I'm not sure, I think it has to do with the weakness of the d5 square. It is a light square, so the lack of a light squared bishop is fearsome for black, since it makes that square even more vulnerable (think of a knight sitting there, destroying black's position since it cannot be challenged by the light squared bishop). Hope I was helpful, relevant and nice!
light squared Bishops

As it says, it's all about the structure. Structure means the pawns. Saving the light square bishop is not a general rule of chess. It helps to post a diagram when asking for advice / analysis of a position.

Black has to avoid the perfect najdorf position for white, which is a strong knight versus a horrible dark-squared bishop. So trading blacks good bishop is obviously dubious
Thanks for everyones input. The game of chess is so much fub, yet at the same time can backfire and cause so much depression, because like anything in life, the more you know, the more you realize you don't know. I still belive if I could dicipline myself and find a mentor to train me, there is a remore possiblity I could become a master in 5 years. I am only 51, disabled due to an accident, and have at a minimun, 6 hours a day to devote to chess. Thnaks for your resposnes. Styat healthy & happy. BobbyD

I don't understand why Black wants to avoid losing the light squared Bishop. Is this comment based on the game I was training on, or is this a general rule in chess. I am sure it's a simple answer. I would appreciate input from any players who understand this comment. Thxs
Based on your rating there are 2 important tactical theme in the Sicilian. After 1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6 6.Bc4 e6 (the White B at c4 and the White N at d4 are dangerously placed to perform a thematic tactical manouver at e6 especially if the Black LSB has been exchanged. The other tactical manouver is centered around the square f5 where White has thematic sacrificial combinations with the White N at d4, if Black plays 6...e5 made easier if Black's LSB has been exchanged off the board.
