Fun hand right? haha!
It's certainly difficult to assess what is the optimal play in this weird spot.
At the time, he knew that I knew he was blind, so if I shoved all in he will probably make the call if he has been dealt a half decent hand.
However in hindsight I much prefer making sure he sees a flop. If he managed to make a pair or a draw he's going to be in a very tricky situation and will probably pay off at least a few bets.
Personally I like to look as weak as possible here by flat calling. The weaker I look the more likely he will be to pay me off if he makes a pair.
However at the time I re-shoved all in, hoping for him to wake up with a half decent hand and make a call with his big stack. He looked at his cards and chuckled as he flipped over his 84o.
