List of all 400 legal openings in 2 plies (by # of master games)

I continue the statistical representation of moves in colours. Pirc defense #10 is both W-edged and statistically suboptimal.

I've started to indicate the acuteness:

The Scandinavian and Alekhine defenses are the first two 1-acute openings in the list.

There is only 1 best / optimal move.

From's gambit #55 is also 1-acute.

Current status: 56 openings, 490+ master games. The Anglo-Lithuanian opening #56 is 1-acute with the unique optimal continuation 2. d4.

Now with Benko: Dutch 1. g3 f5 the list contains 57 openings.

Thanks, buddy!

Current status: 58 openings, 450+ master games.

And now 59 openings with 400+ games.

#60 St. George defense is added.

Now #60 is Réti: Polish and #61 is St. George.

Catalan is an opening in 5 plies but what do U wanna know?

#62 Sokolsky: Indian is added with evaluations and suggested moves.

Solkolsky: Indian is now #63 while Mieses: QP jumped at place #62.

Current status: 64 openings with 250+ master games.

#65 Réti: Slav 1. Nf3 c6 is added.

#66 is Reversed Nimzo 1. Nc3 e5.
