So now because of the risk of a queen side castle and an attack with pawns against my king. I thought to exchange the c pawn so i can get a semi-open file for the rooks just in case.

the same idea apply here. The pawn are ready for attack if my opponent castle queen side.

well if he had castle 0-0 than the game is almost equal, now it is a little double edge.

the continuing of the a3 idea.

perhaps Kb8 will be better. Also this lets an option for b5..

the aim here was to disrupt pawn structure..nothing more

mostly forced because after Nb8, bxa6 and Qb3 and the b file is open for future attacks.

well i took it with knight because i wanted to exchange it with the black bishop.

well my opponent does not miss a chance to launch the counterattack. Kb8 or Ne4 are advised by the silicon!

well perhaps too early? i do not know..thinking i got rid of a defender and a possible future attacker piece.
