;W[qf]C[Hi! When I was an intermediate player, I was afraid of losing games. As a result, I used to be too scared to play games. When I look back on that time, I think I should've played more games. You're a probably a beginner trying to get to intermediate level. Because of that, you don't need to worry too much about whether you win or lose. All you need to do is enjoy playing Go. I hope you enjoy this lesson too!]
;B[nc]C[In Lesson #4, we learned about the one-point jump from the 4-4 point. Here, we're going to look at the knight's move. In response to White's approach, this knight's move is a solid answer. It's played not only by you but also by professional players. Compared to the one-point jump, it's safer and more secure. If White invades at 3-3, you have to give the corner to White though. This is one of the characteristics of the 4-4 point. ]

(;B[mc]C[Black can play elsewhere, but defending here is a good move.]
)(;B[ld]C[If you want a lighter move, this knight's move is great. This result is good for Black, too. Therefore, you don't need to worry about the immediate 3-3 invasion. Such an early invasion isn't good for White. It allows Black to develop too much influence.]

;W[qd]C[Some players let White connect like this. But it isn't good in this case. You should split White first.]
))(;W[rd]C[This knight's move is a proper answer for White.]
(;B[qc]C[Defending the corner at 3-3 is normal. However, in comparison to when Black plays the one-point jump, the 3-3 point isn't very urgent.]

;W[ob]C[White will slide here again, and it's bad for Black.]
)(;AE[qc]C[Recently, Black doesn't answer at 3-3 quite as often. That's because modern players focus more on sides and the center than before. Let me show you a joseki.]
;AB[qc]C[Black answers at 3-3 first.]
;W[qi]C[We learned about why White has to extend here earlier. This is the end of the knight's move joseki.]
(;B[rc]C[Some players, however, play here immediately. Undoubtedly this is big, but you should play it in the endgame. There's no need to play it now.]
