The aggressive player might stay back to get a shot, but it's a big blunder. Right now, red has substantial potentials for a pure racing game, because even though white has a slim advantage in pip-counts, red is leading in bear-ins. Thus red should jump over the white's 4-pt prime with both of his back men.

As it's shown in GNUBG's analysis, even after running, red is still the underdog, but with a so much little margin that makes it theoretically incorrect for white even to dare to throw the cube.

(PL, i replace the tab characters which sometimes get interpreted and displayed as a meaningless   with a single space to improve the readability .. otherwsie, a fine problem and analysis .. sixty)
