I seem to have the most trouble playing the middle stages of (9-max) SnG tournaments.
While the beginning is straightforward, and the late stages are something I usually have no trouble with, I probably have huge leaks in my mid game strategy.
For example, if I have 1200 chips, with 100/50 blinds, and the table is 5-7 handed. How should one play hands like AQs+, TT+ from UTG? Simply raising could get me a nice shove. Shoving myself again is not something I would fancy doing in standard/turbo formats.
Also, what should the range be when shoving over limpers at the middle stages of the tournament?
