Well in my limited experience at both sites, I started playing for real money
about 3 months ago.
I must admit that sometimes I do see tendencies like more Spade flushes appearing or no Ace on a board followed by an Ace board, which makes playing A+rag easier (rag being 6/7/8 or T/J.)
I actually saw a Tendency one time that brought a lot of 82
to the board so I switched and played these horrible hands at least to see the flop, damn me but I won a few nice sized Pots even if the 'Chat' re. my play was full of @@##$!@#
At other times especially in tournaments I often see either Big Stack always wins a push from Short Stack (FTP) or vice versa on (Stars.) Could be the other way round though depending on my alcohol intake - position of the Moon - whether I was actually at a table and playing etc
