Do I suck? Legends hands

[PokerCad]

First level
I'm UTG with AA I raise 300 fold around BB calls, Flop 10-X-X, two clubs BB checks,I bet 750, BB call, Turn 10, BB checks I bet 1200, BB calls, River X no club BB checks, I bet, BB chek raises 3000 I call, BB shows 10-6 clubs. Would anyone have folded the checkraise?

5 hands later,
I have KK, LP, It's bet 300 to me, I re-raise to 600, fold around to the original UTG raiser who calls, flop 7-7-3, UTG bets I call, turn X UTG bets I call River X UTG bets I raise all-in, by now I only have $2300 with the previous beat, UTG call and shows AA. Where did I make my mistakes or just bad luck? First hour summary, AJS, QQ, KK, AA and lose all 4, this tournament suckedjavascript:void(0)
