Practise: BUG+1
Every marked open cell has two notes except one with 1/6/8. Which one of those three candidates has an odd count and must be placed?
This is a real BUG+1 endgame. The prepared notes cover every open cell: all but one are pairs; the marked 1/6/8 pivot forces 8.

Your turn first
Check the prepared open-cell notes. Which cell has three candidates 1/6/8 while every other marked cell has two?
Remember
BUG+1 appears when every open cell is bivalue except one 1/6/8 cell. The candidate with odd count 3 is forced: 8.
