Should i valuebet this river ?

[sdv]

If he is retarted and he has has KT-T9 he could call 100$, and i don't need image against him (also we could easy fold to RAI).

Against regular we have 2 options - push and check, and check looks really sucks. But I think it could be more deeper hand then "easy shove" against such type of player, cause we have option bet like 100-150$.
