PLO hand

[sdplayerb]

Still unsure sometimes about being potcomitted preflop. But this hand also deals with being up against the chip leader.

99 entrants, down to 22 (9 paid, nice pstars was under 100 for once).
Blinds are 150/300 and we are 7 handed.

I have 6365 in chips and am around 11th.

In the previous hand I hit A high straight on the turn with no flush draw and no pairs and got the biggest stack to move in. he had two pair, but J on the river gave him A high str also to split it. (trying to give more info)
Big stack has 29K. He is playing basically every hand calling or raising PF.

UTG+1 calls, big stack makes it 900 (is utg+2)
fold to me in the SB with Ac Kc Kd 2h.

What do you do?

results/thoughts in my reply.

KK isn't much, but with the A figured unlikely he had AA, plus I had the flush draw.
I came over the top for the max (3000 to 4200).
He raised the rest of the way and flips over:
Jd 8s 5d 9h

I was a 3-2 favorite, which is pretty large preflop in omaha hi.
He was getting 8-5 on his play actually.

and A and J hit the flop. He got two pairs on the turn and filled on the river.

So my questions then are:
1. Do you really want to make a move like i did committing your self when having 20x the BB? Or should I try playing it after the flop which I have been doing very well?

2. When a huge stack, anytime you are getting 3-2 or better, should you just call with anything since you can never be too dominated preflop?

Thanks
