As played is this a simple shove?

very unlikely that he has J. most probably KQ, or pair like 99,TT (because if he had AK he would reraise pre, if he had J like AJ he would slowplay it on flop)
i would shove, calling may trap you on turn or river... however calling also good choice, but i think a bit more risky

thanks for the feedback Onlyvictory.

My nittiness says : "fold you fool, he called on the BTN with KJ or JT !"
The other side says : "He is probe betting with only the K, shove !"

I would shove it though.
