K6o BB def against the semi maniac

[thesharpie]

Same guy from my other post. He's not a true maniac though, he won't raise everytime, he's still been raising alot preflop and taking alot of stabs at flops though. He called down with A4 high against a flop check/raise on a paired board HU. We got heads up once since the last hand and he checked down ten high in position against me on an AKx board so I think he thinks I'm a calling station after making that king high calldown, I also think he'll showdown ace high often but then again he might raise it. How do I react to a turn raise? Should I be playing it meeker? Check/call the river?
