I play on Full Tilt Poker quite often, and I agree that there haven't been very many pros on there lately. Most of the pros are not playing on FTP because they are in Las Vegas at the WSOP. The pro that I have seen on the tables the most as of late is John Juanda. I have also seen/played with Chris Freguson, Phil Ivey, Howard Lederer, and Andy Bloch. However, they haven't been around too much in the past few weeks and I can understand why.
As for you seeing Aces full three times and two occurances of quads, I have not seen this happen while I have been playing there. (Or at least not over a short period of time) I have been at a table when a 4 of a kind has hit maybe once or twice and seeing a full house is quite rare, as they should be. I am not sure how many hands I have played, but I have approx. 1300 beta points. I am not sure how many points you earn per hand, but I have played hours of this software, and the occurance of big hands does not seem to be out of proportion. |
