Rather than style, might I recommend a historic tour of different eras and playing styles. Start with *good* annotated game books in chronologically ascending order. If your rating here is an indication of your current playing strength, these books will also provide you some solid foundations.
Examples of such a reading progression would be starting with Morphy, Anderrsen, leading up to the mid-20th century with Capa, Marshall, Tal, Karpov, Fischer etc.
Karpov might be an interesting guy to really follow if you love solid, defensive games.
Until you really break the Class B/A barrier, I'd avoid books / following Masters post-1970s as the nuances of their play are way more complicated and the "styles" aren't as singular and easy to pick out.
I was wondering if anyone has any idea how to look up GM's and their playing style? For example which GM's were agressive,which one were more defensive etc. I believe I am more of a defensive type of player, albeit a low rated one. I want to start looking at their games. Any help would be appreciated. BTW I am doing 50 TT problems a day. And studying Chess Mentor also, focusing on Tactics right now.
