Grinder, I hope you have Poker Tracker. Go back to your 10NL winning hands and look them over. Are you saying that those wins are all due to your poker expertise? Or are there quite a few in there where fish called you with T8o out of position and you took them for a bundle?

Your jump from 10 to 5oNL is, shall we say, unorthodox. But I will hazard to say many of the regs have seen it here in this forum before. Now that you know you can beat 50, you will have it made. Good luck....
