Hi, I'm studying for a test and trying to practice with alpha beta pruining. I found this site that I can practice potentially both (minimax with and without alpha beta, it's an applet), but it doesn't show the pruning when I choose alpha-beta drop down option. I copied the image and attached here, I just want to make sure I am cutting off the proper sub-trees. Just want to make sure I'm applying alpha-beta pruning correctly.
**When would it not be any benefit to use alpha-beta, because I know when we have a huge tree (high depth), then we can improve the a factor of its square root so with branching factor: b, depth: d, O(b^d) becomes O(b^(d/2). But when would alpha-beta pruning actutally be an overhead?? Any heap appreciated.

EDIT: My mistake, the applet just darkens the pruned sub trees, so I was correct.
