मध्यमश्चेदनुगृहीतो विगुणः स्यादमित्रोऽतिसंधत्ते ॥ कZ_०७.८.२२ ॥
madhyamaś ced anugṛhīto viguṇaḥ syād amitro ’tisaṃdhatte
If the middle king is favored, he may become “defective” (unreliable/ill-behaved); and the enemy over-commits (seeks excessive alignment) [in response].
Moral hazard: once supported, a partner may slacken discipline, demand more, or act contrary to the supporter’s interests.
The opponent may react by over-investing in alternative coalitions or concessions to neutralize the advantage created by your support to the madhyama.
