Interesting $10+1 hand

[gumpzilla]

Some background. The opponent to my left has established himself as a bona fide maniac. Four times in level one he open pushed, with basically a full starting stack of chips, with such powerhouses as 42, JTs, Q9o, etc. He did this a couple more times and didn't show along the way. For the most part, he either does this or limps or calls somebody else's bet. He minraised a couple of times PF.

Now, the last two hands that the action has gotten to him with no raise he's opened with a more standard 3-4 BB raise. He saw a flop in one instance and instapushed.

SB pushes. I am getting just under 1.5:1.

Thoughts?
