re: Poker & Breakeven/slightly losing for 55K hands
12/8 is not horrid for FR, can certainly try narrowing the gap though. At least in 2NL FR, I'm successfully running 13/11 and getting 12bb/100, and I 24-table FR (yes, inb4 the what are you doing with your life, move up lol posts)
5NL FR I have not attempted for the longest time cause I was 6max for quite some time but our man blackrain has played 500k hands of FR 5NL with like 13/9 and got away with a whopping 13bb/100 hands.
Stop reading, stop bluffing. Observe your hands, learn where to valuebet and when to give up.
