Test set from TCEC15 superfinal between Lc0-Sf

[Ferdy]

Save the pos and its actual move as bm in epd from the games if:
1. The side to move in the position wins the game.
2. The score_cp <= 300 in the move comment from actual game.
3. bestmove of Stockfish 10 at 1 sec of analysis and actual move in the game are not the same. (Same move would most likely mean easy bestmove).
4. Not a book move

Thanks for this collection ferd. Will check and study this positions now.

I wonder about the following, if the alternative moves are not as good or better:

I am sure there are good alternative to some of those epd's. The test is mainly to see which engines at short movetime would get more hits from some positions in tcec 15 superfinal match. The epd's are from long TC with good hardware which most users could not duplicate, and the engine under test is only at 5s/pos. The talented NN is at number 2 so far

Thanks for this collection ferd. Will check and study this positions now.

The positions from these games are indeed very interesting. A good time to review one's opening repertoire and also see the ideas of each move.

Thanks. It seems pretty clear than Nd3 is better.
That one is counter-intuitive for me. (IOW, Nb3 looks really obvious)
