And when no good cards come what to do?

You must have breadth in your range and game, it should be taken advantage of if the tournament is already advanced because there are players who fold waiting for prizes or prize jumps, as they well mention if you only expect good cards it will hardly be possible to win a tournament, you must be focused on the game and take advantage of your cards, the bluffs, the opponent's weaknesses, the situation of the game, etc.

well my friend, in poker you can't expect good cards for a long time, especially if you are short stacked, of course if you have a very good amount of chips you can be patient and wait for hands that play the post floop well. Now if you have a few chips there is no way, you have to wait for some GAP to reach you and push all in with the correct range you have to give when you are short.

If nothing good comes when I play cash games I just leave and try later

When they are not good cards for a long time, try to lower them with all in

You put in some and if they dont get out god bless you

Every hand is playable, some more than others. Make sure you keep your frequencies in line and go for it. If yoy wait till you have a premium hand, people will dip the pot before you can even click on raise

run and wait for the best moment
