there was only 2 but in that scenario vote 3 would not have mattered.
Me vs. All

So do I take it right that the rule is just that a move is played immediately after it gets a second vote? E.g. if 5 posters suggest 5 different moves, then a 6th poster seconds one of those moves, or if one of those 5 changes their mind and revotes for a move of one of the peers, it's played, isn't it? Or does a move have to gain >50% of all (3+) votes to be played? It's gonna be slow in the latter case.
Wait, I thought there have been only 2 votes on the 2nd move.
Anyway, if it's played, then I vote for 3... b6 obv, gogogo QID!
