Hi Adem, the postive is that this domain is catchy and brandable, and that most of those types of poker domain are taken. That said, I am skeptical of domains that are not more generic - where one word in the name is replaceable with may others.
My guess is that this is one that would struggle to sell as is to domainers generally looking for good sales (unless it is getting residual traffic) but you should still keep your eyes out for someone who is looking for a "brandable" domain in this area. In the latter case I'd see £100-250, with any more than that sending them searching for another "poker(word)" or "(word)poker" instead.
