I've felt this same way for a while. I don't play live much, but I typically do well when I do, weather in a casino or "home" games. I quote home, because the home games I play in are more casino level usually. I think some have hit the nail on the head with above sentiments that a lot of online players have no problem with the "push and pray" method. Many having no problem going all in with AX, ATC-suited, ATC-connected or ATC-paired; and unfortunately for us tighter players, they tend to catch a lot. I know, I know... "in the long run...", but the long run doesn't help much when you're all in and they long run away from the table with your $$.
A tip from me though - I have recently started getting into limit online and have been doing much better. For one thing, I have found I can play a much higher priced game. I used to play $.10/$.25 or $.25/$.50, and now I play $1/$2 - $3/$6 without breaking a sweat. It's great because yes, some people still Suck Out
, but at the same time, I am able to see more streets without having to push my entire stack in the middle to do so. And for some reason, I feel I'm getting better at reading the limit players. I'm able to bully tables more, whereas there is no bully'ing with the push-and-pray'ers.
If you still want to play, try slowing it down and hitting the limit tables for a while and see what happens. Start low, I started with $.10/$.25 and worked my way up as I got a feel for it.
On a side note, since my $.10/$.25 pots were smaller, I'm also earning more FPP with larger pots on the $1/$2 limit tables.
Keep in mind, if you play limit, if it's not worth a raise PF, it's not worth seeing. You will have many MANY limpers PF, you MUST try to get them out of the way with a PF raise. If it's raised in front of you, someone's already done it and you can decide to call from there. But, if you are 1st to act or last to act and it hasn't been raised, raise it up or fold.
