Preflop: Hero is Button with J[img]/images/graemlins/diamond.gif[/img], J[img]/images/graemlins/spade.gif[/img].
UTG folds, UTG+1 folds, UTG+2 folds, MP1 folds, MP2 folds, <font color="#CC3333">MP3 raises to t300</font>, CO folds, <font color="#CC3333">Hero raises to t900</font>, SB folds, BB calls t657 (All-In), <font color="#CC3333">MP3 raises to t1735 (All-In)</font>.

Should this have been played any differently?
Is this an auto call at this point?

Thanks
