Try to get into profitable spots where you have very good equity. Try to go for as much value as you can from your big hands and if possible, try to go all in with them. Try to pick up pots here and there with tight players. I would play suited connectors for as cheap as possible trying to get somebody's stack.
One mistake people don't understand in Fifty50's is that you should not go for more than one double up unless you get extremely good odds
. Getting one double up will double your money, but two double ups will only triple your money when this will only happen one in four times if it is a coinflip each time.
Good luck and still remember, busting out in 10th is the same as busting out in 6th.
