Here's the full hand. It's not that interesting, posted in the wrong forum.
What I have found interesting is, after being unable to initially post the hand here I posted on the other site and that led me to some articles on preempts
written by Andrew Gumperz. Andrew says
"The Rule of 2and 3 may be good enough for beginners, but it is a blunt instrument for aspiring tournament players. The rule focuses on one factor--keeping numbers smaller than the value of an opposing game, while ignoring more important considerations. If you follow the rule carefully, you will be taking risks that are too large in some situations, while not taking enough risks in others. To develop an expert understanding of preemption, you must look much deeper"
.and goes into great details, of course written with a focus on IMPs.

♦10. making 5
The vul. in the orig. was red vs. green, now it got changed to red vs. red.
The rule 2 and 3 does not take into the account the vul of the opponents, in contrast to the 2-3-4 rule, which advocates 2S,
it is not even close, I miscounted.
If you follow the rule of 2-3-4, responder has 3 sure tricks, and the ruffing value will generate 1-2 add. tricks, this means
you are unlikely to make 12 tricks and due to this you should simply raise to 4S and let it be, the preempt at equal vul.
promised 6 tricks, you have 4-5, the side king is not there, ..., maybe KT... is possible, but unlikely.
The advantage of 3S with the original hand is, it is the mainstream bid, and you are protected by their fear, that 3SX may make,
and just a reminder 4SX will usually cost more than their small slam, it is 1100, the small slam is less.
