2nd hand, QQ

[Womble]

Was this too risky 2nd hand in the tourny? (10/20 blinds)

Hero is MP2 with Q [img]/images/graemlins/spade.gif[/img]Q [img]/images/graemlins/heart.gif[/img]
UTG folds, UTG+1 folds, UTG+2 calls, MP1 folds, Hero raises to 80 (is this a good size?), MP3 folds, SB calls, BB folds, UTG+2 calls

Flop 9 [img]/images/graemlins/club.gif[/img]5 [img]/images/graemlins/spade.gif[/img]2 [img]/images/graemlins/club.gif[/img] (340)
SB bets 100, Hero raises to 200, SB calls

Turn 5 [img]/images/graemlins/diamond.gif[/img] (740)
SB checks, Hero bets 300, SB calls

River T [img]/images/graemlins/heart.gif[/img] (1340)
SB checks, Hero bets 420 (all in), SB calls

Was this too agressive so early on, SB showed no agression apart from the flop so was guessing top pair. Can you also comment on my betting, am new to NL and tournies so not sure
