IMPs?
♠3 = ?
Assuming IMPs and that the ♠3 is "4th best", I'll continue spades at trick 2!!
The idea is that if opps now cash their spade tricks (hopefully only four!), I'll be in a better position to guess which finesse is working, if any. Not only because it's a priori better to finesse through the player with only four spades, but also because I get a chance to see
* that player's discard on the last spade
* exactly what spade suit LHO led from (does it suggest an awkward lead?)
* what the player with the fifth spade will shift to
.
For example, if the lead seems to have been awkward, then other leads probably looked at least as awkward, which to me is a strong indication that the heart finesse isn't working and that I should I try to play the club suit without a loser instead. But, depending on what has happened after six tricks, I might do better by cashing the ♥A first (in case the ♥K drops) before taking the (first) club finesse!
Enough details for now, I think.
I think the idea of exiting a spade at trick two is a terrible idea.
They will usually untangle the suit, and the suit appears to be 5=4 or 4=5.
You can pitch one club from dummy, and maybe a heart, so you pitch one diamond. You can’t pitch hearts from hand, since you need four heart tricks if you decide not to take the club hook (of course, dropping the club Queen solves all problems but we have to plan the play for when it doesn’t drop) so you pitch three diamonds (if you are thinking of a club hook, you probably want to be able to pick up Qxxx).
Now, if LHO wins the fourth spade then, against non expert defenders, you might have some clue as to what’s going on, although after all the diamond pitches, LHO can usually play a diamond safely and you’re pretty much back to the trick one position. The real problem with your line is that east may win the last spade. Now a good defender plays a heart regardless of his holding. This makes you commit right now…heart hook or play on clubs
Note that helene’s line, which I endorse, let’s you try to drop the club Queen….if it drops, run the clubs for ten easy tricks, with possibilities for more, depending on how they discard…and if it doesn’t drop, take the heart finesse. The club Queen will drop quite often…20% of the 4-1 breaks and 40% of the 3=2 breaks so almost one third of the time. When it doesn’t drop, the heart hook is roughly 50% (the exact figure depends on how clubs and spades lie). So the combo play of clubs then hearts will win about 2/3 of the time…nearly one third for clubs and roughly 50% of the remaining times. On your line, if east wins the last spade, you’re committed to choosing between two 50% lines….heart hook or club hook.
Oh…and expert defenders might even switch to a heart even earlier. If I were east and held QJxx Kxx xxx Qxx, I’d at least consider winning the second spade and playing a heart right now…usually my highest spot to simulate xxx(x). After all, when declarer exits a spade, I know he doesn’t have a clear path to 9 tricks and the tactic of forcing a premature decision is well known to any expert player.
