Hello, I'm playing my first ever day 1 of a 2 day tournament soon. Do I need to adjust to how I would usually play a 1 day tournament?

Info:
$500 entry
Multiple day 1s
25 min blinds
Rebuys allowed
Play to 12.5%
Remaining players at the end of Day 1 are ITM.

Side note, the same tournament last year got over 700 unique entries, so I'm assuming the same again for this year.

Thank you

Since it's a multi-day and they play down to 12.5% of field, it likely means that they will push back the blinds on day 2 to whatever level the quickest day 1 finished at.

So don't panic if you are still in it close to ITM, but have a very short stack. Even bagging a 7bb stack might magically turn out to be a 15 bb stack when you start day 2.

Given its a 2 day tournament the blind levels will likely be a little longer than the tourneys you usually play and the field will likely be stronger (unless you are at the last day 1 where it can be anything). Though at 25 minutes its fairly normal.

Also note that Day 2 levels may be longer than Day 1.

So I play a little tighter than I do in 1 day tournaments where I fell like I have to improve my stack much more quickly.

For example in the Super Senior WSOP last year after day 1 I had like 20 blinds. But on Day 2 I managed to crush it and expanded my stack significantly because of the table I was at (and because I hit some big hands while other players had slightly worse hands).

So be patient.

Also understand that it is far more difficult to go deep with 700 players than with like 150. So I don't get too upset when I don't go deep.
