If we play b5! and Martin plays Na5 (doesn't go for the Knight exchange), then we can play Nb6 or Nf4. But, if we play Nb6, he can play Bb2, and a move later play e5 attacking our Drunken Bishop.
We're screwed if we let that happen. At least if our Knight is on f4, we can fork his queen and Drunken Bishop, and then take his DB with tempo. (check)
So, we're trying a gambit to see if he'll bite, exchange the Knights early, which would be good for us.
Can't be sure if these are good, yet, because the "Knight" is young, but we would have a solid position if he goes to a5 with his Knight.
I just get a feeling… could be wrong, though.
I'm worried about the moment he brings his other Bishop out. Then… LOOK OUT! With our Knight on f4, it would make perfect sense to take his DB on e2 if it tries something premature.
I don't have the answers yet. These Drunken Bishops make analysis next to impossible.
That's why I'm picking just one move, and I look at all the "roads" that flow from it, until it either turns into a super highway, or becomes strewn with potholes.
Martin is just one person, and so he can only look so far down a road before he gives up or tires out.
But we're the World! We can delegate analysis to various members, divide and conquer the current puzzle position to be solved, really assess things in detail, and not leave anything overlooked.
Here's an example of how I do it for the one move of b5! (I set up a Notes Page in my computer, and start making the forward outlook until I know what's up.)
b5
So, as you can see, it is very tedious, but no stone is left unturned.
Part of this whole Variant "experiment", imho, is to see if we can really harness the World of chess players.
Btw, really difficult to post this, so ignore my formatting. Much easier on my Mac Notes.
