The opening fase is used to develop ones pieces and control the center directly or indirectly with flachettos g3 Bg2 or g6 Bg7.
If you study an opening you are looking to achieve a certain position/objective, when your opponent desviates from the main line of the opening you must try and take advantage of it either by gaining material, seizing the initiative, getting more space etc.
Hope this can help a little bit I do not know much better either :(
- Dear chess people --- I have played chess for about twenty years but
I only push pawns --- I knew about openings from the beginning but
never took lessons and couldn't be bothered taking the time and
trouble to learn openings -- now I think I am stuck in a rut and I
cannot get better unless I learn some openings but I got to thinking
??:? how do chess players use opening? by that I mean I look at the
moves of one -- I think it is called the two knights defense -- well
if you move one move fine , make the second move fine , make the third
move ?:??? now I am wondering -- what if the other guy does not make
the corresponding moves for your particular "opening"??? what do good
chess players do?? do you continue to make all the moves of that
opening??? -- so having thought about it --- long story short -- I
came up with the question I asked you -- namely -- how do good chess
players use the openings?? I would really appreciate if you could help
me with a short answer to this dilemma -- please and thank you ---
--------------------------------------------------------------------
some people could debate the "luck" "skill" thing in chess and they
are welcome to their opinion on that but I personally believe my game
is all luck -- as a player who merely pushes pawns -- well my opening
-- if you call it that -- well I respond "knee jerk" to the moves the
player I am playing against makes --- well if at the end of the
opening my players support each other and control lots of squares and
can move freely and not block each other and my king cannot be put in
check -- I was "lucky" and made a good opening --- however some times
in responding to the other players moves at the end of the opening --
well your pieces can wind up being in each others way and blocking
each other --- your pieces can be "deployed" but useless and not
guarding or attacking any important squares --- and one's pawn
structure could be destroyed leaving no good way to castle --- worse
yet if the opponent can even remotely "put one's king in check" then
He can "check" you numerous times until he flukes a material advantage
-- or even check mate ----- in my personal game I personally try total
attack and if my opponent defends my attack generally then when my
attack peeters out I get whumped --- so many people maintain chess is
all skill but I maintain that unless you are a chess master ( then it
is all skill ) but unless you are a chess master my personal theory is
that chess for lesser players involves about 75 percent luck ---
----------------------------------------------------------------------
So having just pushed pawns all these years I am totally confused as
to how opening work and how good chess players use openings in a
"PRACTICAL" way. meaning what if the player does not make the
corresponding moves for the opening you try to play?????
