Dave Neuman and I recently played in the Santa Rosa Sectional. Board 7 from the morning session was a solid victory for a big club system combined with losing trick count.
Dave and I play Precision. An opening bid of 1 Club shows a hand with at least 16 points if unbalanced or 17 if balanced. Dave opened 1 Club with
The next hand came in with 2 Diamonds. I held
I bid 2 Hearts, game forcing with 5 or more hearts. Dave jumped to 4 Hearts, showing a minimum big club bid with heart support. Now I saw a 5-loser hand opposite a big club opening, which is usually a 6-loser or less hand. Eureka! No more than 11 combined losers, good fit, void in opponent's suit. This added up to a likely slam, so I just bid 6 Hearts. As you can see, it made easily. All I needed was to draw trumps and not lose a trick to the jack. 12 easy tricks, just lose a spade. For this result we got 16 matchpoints with 17 top.
