I bet you`re very much relieved after that last blog on pawn structure.The Sargossa opening is played by 1.c3:
This is an uncommon and "bizzare opening". I somehow won with that same opening. Here are the strengths and weaknesses of the Sargossa opening:
strength- can set up a pawn chain on the a1-h8 diagonal(it starts at b2)
weaknesses- limits the squares for the QB to fianchetto and the QN can`t go its best developing square-c3
Thx for viewing!
