Looks like I forgot to follow this post up. Thanks for the considered replies. I'll look the hand up later but I'm not sure what happened in the hand yet. Looks from what I wrote that I did play the hand.
If you aren't certain about the shove here Mars, then you recommend just calling to see a flop?
That line is certainly affordable in the circumstances -could lead to trouble..
I wonder what in fact did happen...will try to find the HH.....
If you're second big stack in a SnG, the last thing you want to do is see the big stack call your preflop raise (same holds in your position - only player you REALLY don't want to play against is villain). AJs is too strong to fold in this position, but if villain is going to win the hand approximately 1 in 6 times (either he sucks out on you or has you dominated with something like KK) it's not worth the loss in chips - if you win, you're in great position to take 1st, but a loss and you're as close to bust as possible. Haven't run the ICM numbers on it but that's my feeling.
Anyway, a call here will tell villain "Hey, I have a hand - unless you hit the flop hard, I'd back off now". Use the stop-n-go here and try to knock villain off the hand. Unless he holds a high pocket pair on a harmless board, he won't want to jeopardize his position in the tournament either.
Playing around the bubble is always a game of chicken. Chicken for the shortstacks ("Should I shove now with K8 or see if I can wait this out?), and for the big stacks (Do I want to go from easy money to average stack on a bluff?). The key to winning is to stay the course, and not veer off at the last second.
