Play 51 RO of previous post; need deeper RO

A few days ago someone posted this position; sorry could not find the message.

I did a 0-ply RO and as you can see, three candidate plays are very close.

Wondering what the correct play is. If the big iron crew has time, would be great to see a good RO.

Thanks.

The score (after 0 games) is: gnubg 0, leo 0

Move number 4: leo to play 51

gnubg	148
leo	160
