Opinion if this was the right play

[lpro]

Personally, not the right play although you failed to mention the size of your stack and the size of the other players which could make a difference. You have to figure you are beat by at least one of the other players. The fact that you had the best hand is pure luck.

With the blinds so small compared to your stack you were in no way close to "desperation mode". There were going to be much better opportunities to get your money in. To risk 50% of your stack on a hand where at BEST you are a coin flip and probably buried with AQ or AK or even worse - a big pair in my opinion is not a good play. A J suited is a good hand to bet your money with, not call after 2 players are all in.

Please don't take this the wrong way, but this seems like an extremely loose and fishy tournament. You have 4 of the first 6 or 7 people at a full table flat calling the BB, and then a small blind making a substandard raise of LESS than 3x the BB, with suited connectors. Then, after you flat call, someone with Q-10 off, a terrible hand, goes all in? And the guy with 10-9 suited calls? This seems very bizarre play to me, extremely loose, and if you knew that this play was atypical of the rest of the tournament, calling with AJs really isn't that bad. However, in a normal tournament setting, I'd have laid this down in a heartbeat. You're too likely to be dominated and don't want to play this hand with 2 others anyway.

was this a freeroll tourney or something? This hand sounds like a joke. I probably would have mucked aj with the 800 raise. You have 10k in chips, why risk half your stack with the worst hand in poker, aj?
