i assumed with only me as a blind left he was tryin to steal the blinds so i came over the top for all my chips. i never assumed that a) he would actually have a decent hand (i assumed he would try to get some value for it, so he wouldnt wanna waste it) and b) that he would call off all his chips with AJ
am i wrong in making this play?
should i have put him on a strong hand?

u have 20xBB, no need to be makign crazy plays like this! Just let get in your share of steals.

This is not the stage of the tournament for these kind of shenanigans, wait until the bubble or something then put a guy to a desision for all of his chips with something like this when he is more likely to fold.

There are awlays better opportunities then this one..... No need to get agressive in a spot were your hand is pretty vulnerable.
