JMHO - anyone that plays poker online for real money needs their head examined. Sites are full of admins with God accounts that can snoop anyone cards.
Been playing on PS for about 7 years and PKR (the 3d site) for about 5
STT ($22 sit down) or max of $1/$0.50 cash tables.
Lost quite a bit in my first two years - now make about $250 per month, last month I ended up down was November 2010.
Nothing major, never seen any of the phenom you speak of. Losing with a full house with a two pairs on the table is as common as muck with one pair on the table (after the river) it's still a decent chance (other player has a pocket pair with the set card on the table)
If you are at a six seater or higher with someone you have observed for 2-3 hours and they are still in the pot with a pair or better on the table (and they AREN'T a novice or a known bluffer) then there's a very good chance they have a percentile hand. I play maybe 200 hands a night on a solid night and during the course of a week I'll beat a full house a couple of times a week normally with a better full house though sometimes with quads.
I see people get giddy all the time with a full house when they don't have the nuts. Same as I see people do it all the time with a flush when the chances of an overcard is likely and a known solid player is sitting in the hand with them.
End of the day, if you get your full house early - or at the point when you have two pairs or a set - you want to win the hand THERE with an overbet not piss about letting people catch a break on turn or river.
Likewise if you have the nuts full house you want to hold players in the pot. TO many though a FH is just an FH - and they make basic odds errors and end up losing.
I use stat software (PokerOffice) and know from the 100,000+ hands recorded in it that the cards I've been dealt are statistically completely legit over this very large sample
Full house is something I rarely see played properly. Along with the low flush..the two hands that break people. And if you play enough poker you see it a lot.
