I call.

I call looking to show down cheaply.

[Miffed22001]

scary line.

Call, hope hes just overplaying a king.

Its a scary line... Vilian checks, you told him, i got a good king... Still he's leading the turn, which really cant have improved vilians hand...Im looking for a cheap showdown...

Is vilian playing KJ/KQ/KT like this? I dont know...

I make it $50.
