Yes I bet different amounts ... if there has been a lot of minimal raise stealing attempts in the later stages of a tourney, I will not mind doing the same with aces or kings

If I am shortstacked and been all in a couple of times in a row, I will also go all in with aces


But generally I vary my game ... at a tight table limping from early position with aces is ok

and so on ... different hands different considerations ... I am a follower of Harrington
