TRANSPOSITION
NIMZOWITSCH DEF. (Kennedy V.) to SCOTCH GAME
Black's supported KP advance freed his KB and threatened White's QP, seeking to draw it forward.
White transposes into the Scotch by developing his King's Knight to double his QP support (preventing 3..B-B4) and double the threat against Black's KP, reversing the QP-KP attack. W-Alt.
