Without knowing traffic, this is still two of the
best keyword combinations, ofcourse the .org
hurts it a little, could be developped into a poker
training or poker tips/school site (suits the .org)
most poker sites you see advertised are .com or .net,
but the keywords are still strong.
I would say $20k to $30k, and I might be on the conservative side.
Will be interesting to see other opinions.
