I want to win, so keep the yellow ones!

Meredith and I were playing Connect Four Game yesterday. I explained the instructions to her and we started the game. She chooses green chess and I took the yellow ones.

Instructions: Each player chooses either the green or yellow chess pieces to start playing. Take turns to drop a chess pc into any of the seven columns. The first player to successfully get four of their chess pcs in a row either horizontally, vertically or diagonally wins the game.

Wherever she puts her green chess, I blocked her and she asked me not to block her. After the 2nd game, she asked me to keep the yellow chess so that both of us can put the green ones together, then she is the winner lor!

Very smart right?
