I took about a ten year break. It took me one month to get back in the swing and two months before I really got my game back. Stick to freerolls and ticket games on Americas Card Room and Bet Online or where ever you can play.
Check out Twitch and Twitter for freeroll passwords (like Casino.org and Poker Source and Stormers). Watch Collin and Katie's poker course here on Cards Chat (https://www.cardschat.com/become-a-w...-poker-player/). Post often and learn from other players. Enter every Cards Chat freeroll and entry game you can, because those will challenge you most as you improve.
I think itís like cycling that canít be forgotten. There was a time that I missed a year or two because of work, but when I sat down everything went like it used to. I didnít even dare sit in for bigger tournaments because I needed a little warm up. After a gym or two, I think it will work for you too.
You will probably have no issue remembering your game but the game of your opponents is constantly evolving. I am sure you have heard players say that the way they played 5 years was terrible. For most players who care about their game it is truthful that they have improved greatly over the years. You will be at a little bit of a learning curve when it comes to the common tactics of opponents depending on how long you were on the sidelines. My advice would be to watch some training videos and let the narrator talk about playing styles of people. Make sure they are recent videos and this will help you learn the nuances of the game currently. As far as playing, I would stick to freerolls and low stakes to get a feel for the game and then once you have the that feel for opponents, you can slowly start to move up if you choose to.
