For week 6's joseki, we're going to be covering the 2-4 invasion point and black's responses to the move. This is more of a traditional play and is not found often in pro games, but it's definitely useful for beginners and intermediate players.
So black has 3 responses to white's play, to secure the corner, to let white choose or to choose influence instead
By playing at A, black chooses to control the corner, and white is allowed to jump outwards towards the bottom side.
If black chooses to play at B instead, white is given the choice of going for the corner, or playing outwards.
Playing within the corner gives black heavy influence and sente, although not shown here, white has to protect his group in order to stay alive. White is pretty comfortable with the result, but it definitely feels worse than the 3-3 invasion.
Choosing to extend outwards is another option. White gets to secure the right side and the result is pretty even for both. There's also a bit of aji within the black's group that forces black to protect once more later on.
Lastly, black can choose to go for pure influence at C. I feel that black is getting too much influence in this situation and feels too good for black to have reinforcements on both sides. However, this is definitely an acceptable playout for white if white can weaken the influence on either side effectively before playing the 2-4 point.
I know this week's joseki was quite short, but I hope this was at least helpful to some! Please let me know if I ever make any mistakes!
