OK, I admit your E7xE6 moves kills the blue win for this position, since it takes too long for the blue sergeant to reach the flag. Nice find! I posted a new position in the Training forum where I think blue can win no matter red's defense.
I also admit (and have so from the beginning) that these positions are contrived. I just want to find out where the differences occur between 5-times, 3-times or even 2-times two-squares rules.
Thanks. I am curious too but more about situations that are (more) realistic. But maybe there are not such situations. Some people claimed to me in the past that in certain situations its different (between 3 times and 5 times) but I never saw a valid example.
