English 59 The 52nd International Tel Aviv Festival (3) Ram Soffer One of the more entertaining Israeli pairs, and members of the Israeli Senior team for the 2018 European championship in Ostend are Micha Mark – Yuval Lubinski. The following two deals have one thing in common: a daring bid of seven spades by Yuval Lubinski. The first one appeared during the first round of the IMP (Butler) Pairs: Board 6. Dealer East, Vul E/W ♠ ♥ ♦ ♣ AQJ85 K4 AKQJT8 - ♠ ♥ ♦ ♣ 942 QJ987 53 T98 ♠ ♥ ♦ ♣ 6 T532 9642 AK62 ♠ ♥ ♦ ♣ KT73 A6 7 QJ7543 West North East South Lubinski Mark Pass 1♣ Pass 1♠ Pass 2♠ Pass 4 ♦ Pass 4♠ Pass 4NT Pass 5 ♥ Pass 6NT Dbl Pass Pass 7♠ All Pass Once South decides to open his ten-count, North starts thinking about a grand slam.
