re: Poker & killin the game 10/20 limit
STOP, DROP and bankROLL!
STOP playing above your bankroll before the cards turn sour (and they always do eventually). Consider yourself lucky and enjoy the roll you've accumulated. But playing this far above your bankroll is true gambling.
DROP to a reasonable level. It is recommend that your bankroll be no less than 300X the BB when playing Limit Holdem. That would require a roll of $6000 to play the level the 10/20 tables. I personally prefer 500X the BB for limit, but then I am very cautious with my BR. With your role, the 3/6 tables would be much more reasonable...and possibly 4/8 if available.
BANKROLL your way back up to the 10/20 tables. With the boost you gave your roll today, you've gotten a great start!
Hey, CONGRATS on what you've gained, but time to get smart.
