Abstract
We study Sarkisov links initiated by the toric weighted blowup of a point in using variation of GIT. We completely classify which of these initiate Sarkisov links and describe the links explicitly. Moreover, if is the toric weighted blowup of at a point, we give a simple criterion in terms of the weights of the blowup that characterises when is weak Fano.
