A short blind battle

M 5, on the Red/Orange border. It folds to you in the small blind, heads-up against the big blind, with K♦7♦.

Short, folded to you in the SB versus the BB, with K♦7♦. Best?

WhyOpen-shove. Blind versus blind and short, your shoving range is very wide - K-7 suited is well within it. Jam to take the big blind's chips and the antes; limping or min-raising with this stack just creates a tough out-of-position spot.
What happensYou jam; the big blind folds.  Wide jams blind-vs-blind when short.
Heads-up in the blinds with a short stack, your jamming range is extremely wide - you're risking a small stack to win the blinds and antes against a single opponent.

Blind versus blind and short, shove a very wide range - one opponent and dead money make the all-in highly profitable.
