Reviewing my play I do not think I did anything special or different from normal. I started tight, looked for opportunities to play cheap pots in position and make the odd steal, looked for double up opportunities with strong hands and generally played conservatively until the last 25 players or so, then I upped the aggression and started picking on small and medium size stacks. I called a few all-in 3-bets with the worst hand and won most of the races. I upped my aggression further as we approached the bubble picking on stacks of all sizes but rarely getting into a confrontation with a big stack - if they played back at me I either called or folded and kept it cheap until showdown. I was chip leader going into the final table and tho I agreed to pay the bubble boy I turned down all ideas of a chop until we got to the last 3. Even then we played for 40 mins or so just going round in circles until we agreed an even chops (better than second place money).
Prior weeks I played the same way but just lost races (kk < AQ), (kk < JJ) - seems KK might be my problem :-)
So a nice profit and first tourney I've won in a few months - its a good feeling.
