I think we can consider the draw offer as part of the move which means it wasn't a tie (yet):
29. b4 (ArticMine, XMRpromotions)
29. b4, offer draw (smooth)
I'm willing to change my vote to just b4 without the offer of a draw if needed.
I agree with smooth that the draw offer should be part of the move.
There is actually a FIDE rule that kind of supports this: "If a player makes a draw offer before making their move, the opponent can ask them to make their move before deciding."
https://en.wikipedia.org/wiki/Draw_by_agreementWith this requirement we also avoid the situation where a team silent on an draw offer discussion can might have one team member vote for the leading move at 23:58UTC and add a draw offer.
I do think the game is likely to end in a draw but there are still some chances for both sides in my opinion. I vote to keep playing for now but will reconsider offering a draw if it becomes clear that neither side can make progress.
