on, or near the bubble, it's pretty much what i will use to base my decisions on. late stage sng play, there is only one correct way to play, and ICM heavily influences your decisions, knowing the basic workings of it, is crucial to be successful in sng's.
your question is a little too general, youd be better off posting specific hands in the HA(hand analysis)section of the tournament forum, just convert your HH (hand history) and post the hand, with reads, and any other info you want to add. the more the better. like, how loose/tight is your opponant? will he fold to a shove often, etc.
in some situations its correct to fold Queens, i dont come accross many which include folding kings, and never folding aces, in a standard 9 man sng.
sng's with flat payout structures, like DON or sattelites it can be correct to fold aces.
