(;B[qc]C[Hi! Let's look at 3-3 josekis. Playing at 3-3 is a more territory-oriented choice than any other move. But because of its low position, it doesn't provide much influence towards the center.]
;W[pd]C[To exploit that weakness, White plays a shoulder hit here. This move intends to build influence in the center.]
(;B[qd]C[In response, Black can push in one of two directions.]
;W[pe]C[After that, White stretches. Now there are two possible josekis.]
(;B[pc]C[This first option is to push here.]

)(;W[nd]C[In this case, White should jump here.]
;B[oc]TR[od]C[Then Black stretches to prevent White from playing a tiger's mouth. How should White play now? White needs to defend the marked weak point somehow.]

;W[oe]
;B[ne]C[What if Black pushes and cuts?]
;W[me]C[White can simply capture this stone in a ladder. Because of that, you don't need to worry about the cutting point now. White makes good shape with the knight's move.]
)(;B[qf]C[Black jumps here, and this is a joseki. White managed the white group lightly. Even though Black took the corner, White can play elsewhere and take a big point. White can also play O17 now, if that is an important point.]
(;AB[od]C[Continuing here isn't usually big for Black. Continuing will make White give up two stones, though. This is because the ladder no longer works.]

)(;W[qe]C[In this case, blocking here is a proper move.]
;B[nd]C[This knight's move is still good for Black.]
(;W[qi]C[Then White extends here. White may choose this joseki when White doesn't mind making territory on the right side in exchange for the upper side.]
(;AW[ld]C[Somebody said that this looked good for Black. But Black's position isn't entirely secure. A move around here or on the third line exposes a weakness in Black's shape. Because of that, the upper side isn't as big as it looks. So this variation is a joseki.]
)(;B[jc]C[Black may extend here to secure the upper side territory. But it's gote. In addition, modern Go emphasizes plays in the corners over plays on the sides, and this is a move on the side. So Black usually won't play here right away. But it's a possibility when the upper side is important.]
))(;W[qj]C[White may extend further in some cases, but it's less common.]
;B[nf]C[Later, Black can jump here and threaten to split the White stones.]
;W[ph]C[So White feels compelled to add a stone around here. White wouldn't have to do this if the extension were one point closer.]
)(;W[pi]C[White may also extend high on the fourth line for more influence-oriented play.]
))(;W[md]C[If the upper side is important, this two space jump can also be a good move. But in isolation, AI slightly prefers the blocking variation shown earlier.]

)(;AE[nd]
;AW[md]C[To prevent this, White jumps to here.]
(;AW[qe]C[If Black plays elsewhere, blocking here is a powerful move, same as before.]
)(;B[rf]C[So Black normally plays a knight's move here again. Up to here, this is the second of the basic 3-3 point josekis. Black got the corner. In contrast, White gained influence on the outside.]
(;W[ph]C[Before AI, White often concluded the joseki by jumping out to here. But Black's corner territory is now considered to be more valuable than White's influence, which can be reduced later. So White commonly omits this move now.]
)(;W[jd]C[If White continues in the local area, jumping out here can be good for the upper side.]
