I won a freeroll to a €540 77 runner tourney in Slovenia. Its a double chance with 3.5k starting chips but I took the "second chance" right at the start so I had 7k. I am the youngest player at the table and so far have shown weakness when my 8s got 3 bet and I limped with 44 and called a miniraise to setmine to no avail. Other than that there have been no showdowns and I haven't picked up any particular reads.

I have ATo on the button playing 7.2k blinds 50/100. It folds to MP3 (playing 5.2k) who has been tight ABC and is a mid-30s Italian dude who limps. CO limps behind and I make it 550. MP3 then throws out 4x1k chips making it 4100 total. CO folds. Is standard line to fold here? Whats MP3s range?
