Friday night, we finally got a 6 handed cash game of omaha going down in Southend must be the 2nd time we were playing in 3 years.
We played a round of each PLO - PLO H/L - 6 CARD PLO (High only)
Just wondering what people thought of these hands, for reference we were playing 1/2 and all players sat down with 200 and a few rebuys.
HAND 1
PLO
Hole Cards:

(button)
2 limpers and a check
Flop Cards:

SB: 6
BB: Call
ME: Call (is there anything wrong with this in anyones eyes (im very new to omaha and want to learn) do i try and get heads up with top pair/kicker etc and raise pot or do i call hoping to hit the straight/flush draw and get paid off?
Turn Card:

SB: 15
BB: 35
ME: Call (is this wrong calling with a nut flush draw and up n down straight draw)
SB: Folds
River Card:

(completes my straight and nut flush)
BB: Check (now obviously i guess he is putting me on a flush, and im not getting paid, so at this point the pot is 109, now what kind of bet am I making here to get paid or do i just bet out pot thinking im not getting paid)
ME: 54 (1/2) pot
BB: Folds but shows nut straight, and says "please show the flush"
Have I dont anything wrong here? have i played this wrong? could I have played it any other way? and was I wrong for not showing him the flush?2nd HAND PLO H/LIm still getting used to this game both live and online, so bear with me
