Hi

Today I had this honor to play against a semi-maniac. Why semi - PF he wasn't too aggro. But whenever I showed weakness on the later streets, he shoved. Especially OTR.
And - when I showed strength OTF+OTT, he usually folded.

I thought that it might be useful for me - if I flop a monster for example. I could "show weakness", and my opponent would shove. Because if I had shoved, he would have folded.

What would be +EV for me to call his shoves OTR? K-high/A-high/mid pair OK? Since his range is so awfully wide, I'm a bit worried to call a shove OTR with a pair of Aces, if he might be holding two pair, 92...

The player's stats:
VP: 100%
PFR: 12%
Call CBET: 75% (kept me honest...)
River bet: 91%

Here are some examples.

Thank you

Why do you raise only 2BB pre flop?

P.S. Your examples are similar.
