punter,i dont know what level u reach in your yougner years but i did pretty well b4
....
if u read pawn structure chess,then you ll never need an opening chess book(since all the variation u learn in any "regular opening chess book" library sell change each 6 month, and can even be obsolete...),as for tactics,yes it s usefull but in reasses your chess is a most...and any book they suggest is probably almost the best there is(tactics included).
collection of good player is worthless if u dont even have an idea why they play any move if u dont have a position concept in chess(wich my system offers..)
anyway OP,u have suggestion u choose
...
and one of the biggest similarities with chess and poker......position,position,position is very important!!!!
proof of it...any good player(wich u will learn while u gte better)will gladly give a pwn for superior agressif position in chess
an example u will learn....giving a pawn to control the 7th rank with a rook etc...u need more then tactics ,trust me...
