Final table problem.

Hi everyone!
Could you help me, I usually get there by late registration, but then I always get stuck for some reason.... does anyone have any tips, I would like to break through this barrier and get to my first final table

Late reg may be a valid strategy for satellite tournaments, but for serious tournament poker play there is more than shoving any AX into a preflop opener.

So learn to play, not only to shove any Ace rag into preflop openers.
Poker tournaments are more than luck in preflop shoves, you need to have a deeper understanding of the tournament structure, plays at what stack level, and much more.
Try to get some insight in good poker content on YouTube, from trustworthy sources, that try to give some basic understanding of tournament poker.

Also, try to take the free course on CardsChat. Winning Pokerplayer in 30 days.
This gives basic insight and a good foundation, from where you can further advance in the poker learning marthon.

For poker as for most things in life a lot of training, study, time, effort (blood, sweat, and tears) is needed.
