Scoring: IMP
The bidding just simple, south opening with one di, north 2NT, south 3NT. Opponents passing. The lead dia2, played small, nine, ace. The problem is obvious - how to avoid loosing one dia and four or five spade tricks before taking nine in dia, hearts and clubs. Played dia back, jack took the trick. Now...played spade 9, covered with ten, "ducked". Back king of spades...mission impossible became possible.
After the game, was just looking to the way, the same board was played at the other tables. The game was made at half of tables, mostly simple mistakes of the defenders, but one approach was even much more interesting than mine. After the same bidding, the declarer (north) got small H lead and ducked the H ten! "Obvious" H back was taken with ace, dia K was given to the opponents and they "cleared" H suit. Game made!
Can experts give me some logical explanation, which way real expert can avoid misdefensing the game in the first and second case demonstrated? Thank you very much.
