       So White instead plays a very AI move, just plays away. You might think White is ignoring Black's attack, but really it's just playing very lightly and de-emphasizing the right side and I agree with this strategy. By refusing to fight on the right side, it's going to make the invasion at the 3-3 in both the upper right and lower right corners very effective moves. Plus, White is getting something back on the left-hand side of the board.
