@TeraHammer : So the black bishop has more value than white bishop. Since losing the black bishop would give you more pressure to the King. Sometimes i use black castling but i forgot to keep my dark bishop, that's why i feel lots of pressure after that.
@bbracken : Thx a lot for your explanation, i think i get it. So in your opinion black castling is better ?
@all : Thx for your comments and shares, i should rethink about my castling structure. But atm i think white castling still suit me more, since i always play with it (except on Bird opening). If anyone has another opinion, please share it. I would be very appreciate it.
Sorry for my misinterpretation, since my english isn't very good. Can you explain me the difference of "part of a strategy" and "a result of tactics". Furthermore the difference of "stategy" and "tactics" ?
Buy the Kurogkug big book of strategy.
