I think following the action that occured on the turn we're probably against a strong range that looks like this, that does'nt have many bluffs with no equity :
Straights : KJs
Sets: TT ; 99 ; 44
2 Pairs : QT / Q9 / T9
P+Straight draw : JJ / QJ / JT / J9
We see that there's way way more hands that we beat compared to the KJs that beats us. Adding the fact that we still have almost 23% to improve to a full house if we are beat now, I think this is a call and "hope he doesn't have it"
