You're the chip leader on the button near the bubble. The small blind is a tiny short stack; the big blind is a medium stack desperate to survive. Folded to you with K♦9♦.

Big stack on the button; a committed short SB and a survival-minded medium BB. Best?

WhyRaise. Target the medium stack: near the bubble he folds far too much to protect his cash, so attacking his blind prints - and your fold equity makes K-9 suited plenty. If the committed short stack jams the small blind, you can simply fold.
What happensYou raise; the medium folds, the short folds.  You pick the right target.
At a table of mixed stacks, you read each opponent's agenda and attacked the medium stack - the player with the most to lose and the most reason to fold near the bubble.

Attack the medium stacks near the bubble - they fold too much to protect a cash; ease off the committed short stacks who'll call.
