Whats the better play

I just got knocked out of pokerstars freeroll in position 27 out of 6271, i was dealt AA, the blinds were 25000 and 50000, i was in early position 1 after UTG, i had about 300,000, raised 100000 ... slow playing because i wanted a caller so i could get some chips for a possible final table. i got my wish , guy called all inwith KJ suited and by the river had his straight 9-K. I'm sat here with my measly 80 cents thinking if id all inned he would of folded and id be still in with a real possibility of a final table. what was the better play? can I be assured I made a reasonable play and just got unlucky or is all in the better choice?

You didnt play the hand bad as you got a caller and had the hand isolated to one caller because of your raise. You went into the hand as a big favorite and lost. I dont think you played it bad and as weak as some of the players are in freerolls he would have probably called you with any 2 paint cards as players think thats any 2 face cards are the nuts no matter what the raise is in front of them.

to tell you the truth its a depends question, i need more info like stack sizes, i know you said you were in early position but you have to be more specific. Personally i would of just hit the all in button and take the blinds if i had to.

I agree with bob i probably would have went all in and been happywith the blinds and thenit depends did he have an inside draw our outside draw. Also was he all in efore the str8t hit

Ya just never know, I would have probably went all in! but it's a freeroll and and even in a low buy in tourny your liable to get called and lose anyway! it's happened to me a lot.

Thats just a run of bad luck. What I've learned from experience online is to never slow-play big hands someone will call, and with the rate you get big hands online, you're bound to get a pay off

In a freeroll I always go all in with AA because someones always gonna call anyway. Least that's been my experience and I play a lot of them.
