Stupid or Brilliant?

[burgi]

This hand happened pretty early in the tournament, so no reads on villain. But I already lost a few chips before, which is why I had a shorter stack than most others.
Comments appreciated!

sorry, but when I read the title of this thread i assumed "probably stupid"

if you think that he is position betting on the flop and is tight enough to lay down his junk then checkraise bigger

Since this is lower than a $55, stupid. Save your chips-- they will call u down w/ J high!
