An interesting UR opener for two steps...

Quote:
UR(58)r16c23 psuedo-cell(14) -(4=8)r1c9-(8=1)r3c8-(1=5)r3c1; r3c1=5
remote pair(48); r7c3<>4


More remote pairs! - are these the new acceptable face of xy-chains?

Same UR as MM. I didn't notice Remote Pairs but did use simple coloring on 4 to finish it off.
