Thin raise/clear raise or plain stupid raise? 10NL Rivered flush

[ZingZhang]

Yeah, question's in the title. I'm not especially proud of this whole hand (maybe that's mispaced and it's fine, I dunno?) and comments on how terrible it is are both welcomed and anticipated [img]/images/graemlins/smile.gif[/img]
Ch behind on turn is because i thought he was going for the c/r,villain was very nitty for 10NL, assumed he hit the ace.

Erm, river raise was 'supposed' to put him all in..oops [img]/images/graemlins/blush.gif[/img]
