I wasn’t entirely happy with my solution to this in the previous post (a 2-point loss for orange), though that line has the advantage of being more or less a forced game: if orange wishes to lose by only 2 points, violet really has to go along & can’t win by any more. Very useful for tournament play.
BUT: I’m not happy with that orange T5 kiss move, since it seems to me obvious that (1) it’s an unnecessary bit of finesse (since violet will not block that corner immediately) and (2) since it’s a close game & violet is really starved for spots for the 1 and i2 pieces, it’s foolish to give him those spots for free.
So, consider these screenshots as part of my continued exploration of this game, diverging at the point where I played T5 in the earlier game. I won’t give blow-by-blow lists of moves, as it’s getting late in the evening & they are mostly obvious (especially since the opening moves are identical to Study in XF Rubik #1), but I will provide comments.
One-point win for orange. Moves from L5-F on: I4-N / T4-L5 / N-I4 / V5-I3 and the rest is packing. Violet N is bad as it’s the only good block for the top — the V5 leaves an I3 hole, enough for orange to eke out a win.
I realized that the orange N in the previous game is the wrong way round, as orange needs to threaten to grab I3 AND i2 on top. So this line shows that violet can get a 3-point win this way. (If orange N is turned the right way then it’s a 2-point win for violet… I haven’t got a screen cap, but will post it later.)
So here’s another variant on the first game, with orange N in the “right” position, & orange deciding to stop the I5 (which I think is a mistake…. orange has a nice i2-1-I4 series off violet I5, & violet can’t make a really big block in bottom right off the I5 anyway). 3-point loss for orange.
A big win for orange if violet continues to circle. Violet Z5 is a mistake–should be Z4 (1 less point for violet, 2 less for orange) but anyway, this is not good for violet — the leak off the violet L5 isn’t enough to do much of anything.
This time I used L5 not F, & the results are interesting (though I have to see what it’d be like if violet blocked in top right rather than playing I4. A close win for orange, even despite the space-eating I5. (I would have to check if blocking the I5 move with P or Z4 and letting violet get I3 on top is better for orange.)
The moves from L5 on: L5-L5 / I4-T4 / T4-N / N-I3 / I5-V5 / the rest is packing.
OK, so take it from here, folks…. I want to know where these games can be improved from either side.
