QQ vs Maniac with a K on board

[**RivEredAgaiN**]

Villian has played almost every hand for over an hour. Have not seen him fold preflop once he has money in. Earlier hand called $30 allin after limping with 4 [img]/images/graemlins/diamond.gif[/img]8 [img]/images/graemlins/diamond.gif[/img]. Has shown down middle pair after showing aggrestion on all streets. Overall just a maniac.
