Dans le cadre de ses activit\u00e9s professionnelles d’enseignant et d’arbitre au Bridge Club du Perreux, Pascal Ringuet commente r\u00e9guli\u00e8rement des donnes jou\u00e9es en Tournoi. Ces donnes comment\u00e9es sont envoy\u00e9es gracieusement \u00e0 tous les membres du Club.<\/p>\n

A quoi sert un Barrage ?<\/strong><\/p>\n

La donne N\u00b0 20 de la Ronde de France mardi dernier, 29 novembre, plus que mal trait\u00e9e, m\u00e9rite que l\u2019on s\u2019y int\u00e9resse pour 2 raisons\u00a0: Du fait de l\u2019ouverture de barrage en Ouest et de l\u2019interpr\u00e9tation de l\u2019ench\u00e8re de Sud suivant la hauteur \u00e0 laquelle lui reviennent les \u00a0ench\u00e8res\u2026 ! 12 Bonnes lev\u00e9es sont visibles sans effort, et pourtant, le \u00a0chelem n\u2019a \u00e9t\u00e9 appel\u00e9 que 30 fois sur environ 700 paires !<\/p>\n

Petit rappel des 4 jeux :<\/p>\n

\"donne20_ringuet_bbo\"
Donne N\u00b020<\/div><\/div>
\n1er cas :<\/strong> La s\u00e9quence devrait se d\u00e9rouler \u00e0 peu pr\u00e8s \u00a0ainsi :<\/p>\n

3\u2665 \u00a0 \u00a0 \u00a0 Passe \u00a0 \u00a04\u2665 \u00a0 \u00a04\u2660
\nPasse \u00a0 \u00a0 ?
\nEvidemment, \u00abdevrait\u00bb\u2026, car \u00e0 beaucoup de tables, nombreux joueurs ont oubli\u00e9s de PROLONGER le barrage !! Avec Z\u00e9ro lev\u00e9e de d\u00e9fense, il est imp\u00e9ratif de faire une action !\u2026sinon on ne voit pas trop \u00e0 quoi ces ouvertures peuvent servir !
\nLe probl\u00e8me, ici, est que Sud, pour d\u00e9barquer \u00e0 4\u2660, pourrait avoir bien moins de jeux et faire la m\u00eame ench\u00e8re avec un ou deux Rois \u00a0de moins\u2026voir QQ Piques\u00a0de moins\u2026On essaye de faire \u00a0au mieux dans cette position, et, les barrages sont l\u00e0 pour\u2026G\u00eaner !!
\nIl n\u2019emp\u00eache que la main de Nord m\u00e9rite un tour d\u2019ench\u00e8re \u00e0 mon humble avis\u2026 Tous les contr\u00f4les, deux AS et au moins une couleur exploitable valent bien un tour d\u2019ench\u00e8re. Le partenaire a quand m\u00eame d\u00e9barqu\u00e9 vuln\u00e9rable\u2026 !
\nPersonnellement, j\u2019aurais impos\u00e9 le chelem par \u20265SA pour r\u00e9cup\u00e9rer \u00e9ventuellement une \u00a0 mineure si Sud en poss\u00e8de une ! ( ex :ARxxx,Ax, xx, RVxx ) \u00a0Ici, Sud aurait donc conclu \u00e0 6\u2660 pour une note\u2026exag\u00e9r\u00e9e\u2026mais bien r\u00e9elle ! de 97,79% !!!<\/p>\n

2\u00e8me cas<\/strong> \u00a0 \u00a0Est s\u2019endort\u2026 et passe !!<\/p>\n

3\u2665 \u00a0 \u00a0 \u00a0 passe \u00a0 \u00a0passe!! \u00a0 4P
\nPasse \u00a0 \u00a0 ?<\/p>\n

Pour le coup, le r\u00e9veil \u00e0 4\u2660 s\u2019impose de lui-m\u00eame et montre bien ses ambitions de les gagner !! Dans cette position de r\u00e9veil, cette ench\u00e8re est \u00abatt\u00e9nu\u00e9e\u00bb et montre environ 7\/8 lev\u00e9es de jeux. Absolument parfait pour cette main ! Un bon vieux blackwood devrait permettre \u00e0 Nord de finir le travail ! En num\u00e9ro deux, la main ne vaudrait qu\u2019une intervention \u00e0 3\u2660\u20264\u2660 montrerait une top carte de plus (8 \u00bd \/10 lev\u00e9es de jeux). \u00a0Le bon vieil adage \u00ab on ne fait pas de barrage sur un barrage ! \u00bb, permet normalement ici de s\u2019y retrouver .
\nL\u2019empaillage de ce chelem laisse 60% au N\/S\u2026quand m\u00eame\u2026ce qui est plus que bien (trop peut \u00eatre\u2026)\u2026pay\u00e9 ! En conclusion, sans la prolongation du barrage, le chelem aurait d\u00fb (pu\u2026), \u00eatre appel\u00e9 \u00e0 de nombreuses tables ! Avec la prolongation du barrage, une certaine confiance dans le style du partenaire aurait d\u00fb faire reparler Nord ! Voil\u00e0 pour cette \u00ab passe d\u2019arme \u00bb entre barreurs et barr\u00e9s.Bonne semaine \u00e0 tous et \u00e0 mardi prochain.
\nPascal.
\nPS : Pour les AS de la d\u00e9fense, \u00e0 7\u2665X -5 !, on sauve 30 centimes !, 1400 contre 1430\u2026pour \u00a0exactement la m\u00eame\u2026note \u2026<\/p>\n

Bonne soir\u00e9e, Pascal Ringuet<\/p>\n
