74 ( +1 | -1 ) The meanings of chess openings #1Hi fellow chess players, Every chess opening has a meaning...I have studied most of them, but some still confuse me. The first question i may want to ask, is what is the meaning of the Ruy Lopez? I know if your opponent moves his Qpawn, it will force his knight to stay where he is... But what is your opponent does the Morphy defence...and you are not planning to go for the exchange variation...you would have to move backwards...isnt it quite useless for the opening that fights for the center? Why not just start with the Giuco?
My second question... I usually find myself trying the Sicilian, then my opponent does an unusual move..? what should I do...keep going with my plan...or do another move?
"isnt it quite useless for the opening that fights for the center?"
Not at all. In the Ruy Lopez Morphy lines, yes, it takes White a lot of time to set up pawns on c3, d4, and e4, but once he does, he has some decent freedom of movement. To balance this, Black will have a number of moves to mobilize his forces, hoping that his piece activity is vigorous enough to counteract the space advantage White will secure.
Why not the Guioco Piano? It's a sound enough setup, and fights for the center too; perfectly playable. The problem is that it doesn't place enough pressure on Black from the outset; at least in the Lopez, Black has to worry about losing his e5-pawn after White castles and he probably has to worry about trying to develop faster than White so that he has some assets to offset his space disadvantage. So even though the Guioco Piano is faster in terms of piece development, Black has relatively fewer problems; all he has to do is keep up with White's pace. If White then tries to take time out to set up c3-d4-e4, Black is plenty fast enough to stop it. In the Lopez, he does usually not have the time to stop White's central ideas (unless Black does something like sac a pawn). White has various options in the Guioco Piano too; in some cases, he can give away a pawn to divert Black's forces and so speed up his plans, for instance.
On the Sicilian (well, on playing chess in general):
Never ever follow a plan blindly. If your opponent does something you didn't expect, take the time to ask yourself what the benefits and drawbacks are of the move he just played compared to the move(s) you were expecting. From this information, you'll be able to get some idea of what defensive moves you may potentially need to make (neutralizing the benefits of his move/idea) and what attacking options you have (exploiting the drawbacks). From this information, you can either formulate a suitable plan or continue with your old plan if you feel that the move does not significantly change the position.
