the softest games are at partypoker, and it is by far the biggest site. they absolutely blew up by advertising heavily during the World Poker Tour events. a big gamble that has really paid off. the games are soft because most of the players are very new to the game. i play there and at the tournaments on pokerstars. in terms of largest sites, rounding out the top 4 are ultimate bet is third, followed by paradise.

i'm going to start playing at ultimatebet, since they are a sponsor for the Aruba World Poker Tour event, and they have satellites to get in. a satellite is when you play in a low buy in tourney, then if you win, you prize is a higher buy in tournament. to buy in directly to the Aruba WPT event is $4,000, and that is the cheapest WPT event. most are $10,000.
i've been playing a lot lately, with the goal of playing in some of these World Poker Tour events. like trading, i struggled at first, then found my niche when i switched from the hold'em limit tables to the no limit single table tournaments on party poker. my next step has been to the mutli-table tournaments. i'm up about $1500-2000 this week, after a 5th place finish out of roughly 230 (+550), a 2nd place finish of 180 (+1900 -- bad beat cost me a thousand here. higher buy-in at this one), and a 3rd place of 360 (+880). adding them up, you can see i've played in a lot of them, and haven't won them all, but the occassional high finish is all you need. hopefully the evolution continues.
the thing with these multi-table tournaments is that they are extremely top weighted. i've been in numerous tournaments where i've beaten out 90% of the field and come away with nothing, or very little. you not only have to play nearly flawlessly, you need above average cards, and you can't have any bad beats. conversely, the single table tournaments payout the top 3, or 30%. i hope the trend is towards a flatter payout structure, like in golf.
