Did you consider Smerdon's Scandinavian repertoire book (2...Nf6)?
I have the book and began to play it without learning more than 20% of he repertoire. But this is definitively not the kind of defence you should play without working through the whole book. The defence doesn’t have a great reputation among strong players. I usually got crushed playing it against much weaker players.
Indeed. As I having been playing this game for awhile (like 30+ years) I too bounced around between DKP openings & Sicilians (Namely, the Najdorf!) and I'm also QP player as white. Indeed2 it's not a knock against you if you're taking time to find out what's best for you. You have a lifetime ahead of you soo dont be too concerned. The important thing is using that time to figure it out in practical play rather than always reading books. Playin's the thing, to me. Yes, I'm also a book player but I built my repertoire from the ups n downs of actual real time experience. Forget the wins and losses. Nonetheless, I play the CK on a practical basis and save my Sicilian play for special opponents (even though I played it exclusively for 6years OTB) online games. Play daily games more but get in some blitz. Other than that, have fun my friend! Best wishes😉
