Herman's brilliant safety play

With no-one vulnerable, I hold :

A96
KQ8653
52
K2

and the bidding starts on my left :

1D    1S    pass

so I start with what I suppose to be a slightly forcing 2 hearts :

1D    1S   pass   2H
pass  2NT  pass

I correctly assume that 3 spades now indicates to partner to choose a game contract, and she does :

1D    1S   pass   2H
pass  2NT  pass   3S
pass  4H   all pass

Dummy comes down :

KT843
A74
QJ3
AT

A96
KQ8653
52
K2

Left hander leads King and Ace of diamond (right the 8 and the 6, indicating two) and returns another diamond, ruffed with the nine.

Overruffing ?  No certainly not. I throw a spade and claim the rest.  Elementary safety play, you could say, but the majority in our club apparently did not find it. So I had an almost absolute ZERO.

Why ? .... Spades were 0-5, and RHO did not need my claim to find that return.

And of course hearts were 2-2, so the simple overruff did work.

I calculated the chances : knowing six diamonds on the left and 2 diamonds and a heart on the right, there are 19.448 possible distributions for the remaining 17 cards. In 792 cases of those, spades are 0-5.
So the safety play works in 95.93% of the cases.

Of these, 10 cases have spades 3-1 and 15 have them 0-4, so the normal play would not work either, so in fact I was in a 3.94% event of bad luck.

That's me !

The full deal :
