Sorry I cant remember the exact details as I don't know how to retrieve the hand history on this site but the story goes as follows.
I was playing on a site I rarely play cash games on and have no knowledge of any of the players styles. I sat down on a $2/4 cash table. Played BB and then SB and then 3rd hand on button got dealt
Ah
UTG limped for 4, UTG+1 limped as did player in mid pos
I raised to $20 on button and UTG and UTG+1 called. Player in mid pos folded so c. $70 in pot
Flop
UTG checks, UTG+1 goes all in for c $380
Do you call (all in for the rest of my $400) or fold and why?
