The play:

6 led (2nd from 3 or 4 small, top of doubleton), E takes the AQ W following with the 2 then plays a diamond.

Suggestions ?

Due to the risk of ruff I'd go with A, cash AK and make with or without an over trick depending on finesse.
If Q did not drop, then I need finesse anyway since i already lost 2 tricks and will lose a spade.

The reason I chose this line is, I expect E to hold doubleton club. With 4 he could give his pd a ruff, with 3 card clubs he would not have cashed the A before he played
Most important thing in my line is that E is coming from pass and we already saw him with AQ . My line loses when E also has K+K which makes him to have passed with 12 hcp.

"Well to be perfectly honest, in my humble opinion, of course without offending anyone who thinks differently from my point of view, but also by looking into this matter in a different perspective and without being condemning of one's view's and by trying to make it objectified, and by considering each and every one's valid opinion, I honestly believe that I completely forgot what I was going to say."

I'm with Mr. Ace on this one.

The basic lines are either finesse the queen or use Mr. Ace's line.

If you finesse it's about a 55% chance if you believe East's are doubleton or 50% if Clubs break 3-3.

If you play A and AK, you always make anytime the Q falls. That comes out to be about 40% of 3-2 breaks (about 27%), 20% of the 4-1 break (another 6%). That totals up to about 33%. In addition, you also make if the Q doesn't fall and the finesse works with 4-3 (about 21%), with 5-2 if spades are 3-2 (about 7%) plus some additional amount that the long trumps are in the hand with the long . That comes out to about a 61-62% chance of success.

You have a 9 card spade fit (6-3) so working out how the remaining 5 split is not the prime concern.

I was with Mr Ace too, as was the declarer at the other table, unfortunately partner wasn't, and he was at the wheel.

Thanks Cyberyeti. Getting old, I'm looking at a 9 card fit and seeing 8. Grrrr.

So you're looking at success 40% of the time when break 2-2 plus 25% of the time that they break 3-1 (about 12.5%) when the Q falls. In addition, you also have success when when the Q doesn't fall -- if break 4-3 with the finesse working (about 15%), break 5-2 with the finesse on and break 3-1, or if break 5-2 with 4 in the long hand. That's probably something like a 75-80% chance of success.
