6 was the standard raise, however seeing as everyone was calling it I should have thought to make it more, people were folding to a guy who raised to 10, so maybe I should have tried 8 in order to get heads up against someone.
Yh my thoughts are that 1) people call £6 with the same hands they call £12, so we snap print money off them there with TT and 2) playing 100bb's we're going to be able to value bet and protect our hand better in a bigger pot with 100bb stacks
