Since March 2019, we have generated 39.8 million games for 2 years and 2 months (AlphaZero has generated 24 million games).
We would like to thank everyone who has cooperated in generating games, and those who have reported bugs and played with.
AobaZero is estimated to be 154 Elo weaker than AlphaZero (377 Elo in Sente(Black), 86 Elo in Gote(White), see below).
From only Shogi rule, it has rediscovered most of the Castles and Openings that Shogi players often use.
Confirmed Castles : Yagura, Gangi, Mino, High Mino, Silver Crown, Left Mino,
Central House, Right King, Yagura Anaguma
Confirmed Openings : Double Wing Attack, Side Pawn Capture, Side Pawn Capture Aono Style,
Bishop Exchange Climbing Silver, Bishop Exchange Rushing Silver,
Bishop Exchange Reclining Silver, Gote 4th File Rook,
Yagura Waki System, Twisting Rook
In Sente, it does not play Ranging Rook. But in Gote, it preferred to play 4th File Rook.
It does not play orthodox Anaguma(78 Gold, 79 Gold), but plays Yagura Anaguma(78 Gold, 67 Gold).
It haven't found a variety of Ranging Rook(Central Rook, 3rd File Rook, etc).
The latest playing style is the immediately hitting static Rook party, which prefers Double Wing Attack and Bishop Exchange, which are similar to AlphaZero's published 100 games.
The advantages are an evaluation of the delicate arrangement of pieces in the early stages, and an evaluation of the possibility of Entering King.
Especially with other software opponents, there are many declaration wins by Entering King. For example, against elmo(WCSC27), 97% of Sente wins are declaration wins.
The weaknesses are missing some tactical moves in end-game, and overlooking long distance Rook and Bishop control.
