I played against extotionist strategy and I guess I got lucky because I'm leading (my score - 1) : (his score - 1) = 2:1 and won't change into 1:3 as advertised because from this step I will always defect.

From the description of the extortionist strategy in the demo: "The only way you can avoid being taken advantage of is to resign yourself to the meagre rewards of mutual defection, and to defect on every turn."
So: yes, indeed you can do that, but then your long-run score will be rotten because it will look like a vast succession of (D,D) plays, 1 point each. If you let the Extortionist extort you, you will get substantially more points.
"The only way you can avoid being taken advantage of is to resign yourself to the meagre rewards of mutual defection, and to defect on every turn. If you do anything else then I will take advantage of your cooperation and I will do three times better than you, in the sense that – on average over the long run – (my score minus 1) will be thrice (your score minus 1)."
I was refering to that. I did something else than dfecting all the time and got better result than 1:3 but that's ok since 1:3 is average over all strategies.
