I don't understand MTTs

[Jonathan]

Here are two hands from a Pokerstars satellite, 500FPP, top
nine finishers win an entry to the weekend satellite to WCOOP #15 (worth 5000 FPP).

The preflop (and postflop) play completely baffles me. I'd
appreciate it if you took a look at this and explain to me
what these people might be thinking. And what is the proper
line to take. Thanks.

My 500 flop bet was misclick...I meant to bet around 400...
but thats not important. What is drig habit thinking? And dominos? And can Spectrum really think that his TPTK is
any good after this kind of action?

I don't understand the thinking here, and I don't know how
to counteract it.

Hand 2....Final hand (for me)
NB. This is NOT a bad beat post.

PokerStars Game #2174882894: Tournament #10403283, Hold'em No Limit - Level IV (50/100) - 2005/07/24 - 08:45:47 (ET)

In this hand I have almost 10BB, and there are 4 limpers to
me in the BB, so if I have garbage, I'll just check and see
a free flop. Why would I go all in unless I have a real hand?
I just don't understand bridgemaniacs isolation play in this
case. There is just no chance that the BB would be raising
allin with a hand that does not beat Q9s.

What is going on in these peoples minds?

Thanks,
Jonathan
