I've read conspiracy theories about how online poker software is designed to move tourney's and sngs along so that players will bust and go spend more money at other tables and so that the company can squeeze more games in. After this one, I'm just about ready to believe LMAO!
The other theory I have heard is that the software is created so that it favours the larger stack with the worst hand. This particular hand doesn't apply because the winner was clearly ahead most of the way but after about 30 hours this week, I've seen the large stack with the worst hand suckout or win coin flips ALOT, including myself when I was the big stack. ie. A2 vs AK and the 2 comes or AA vs 77 and the 7 hits etc..
