It is advantageous for White, NOT to connect the single stone in the top left corner.
Black 5 correct ? Probably, check next revision. White's capture after Atari is worth 7 points in this area. 
If Black captures, he looses 2 points in Gote, White will get some additional points in the centre thereafter.]

Probably makes no difference; three points more in the centre compensated by the loss of the endgame in the top right.]
