I ran into such a maniac again to day. First, i see him shove 200 bb UTG with A4. Later, I see him shoving KQ for 70bb, which he wins against AJ. One hand later, He 3bets me allin while i have AKs. I call, he shows QQ and the board fills up with 5 blanks.
How should i play those guy's? Some seem to be shoving with Gut shots or midpair kind of hands. I know i probably should sit to their left, and play a lot of hands against them, but as soon as such a guy luckboxes against me, i feel the tilt coming, so i just quit
