Thanks Jim for the compile and for giving the above information.

So.... Why did we go from 09.980 to 1.2?

Thanks for the new version, even if the numbering is kinda odd.
I hope it does well in my tests; I like Doch.

To make things more confusing we went to a different version scheme!

Seriously, the ??.???? format is what I use internally and I never intended to use that for release versions as it's more difficult to remember.

So, 30-60 elo is to be expected.

I think "Offer of Simplification" is greatly improved in Doch 1.2.

I guess the knowledge or code regarding "offer of simplification" or "placing pieces in direction of trade" has been significantly improved upon.

I got many thanks for this and it's appreciated. I am working to deliver more improvements too in (hopefully) the near future with Larry's help.
