The auction was 1♣-P-1♥-1♠-2♣-P-P-2♠-P-P-2NT-all pass.
Our expresseed defensive agreements: Reverse Smith Echo (small encourages), 4th Best against NT, with attitude implicit (second highest or highest from several small), standard count/attitude, Rusinow in own suit (and generally against NT), King lead (power) asks for honor or count.
My lead was the spade 3 (sixth best). Question #1: If you agree to lead fourth best and instead lead an obvious sixth best (known long suit), what is this? My personal view was that a sixth-best lead "emphasizes attitude," thereby showing great "body" and asking partner for honor or count. It could also logically be suit preference (here, diamonds) or count (fourth best implying a five-card suit -- no sixth card to lead).
On the small spade lead, everyone followed as Declarer won the Ace, partner playing the 9.
Declarer at trick two sent a club toward his King in hand, which I won, partner playing the 9. The nine could be stiff, or negative attitude from 94, or positive from 109 (Reverse Smith).
Q2: What next? I assumed that Declarer had something like Kx or K10x of clubs, Kxxx/Qxxx of hearts, K(J)x(x) of spades, and, therefore, no diamond Jack. As a hedge, though, my lead was the diamond King, partner encouraging diamonds. (Is this an "obvious shift" situation, and, if so, is the obvious switch spades, or hearts???)
Partner encouraged. So, I cashed the second high diamond, saw a very low diamond, and switched to hearts. This allowed a TON of tricks to be taken (-150), when we could have set this contract several tricks.
Partner held Jxx of spades, Jxxx of diamonds, and 109 of clubs, Qxxx of hearts, possibly with the 10 (cannot remember -- it was moot).
The argument. Partner felt that the club 9 was clear, as Declarer would bid 2NT immediately with K10x of clubs. I disagreed, feeling that 2NT on a 10-count would be sick. Partner felt that this did not call for the spade Jack to be played at trick one, I disagreed. Partner felt that continuing diamonds was sick, notwithstanding the encouragement; I felt that discouragement of diamonds was the only opportunity for clarifying the ambiguous Smith Echo problem. Partner felt that setting up his diamond Jack was a fruitless maneuver; I felt that it decreased the risk of a successful club finesse if Declarer held K10x. Partner felt that Declarer was "marked" for NOT having the spade Jack at trick one; I felt that rising with the Ace was the best action with KJx(x)-Kxxx-xx(x)-K10(x) to reduce the risk of a diamond switch; partner felt that only I and Garozzo might make that play (me because I am twisted).
