Can sympathise with you. After destroying the tables on Royal Vegas 2 nights ago (100BB/100!), this happened in the hour I spent 2-tabling last night:

1. 1st hand when I opened up my second table...AA. Try to raise it up big then realise I opened a PL table by accident...DOH! Bet the pot, get 2 callers to flop. Rags, but 2 diamonds. Bet the pot, 2 callers. Turn A, giving me the set. Bet the pot, 1 caller. River diamond....lose to a flush.

2. Ready to call it quits when I get AA (in a NL game this time). Bet 10 x big blind and get 2 callers. One is in on every hand, no matter what, other has just joined table. Flop comes K 9 2 rainbow. Player I have no read on bets pot, I go AI over the top of him, other guy folds and he calls. He flips over K9 for two pair and hits another K on the river to give a FH.
