10/20 River blocking bet

[JMa]

10/20 PL 3-handed on party. Effective stack is $1940.

Villain is button and makes it $70. I have QdQs in SB and I make it $190. Villain calls. Villain does this alot with sub-par hands, once he completed in sb w/ 3d5d and I made it $100 in w/ 77. He then called my CB when he hit a 3 on the flop.

Flop is Js Ts 4h. I make it $320, he calls.

Turn is Ah. I check, he checks behind. I think he would have shot here with KQ.

River is 7s. I fire out 400 into the $1k pot with $1k behind. He immediately push. Is this a bad blocking bet? All draws made it. I just dont wanna get bluffed out by 88/T/J.
