I decided to barrel all 3 streets here, representing the 9, the turn was a good card until he calls. 

my river shove is questionable here as he is representing the 9 too. 

i decided to follow through with my line even though its my tournament life at stake, and he folds after committing a large portion of his stack. 

has he folded a 9 here? it does look like i got there if I'm semi bluffing with 6 7. or does it look like i have pocket 4s or 5s?

I dont normally play like this, but was getting tired and was ok with busting so i thought i'd try out some moves.
