Of course, the skill cap of the players changes, in big amount on the tournaments mentioned above. You will see more LAG players and when you play for the very first time you will have trouble getting to know your opponents. Its definitely harder than in lower buy-in tournaments. To go up in entry fees, Im playing according the rule, that I must have atleast 90-100 buy-ins for a particular tournament. So, to play a dollar tournament I need to have atleast 90 dollars. I usually bring 1 to 3 % of my maximum bankroll to one table. Occassionally I play higher buyin tournaments ( just for an example, if Im on a winning streak and win lets say 10 dollars from a 1$ buyin tournament, I could try to play a tournament, just one, for 3 to 5 dollars ). Just to see how it goes. I sometimes cash out, but most of the times I dont, because players are totally different and you have trouble on calculating different situations. Decisions to be made become way too harder to calculate, even when you got the correct odds
. This is why I primarily stick to lower buy-in tournaments where Im more favored to win against players on my skill level, than it is on bigger buy-ins. Of course, when I play once in a while a higher buy-in tournament and if I cash out I just keep the money, I dont sign up for another tournament and so on. Did, the first few times, and it turned so not profitable, that when I do cash now I just keep the money, consider it a BR boost, and stick to my regular tournaments.
When I move up to higher buy-in tournaments I usually save a little more money for the first 10. Lets say Im just starting to play a dollar tournament, I save up to 110 dollars, so that with the first 10 dollars Im trying harder to adapt to the specific tournament, and then play with my original bankroll, which will be down to 100, the way Im supposed to play.
Hope this could be of any help to you.
