Live nlhe blinds 25/50.

I raise btn $125 JQdd, sb calls and bb calls.
Flop is Kd 3d Tc, Checks to me,i bet $300 only sb calls/
Turn is Ah, checks to me i bet $800 sb calls.
River Ad. Sb checks.

Now otr our betting is super strong here. Haivng J and Q of diamonds made me felt that he has so little diamonds that could call the turn with. I'm also not sure if sb would flat 33 or AT type hands (LOL @ live poker).
Can we ever get call by worst here?
