thank you
what is sbetter long casteling or short casteling?

A very important thing is to learn to look at your old games (analyse). So why not take a look at 5 or 6 of your games and ask the question: did I castle the right way?
If the King Side pawns were loosened in the opening, f, g, or h were pushed, then players will often castle Queen Side. Opposite side castling can lead to pawn storms, as both players can charge down the board without undermining their king's safety. The pawns loosen up the defense and pieces follow. Often the player who is quicker to attack (time advantage) wins. This can be successful for weaker players as defense requires accurate play and attacking is more tolerant of mistakes. For stronger players (not me) pawns storms are less effective as a superior position wins.
