 10 10 Q Q Q J J J K K K 9

Hand 2: 10 10 Q Q Q J J K Ace K Ace Ace



2) Play of Q/Q during the first two tricks without announcement.

Meaning: The player is short in trump (5-6, rarely a weak 7) without additional values, that the partner will not recognize.

Examples:
Hand 1: 10 10 Q J J K 10 K Ace 9 9 9

Hand 2: 10 10 Q J J 10 9 K 9 Ace 10 K


3) Play ofQ/Q to the first or second trick and announcement at the last possible time.

Meaning: The player holds a hand with double-10 (different from 2) additional point cards.

Examples:
Hand 1: 10 10 Q Q B B Ace Ace Ace 9 Ace 9

Hand 2: 10 10 Q Q Q K K K 9 Ace K 9

Hand 3: 10 10 Q J J J K 9 10 K 9
