More on flop. With the K o clubs I def. call since the other options really don't make any sense.

hm didnt notice that, was 15-tabling at the time but giving them odds isnt something i normally do, i woulda bet 6 if i was paying closer attention.

but forget the underbet on the flop, more on turn action?

I don't think we can fold, but I don't get why raising doesn't make sense jessyj? Surely draws make up a large part of his range. Elaborate?

I'm interested in what people say because just looking at this spot I think raise but in the moment I'd probably get confused and flat.

I shovel. This could be an Ac, a J with a club, A high, 78, T4.
I'd open the player notes in time in case you stack him.

I think this is one of the situations where it doesn't really matter that much what you do. I could even see a case for folding.

shove over vs an aggressive monkey and flat call vs the rest.
