Playing cash games is simple, much easier than playing tournaments, almost all cash players say that winning tournaments is much more difficult than in a cash game.
It is much more difficult for a cash player to learn how to play tournaments than for a tournament player to learn how to play cash games.
The difficulty of the cash game is that the game goes on all the time with deep stacks, and therefore the range of hands will be much wider than in tournaments.
That's not really true, it depends on quite some different factors offcours. Deepstack isn't unique for cashgames really, and if u get deepstacked u can easily leave the table. That's probably the biggest advantages of cash games, that you can exactly choose when and how long you play for. And the range of hands you play won't rly depend on the game you play but rather what kind of player you are, personal strategy.
In general you could say that skill level & difficulty of the games will be higher on cashgame tables, as those have the more regs or skilled grinders that can use HUD and mostly play against much of the same players. That is mainly for the low stakes ofc. I used to be focused & preferred to cash games, now more tournaments. In general variance is greater in tournaments, how the game evolves, blind levels & stack sizes etc, But if you play different tournaments at once that won't really be an issue.
When I played cash games again sometimes what I notice is that you can quickly lose more than you usually would in lowstake mtts. Unless you play big buyin tournaments ofc. Like sometimes I play well and win some good money in cashgames, but a bit later I get some bad luck or bad beat, and lose all winnings & more. If you play tournaments with good
bankroll management, swings will normally not be so great.
When playing cashgames tho I prefer the "Zoom" format.
