His sizing is 10 times what he would have 'wanted' to make it, so its likely that he misclicked and added an extra 5 when typing it out. Or he was angleshooting and pretending to do that when it was actually deliberate and trying to get you to stack off light. However with your hand it was probably going in anyway so don't feel too hard done by, just a cooler.

i made exactly that thinking about extra 5 to the standard 3 bet sizing and that was why i went all in. it was too big stack to push all in for AK but i wasnt thinking that i was playing coinflip, i just thought he wold fold or he would be behind.

Raise 75 BB ... lol mini raise.

Really interesting spot, seems like a decent chance it could be an angle but at the same time it doesn't make a ton of sense to angle in that spot with AA when you fold super often after opening BTN, so could very well be a misclick that worked in villain's favor!
