EAST for the Jack
#1 Win 4 tricks
This is back to the play on same 9.. lead low and insert the TEN, or you can lead towards the A8xxx and insert the eight.
#1 Win 4 tricks
A low to the ten... If suit is 3-3 you lose 2. If it is 4-2, you got to hope WEST has doubleton Kx, Qx, or Jx, or EAST has KQ, KJ or QJ doubleleton.. But the pickup is when WEST has Hx doubleton
#1 Win 4 tricks
How many tricks do you need? If you need six, you have to play Queen and hope to catch RHO with Kx doubleton. IF you need only five, it is better to play the ACE and lead up to the QJ... (sort of similar to QJxx opposite Axxx)
#1 Win 4 tricks
Play small from dummy first, then ACE-QUEEN-JACK in future
#1 Win 4 tricks
Play low the first time. If neither KQof J is played, play low the second time. IF someone wins K, Q, or J on first round, lead out the ACE on the second round.
#1 Win 4 tricks
Leading the QUEEN and let it ride if not covered and lead the TEN and let it ride then in both cases repeat the finesse both have 87% (76%... the 87% was a frame shift typo) chance of wining two tricks... but, leading the QUEEN first is best.. because if WEST has singleton JACK you can win three tricks. There is no way to win three tricks if WEST has the singlton King.... so that "EXTRA" chance makes QUEEN the matchpoint play.
A hidden remark for intermediate+ players: There is a 3rd way to play it, that has technically almost the same chances for 2 tricks, but allows defenders go wrong: Lead low from hand to the 10, finessing against the J. If that loses, lead the queen, playing low if not covered, thus finessing against the king. This only loses if RHO has the J, and LHO has the king. But when LHO has Kx(xx), he may well go wrong and play the king on the first round.
