here in this situation I would highly advocate a push all-in. The reason is as follows:
1)you stack of 1045 relative to the blinds (150+75=225) this taken into consideration you can only go around the table about 4 more times.
a)pushing will limit the field
b)pushing takes out the consideration of position
c)you most likely have the best hand at this point

2)You must take into consideration the type of hands the raiser has been playing, if he's a tight player just fold and save your 300, the fives just won't hold up enough during this stage in the game.

all-in is the move I would put serious consideration, either that or just plain fold why waste your cash for a 1 in 11 chance that the board trips. If the borad misses him he's going to bet anyway and your pot odds will justify a fold down on the turn.
all-in or fold
