You should have a few options. There"s a poker club in Kings lynn and the address is The maltings Poker Room,Page Stair Lane,Kings Lynn, PE30 1NQ. I"ve never visited, but they open 3 nights a week with freezeouts on thrusday and saturday and a rebuy on friday. There is a poker club in Norwich which has tournaments sunday,tuesday,wednesday,friday and saturday nights. This place has some pretty loose cash games with lots of money being chucked around into the early hours. There is a Rileys poker club just over the road from the Norwich Poker Club. Here they have a freezeout on a sunday night and a rebuy on monday. Finally, APAT regular Andy (Baldusnew) Cunningham-Brown organises a deepstack at Holt Football Club about 3 or 4 times a year. There"s one today and it might be worth sending him a PM to find out when the next ones are planned.
Hope this helps.
