Is multi-tabling necessary for a decent win rate?
So I'm still fairly new to online poker - been playing about 2 months now - but I think my game is progressing pretty well. I've also been playing in a weekly live game for a couple of years now, so I wasn't a complete noob when I got started. And while I find I can be fairly successful at the low and micro limits in general, there are still times that I find myself not applying my full concentration to the game, with disastrous results usually following. As a result of this, I feel that my level of play drops significantly when I play more than one table at a time.
I know many regular players like to play 4 or more tables at once, and I've heard some people say that multi-tabling is necessary to get decent hourly win rate. Obviously, for a person such as myself who is still learning the ropes of online poker, it's better to stick with just one table at a time. But are there any seasoned players who still prefer to play only one, or maybe two tables at a time? Are there any who post win rates comparable to those of the regulars who play 8 to 12 tables at a time? Or there largely a consensus that multi-tabling is the only way to go if you want to actually generate some income?
