Hi,

I haven't played competitive chess for about 10 years now. I am reasonably strong player as for amateur (2300 ELO).
I played d4 most of my life but I don't really like it anymore (mainly because I have trouble choosing all the awesome options black have after 1.d4 and I am very comfortable playing vs it). I have some time and willingness to try to improve a bit again and I would like to learn 1.e4 openings.
I need good resources for learning main/semi mani lines after 1.e4. I am generally happy with how the positions of main lines of petroff/spanish/most sicilians look so I am not going to avoid those. What are the best resources to learn ideas/modern way of playing those openings ? As to specific moves I can look those up in countless of computer books so those are not that important as getting general idea for me.
It seems that this book: http://nic.net4u.nl/Sicilian_Attacks-p-946.html is what I am looking for sicilians.
I would appreciate if you could reccomend some sources for other openings.
