Here we have a successful player, going to a new "tight" site.

Results? VP$IP 19.8%, PFR 10.46%, AF-T 2.95
Net? NEGATIVE 0.17 BB/100 over 5000 hands , including an unreal -9.75BB/100 at 2/4 (1000 hands)

The reason?
AA: lost 5 of the last 6 times dealt
--AA lost to T9s (calling 3 cold, board T-Q-T-5-T)
--AA lost to T7s (called one UTG then my raise, board 6-5-J-J-Q, completes flush on river)
--AA lost to JTs (called from LP then my raise, board 4-3-8-9-Q, called the whole way, river raise)
--AA lost to Q8o (called one UTG then my raise, board 7-4-8-Q-K)
--AA lost to JJ (called 2 cold when I capped board A-8-Q-9-T for rivered straight)
--AA lost to A7s (called a raise from BB, board J-6-4-5-3 for rivered straight)
AKs: lost the last 5 times dealt
--AKs lost to T4s (called 2.5 cold from the SB, board 2-4-5-3-A, hit runner-runner flush)
--AKs lost to K2s (he RAISED from UTG and I 3 bet, board T-K-A, 2 of his suit, turned flush)
--AKs lost to KQo (board 2-Q-7-K-3--he called 2 cold and called my flop raise)
--AKs lost to AQo (board 8-6-6-6-Q)
--AKs lost to ??--whiffed

I've lost with full houses an incomprehensible 5 times.
I've lost with KK to 2-outers 5 TIMES. Lost with QQ to 2-outers 3 times, JJ to 2-outers once, and TT once.

All within 5000 hands.

Ugh.
