What's the name of this structure after white castling ?
i played black with this against an expert
he started with p-kn3 shredder says it is the benko opening 1)p-kn3
so whatever that move is called would be it although it may have transposed to something else which would also be a proper name for it
that was one of my best wins i sacked a rook for knight an a pawn in a semi-closed position and got an advantage in the center while his rooks were not doing much while my extra bishop guarded key squares
p-kn3 p-k4 b-n2 b-b4 p-k4 p-q3 0-0
not sure which order i played the knights but that was essentially our opening position
