How to learn poker faster?
Exactly in the same way, as how you learn anything faster. You have to spend more time for it. So simple is that. But i won't say anything new, you shouldn't only play poker if you are really willing to learn playing better. Better if you split your poker time to 2 different parts. Is like 80% of time playing 20% of time learning. (or 70 to 30, depends what fits you better) And at those part of time named "learning" you may read this forum, books, analyzing your own hands (where you are not sure if it was played right, as a help you are welcome to post them here and read opinions of the others CC members), watching poker videos or reading poker strategy articles. Also you may train your understanding of equity and ICM with special software. Anything that gives you additional theory input. Important thing, that you are really doing it regularly. Not only playing.
But playing is important as well. More hands you played, more poker situations you faced, more experience you gained. That helps too. So you probably could play more than just one table, to gain that hands amount more quickly, but don't play too much, so that you still can fully concentrate on decisions.
