Set Mining in PLO8

This was a fascinating PLO8 table. Lot's of raising with A2XX, never figured out what markerdarker needed to raise but believe he bought in for $25 at least 6 times and also may have tilted Big Gray. The Chirio I have seen on FullTilt before but don't have good handle on his style but am quite sure he makes somewhat steady profit.

Glad set held up.
Was fascinated I was called by A2 + gutshot and A3 + bottom pair.

This morning looked at hand on cardplayer.coms Omaha Hands Calculator. The Chirio had a 38% expected return on hand as he was 54% to hit low and 20% to get high (I guess due to gutshot + backdoor flush).
