Tournament all-in showdown -- players show:


My reads. My opponent was a solid player playing tight/agressive throughout the entire game. At this point, given their stack size, they were raising every hand by 600. I obviously needed to make a move and thought this was a good time.

Any thought as to the move, or should I have waited?

In tourneys, both sit n go and MTT, this seems to be my trend lately; getting to ITM, but being significantly short stacked to players. I think I am going to start switching gears earlier to build my stack going into the cut off line.
