just go to the cinema
For 9 hours ? Don't thinks film start at 9 also
Never been to the cinema by myself before tho
there's always films on early, cartoons and stuff
then find something else to do after, with £900 in your pocket there are an awful lot of things you can do that are a hell of a lot better than sitting in a bad game that you're not rolled for
sounds like a great game.
Forgetting BRM considerations, my advice would be to stick on the £4 and feign excitement at doing so in order to get a loose image. Investing only £4 seems pretty cheap if it means there will be and extra £24 going into the middle (even if you are OOP). Also you can pick a perfect stack size to go with against 3 players who are going to be going to war with each other and spewing hard vs a snug shortstack strategy.
The big stacks obviously aren't playing well if they will £8 and £16 straddle with smallish effective table stacks. The bigger and more ego centred the game can be kept, the longer the big stacks will stay in the game and battling each other to get unstuck imo.
