so played this hand today in my session, now afterwards i was thinking about if this is a standard call OTR or should i just consider a fold when the hand was played this way? because i think all his flushes he would play this way, at least his nuts but maybe not the worse ones he could maybe consider e check sometimes OTR here with a baby flush?
since im kinda new to PLO and but have been playin holdem for a while, do i find this spot unclear after ive actully played the hand, so a help on the way, what assumptions and so on i should do here cause i find this a clear insta call since im also getting 2:1 on the call
