On the bubble ATo to poss blind steal. Good play?

[retro69]

Hiya and thanks for reading. I want to try and find out if im being too aggressive on the bubble here, I do find im finishing 4th too often in these 50,30,20 tourneys. The villan was tight early on but recently became more active with a couple of all in bets post flop. Is this a reasonable play or am i losing money here? Thanks.

you say he is being aggressive postflop, but what about preflop? If you've seen him raising a lot more shorthanded, this is a fine play. You do have a little bit of folding equity and if he's been stealing a lot of blinds you have no reason to believe your not ahead here.
