Freerolls can spoil your game if you play every game and forma the same way.
...But learning how to play good quality poker, by necessity, requires the ability to adapt to:
- the format,
- stakes,
- the stage of the game and
- the playing field.
Sure you can just do it by maths and play GTO...but that leaves money on the table. And simply having the highest
equity in a pot doesn't mean you're going to win it when the whole fishy table is calling your AA shove pre-flop.
In general, I think freerolls are a fine way to play to have fun, or to play and build a bankroll. But if your goal is to become better at playing poker, you need to be able to find the path to vicotry in whatever your chosen game is. In essence, you need to find, hone and exercise your "EDGE". In freerolls, that edge usually includes being very patient. PLaying tighter than the loose fishy table you're up against. Since freerolls are full of call stations, you need to put away the big bluffs until later in the game as you simply cannot
bluff a call station off a pot.
By the same token, when you hit big, avoid slow playing against a loose table. You're not playing aghainst scared money here...so you'll often get action, even with over-sized bets.
Freerolls are better than play-money-chips since they have real prizes of value...but they suffer from many of the same issues as play-money-games since your opponents don't have any skin in the game. This attracts the "shove-any-two-cards" type of players (ie the gamblers/bingo players).
I've written previously on the topic of stratgies for winning freerolls. They can be won. And you can do so without sacrificing your solid background in strategic play. You just have to remember, that in a tourney with 2000 people and only 5 tickets to be won, the path to glory will be littered with failed attempts. Don't expect to win very often. But you should be able to get into a position to cash in several freerolls per week by playing solid poker.
