First and foremost I am far from a poker genius, but like many of us I am a scholar of the game, so what I offer is suggestions (from a scholar of the game).

Anyway, I personally don't agree with your call KQ call: Two shorth stacks went all in before you, you can be 90% certain they are going all in with Ace high or any pair, meaning you're pretty much racing (or 60-40 with one) with two players; I think this unnecessary, especially cos you were not short:  you are putting your chip position at risk. You should let the short stacks take each other out, unless you have a really good hand. Short stacks are going to play desperate poker, so let them fight it out and let the blinds eat them up.

By the way, by Slanski's gap concept you should toss hands like KQ when two people shove.

When it comes to overly agressive big stacks, I would suggest a pacient approach: wait for the right time, then take the bastard's stack!

Lastly, I am a HUGE supporter of stealing blinds. My rule is: when in position loosen up and commit larceny, especially on the final table (eat or be eaten)!

I'm struggling with cashing in live freezeouts. I'm going deep, oftentimes not even being shortstacked at the final table, but then something just goes wrong.

Last night for example, I called two all ins (button and SB) from my BB position. Had both of them covered at least 3x. I had KQo, SB had A9, and button showed 77. Nothing hit the board for SB or myself, so SB took the sidepot with his A, and button took the rest. Now knocking them out would have put me with a very healthy chip stack and the tournament bubble (4 left), but I couldn't seem to recover from that and instead of damaging the two players to my right, I helped them.

Was my call incorrect?

Secondly, which hands should I be playing and how?

There was a big stack on the table that was keen on shipping all in as soon as anyone raised, so it kinda forced everyone to all in decisions with every hand they got?

Which hands should you be going all in with? I had suited connectors a couple of times, but wasn't confident enough in them (9,10 and 6,7).

Is it all about position play, or can you make moves out of position? If so, what and how?

I really feel my game is solid to get me to final table, but something just happens at the end. Perhaps I should loosen up a bit?
