1000nl Raise or call this donk lead from a donk

[c_hoop]

Never seen villian before today. He has been jumping around limits and seems pretty weak. He donated a stack to me earlier on another table where I raised QQ otb, flopped top set on a connected/2 flush board. He check called flop and turn and shoved river into me for 2/3 pot when all draws missed with J6s. Kinda bad.


I raise ATo on the button, villain calls in the BB.


Flop is 679r

He checks
I bet 60 into 75
He calls.

Turn is T
He donks 55.
