I just make an error which really fooled me.


Perhaps this is really more a counting error but still I just wanted to point it out.



AJxx in dummy

I have Kxx


declarer lead small from dummy at suit contract and I played K


now declarer with xx can finesse and throw loser from side suit.


I will remember this one teaching moment.

You were not necessarily wrong, declarer might have had Qx and avoid you taking the setting trick if you duck (he still gets 3 tricks by ruffing your K out but doesn't lose one). It's a decision you need to take in the context of the whole hand.

With qx opp Ajxx why wouldn't declarer just finesse

[bgm]

It looks like partner fail to lead the interior sequence from Q109x

As Cyber said it depends on the full deal. Let me give you an example; You have another suit Axx in hand xxx in dummy and A is the only entry to hand. If you use it, and lose the finesse you give a trick in the finesse suit and 2 tricks in the suit that you knocked down you entry. Instead you just voluntarily give their K by playing to Qx and lose still 1 trick in that suit but will give no more than 1 trick in the Axx vs xxx suit. Note that even if your finesse was working you would still lose 2 tricks in that side suit. Even if you did not have an entry problem you may play towards the Q because it loses nothing (unless K was stiff onside) but may gain when the defender does the opposite of what Mike777 did and not play the K, as Cyber said you still make 3 tricks in that suit without losing any and discarding 1 from the side suit.

As defender you may have learned a lesson, but declarer has also learned the power of the closed hand.

I suppose you might say, AJxx is not something declarer will normally lead away from when you hold Kxx. Therefore, assuming declarer isn't a loony (a dangerous assumption!), then he/she is up to something. It's up to you to figure out what.
