54s in BB

[Hattifnatt]

Like 15 minutes into a $300 online tournament with ~2000 entries. 5k startstack. I have been raising preflop 3 times without any callers and folded the rest of the hands, the table has been pretty tight. CO or UTG have been playing tight and have not been involved in any big pots.

5k stacks

10/20, 10 players

Preflop: Hero is BB with 5[img]/images/graemlins/club.gif[/img] 4[img]/images/graemlins/club.gif[/img]
