Here's a hand from a recent team game. Playing whatever methods you prefer, what would be your auction? Can you reach the best contract?
My auction with Elianna (playing sayc with extras):
1♠ - 2♣
2♥ - 2♠
3♦ - 3NT
Here 2♣ is natural (4+♣), forcing one round; 2♠ is nonforcing (often doubleton); 3♦ shows a game force without clear direction; 3NT guarantees a diamond stop.
At the other table (playing 2/1):
1♠ - 1NT
2♥ - 2♠
Here 1NT was forcing and 2♠ is a (somewhat heavy) simple preference.
We lost some imps on the board, as the opponents lead a diamond and the club king was off (so they took 2 diams, 2 hearts, and 1 club with good cashout skills). However, 5♣ seems excellent on this board (much higher percentage than 3NT) and 4♠ is also good.
