Unstacking the bloated midpoint seems more of a priority than making the deuce point or slotting the three.

Anchoring at the head of the potential prime with Bar/23 24/23 looks natural but leaves us in a very static position with virtually no ways to develop.

The only way to get some winning chances is to prepare undermining the timing of white's prime to come by trying to block some high points for later silver point escapism; that's why the 2 is imo best invested into 13/11.

Off topic maybe, but has anyone noticed how the spoilers don't work in the "most recent posts" part of the front page?

Yep, which is another reason why I think the whole spoiler thing is a waste of time.  Unless you're consulting a bot it's just one person's opinion and there's nothing "spoiling" about that.  But stog wants us to use it for whatever reason, so we do.

it simply contributes towards or allows you to make an unaffected choice first, using your own criteria without the conscious or subconscious influence of other opinions, which can then be read before you 'remove your vote' and re vote for the sensible option you somehow missed

and yes the spoiler fails in the front page block sometimes; sometimes it doesn't mind  ;)

This is worth analysing..no one has picked what gnu considers the best move..I found this quite interesting..

I'd have played the herd's move. I'm guessing it doesn't like it because the outfield blot isn't threatening to do anything really strong (given I am so far up the herd's board) and is therefore a bit of a liability if I start a good attack going. Second choice for me would be the anchor, but I see GNU 3-ply does something unexpected...  :unsure:

XG thinks that splitting is a bigger priority than unstacking, but not by that much.  The Herd's play is only a small error.  Anchoring is a blunder.
