Just finished one up this morning, and couldn't help but think that it was a really unlucky FT. Are any of these spots non-standard?

1) 8 handed, blinds of 6,000/12,000; KK (800,000) runs into AA (375,000)

2) 6 handed, blinds of 10,000/20,000; TT (400,000) runs into AA (250,000)

3) 4 handed, blinds of 10,000/20,000; 22 (1,000,000) calls a 60,000 preflop raise (1,200,000) in position. Flop: AT2 - with 2 diamonds. "Raiser" checks, 222 bets 1/2 pot. "Raiser" min raises; 222 Jams for 2x the pot. "Raiser" calls with TTT.

Sorry if this is being results oriented, but I'm legitimately interested if any of these are actually just leaks that I assume are standard.

PS - sorry that I don't have the actual hand histories, I'm not at home right now.
