I played this just right…right?

I believe I played this perfectly except maybe the river bet.  At that point I was beat by any set, the straight or AK.  I had put him on a good ace, either AK, AJ or even AQ.  I guess he could have had AT.  I felt like on the river I was committed, $5 for a $25 pot.

Up until the king hit the river, I was very confident I was ahead.  In theory, on the turn I should win this hand about 94% of the time, right?  So the big, protect-the-hand bets were good bets.

Is this all right thinking?

I did win my way back up to my original buy-in with just a few more hands of play.  Then it was my turn for quads.  I had 55 and the flop came A59 and I had 2 players with me.  I bet just under the pot and had 2 callers.  When the turn came 5, I didn’t really know what to do.  I figured it was time to show some weakness.  The river was a 3 and no flush possibility.  First player checked with little left in his stack, I was sure he was shipping it all in no matter what I bet.  I just wanted to get something from the other player.  I went ahead and bet out half the pot and he folded.  The first player put in the rest tabling 88, I’m not sure what he was thinking.

For the record, I did lose a little tiny bit against a player who made quad jacks.  Everyone checked it down most of the way with 2 jacks on the flop.  when the third jack hit the river I thought maybe my small pair might make the best full house so I bet small just to see and the quad jacks just called for some reason.

That’s a lot of quads to be up against for just a few hundred hands, no?
