Hands 2 and 4 look good to me...

As for hand 1.... I don't like how you played it...It worked out in the end 'cuz a donk caught his third jack and figured he was golden. (you didn't lose to AJ did you? thats rare in these tourneys anyways.)...I would say you probably shoulda led the flop, though a weak lead is fine. Donked the turn off (check/cheap bet) and valued the river...Sure - maybe you don't stack the guy THIS TIME...but overall a strategy like that will win more I think.

Hand 3
Looks like villian has the 8 or a busted draw. I think you raised too much on the turn if you're checing the flop. Aren't you screaming out your trips? Heres a spot I small-raise (sometimes click min-raise even) and value the river. Value it highish if you want the aggro bluff look you seem to be going for.

Overall not horrible for the 5s.
