Korlon: This looks very like the 4 5 joseki where black starts off on the 4 5 then white goes to the 3 3 point and black attaches on the outside.
In this case, black 3 is not a recommended move because it does not give as great of a result as the other josekis due to white 4. Afterwards, black can play at a or b, with a being a huge mistake, and b being ok.
Black plays b and white will play at a. Black cuts at c or d and white gets a ponnuki on the side or in the corner.
If black does play at a, then black will invariably atari on one side and white captures a black stone in a ladder if the ladder's good.
