Good luck.

You don't need to post diagrams so frequently. I'm okay with every 3 to 4 moves, depending on how complicated it is.

It's possible in certain circumstances to gambit a go-between cleanly. Under normal circumstances, I have a feeling that it may be possible, but the lines are ridiculously complex. So much time spent trying to make it work. I get close, but it always fails somehow. I've taken a break from any attempts to find a solution. This shape is not one of the special ones which allow you to gambit a go-between.

I'm not sure if anything else must be mentioned here related to the rules.
