What's YOUR MOVE?

Whats YOUR MOVE?
You're playing TIC-TAC-TOE (noughts and crosses) with your 5-year old niece. You are X and it's your move.

Where do you place your X?
A. on the GREEN square for the WIN, or
B. on the BLUE square for the BLOCK, or
C. on the RED square so your NIECE WINS when she places her O on the BLUE square

Please explain your choice in a comment/opinion.
GREEN - WINNING is EVERYTHING
BLUE - CAN'T LET HER WIN
RED - LET HER WIN
QUIT the game - it's time for cake and ice cream
