After removing Wasp games (crashed out) the scores are: Fire +16, DefenChess +13, RubiChess +7, Vajolet +5, Pedone +3, Nemorino Winter 0, PeSTO Gull -1, Texel -2, Minic Demolito -4, iCE -8, Igel -9, Pirarucu -15, Wasp DQ.
Fire, DefenChess, RubiChess and Vajolet advance to league 1.The race for 4th place was only determined in the last round. Fire returns to league 1 with the previous AB version, DefenChess advances for the second time this season.
Minic, Demolito, iCE, Igel, Pirarucu and Wasp relegate out of league 2. Five engines that advanced from qualification go back down, Wasp crashed out. Minic crashed in a won position against Nemorino, without this crash both would have had the same score as Texel, not sure which engine would have relegated then. Winter and PeSTO managed to stay in league 2 after advancing from qualification. Gull survived another season, perhaps the next one will be its last.
The 4 promoting engines are planned to join KomodoMCTS, Laser, Ethereal, Xiphos, Chiron, Andscacs, Fizbo, ChessBrain, Booot, rofChafe and Arasan in league 1. According to the current season 17 engine page Jonny needs a stable update to play in the league. Other engines may fail testing, as we have seen in league 2. More engines may yet promote from league 2, the list will be finalized in a few days.
The GPU league 1 is getting closer and there has been no update about the GPU hardware planned for this season, or the candidate engines.
Notable games
Game 138, DefenChess - Vajolet: Vajolet gave a knight for pawns and attacked the white king. DefenChess defended its exposed king and slowly reduced to a RBN vs RB position, then advanced passers forced Vajolet to give its bishop and the game was over.
Game 149, RubiChess - Pirarucu: Pirarucu's king was exposed in the center, and its king side pieces were stuck. RubiChess gave material and attacked, winning in 22 moves.
Game 152, Vajolet - Nemorino: Vajolet gave a knight to open the queen side and expose the black king. Nemorino tried to give back material, the game reduced to a QR vs QBN position. Advancing passers and the exposed king were enough to give Vajolet the win.
Game 157, Pirarucu - Wasp: The game reached an unusual QB vs RNN imbalance, white with no pawns to black's six. The white pieces were very strong and Wasp gave material to reduce to a QR vs RBN with 5 pawns. Pirarucu used mating threats to capture the knight and was strong enough to win. Too bad Wasp already crashed out and this first win for Pirarucu will not be part of the final score.
Game 159, PeSTO - Demolito: Demolito gave a rook for a bishop and opened the position, PeSTO's king was exposed but it had an advancd passer. PeSTO gave its queen and promoted the pawn, it used back-rank threats to capture a piece and win.
Scores after 20 rounds: Fire +11, DefenChess +9, RubiChess +7, Pedone +6, Vajolet +5, Nemorino +1, PeSTO 0, Winter Gull -1, Texel -2, iCE Minic -4, Demolito -5, Igel -9, Pirarucu -13, Wasp DQ. Wasp crashed for the third time and is disqualified, all its games are ignored. The top 5 engines are in the race for 4 promotion spots. Three of the bottom 6 engines still have a chance of surviving,
Game 180, Demolito - Igel: Demolito gave two knights for a rook and its major pieces were less effective with many pawns on the board. Igel pushed pawns on the king side, Demolito gave material to try to stop them, enough for a black win.
Game 184, Texel - Pedone: Texel was up a pawn in a RB vs RN position. It gradually improved its position and then captured two more pawns for the win. Pedone's first loss in the league.
Scores after 24 rounds: Fire +13, DefenChess +10, RubiChess +7, Pedone Vajolet +5, Nemorino +1, Winter 0, PeSTO Gull Texel -1, Minic -4, iCE Demolito -6, Igel -9, Pirarucu -13, Wasp DQ. Pedone and Vajolet are tied in 4th place after Pedone lost its first game. At the bottom Demolito and iCE are 2.5 points away from survival, Minic still has a small chance but will lose tiebreaks due to its early crash. Only 6 rounds to go.
Game 197, Demolito - Nemorino: Demolito was up a rook for a bishop and Nemorino's bishop pair was not enough as compensation. Demolito created a passer in a RN vs BB position, Nemorino had to lose material to stop it.
Game 198, Gull - Vajolet: Gull played better in a RBB vs RBN position, it used a pawn majority on the queen side to queen a pawn while Vajolet captured a bishop and the remaining 5 pawns. Gull stopped the black pawns to win.
Game 213, Fire - Vajolet: The game reached a RBN vs RBN position, Fire's eval increased very slowly. It took more than 50 moves to capture a pawn, another 20 moves to reduce to a winning RB vs RN ending two pawns up.
Game 214, Demolito - Pedone: Demolito went up a pawn with an advanced passer early in the game. While Pedone focused on blocking the passer Demolito developed a deadly attack on the black king. Just before the game was adjudicated Pedone crashed.
Scores after 27 rounds: Fire +14, DefenChess +11, RubiChess +7, Pedone +5, Vajolet +3, PeSTO Nemorino 0, Winter Gull Texel -1, Minic -3, Demolito -4, iCE -7, Igel -9, Pirarucu -14, Wasp DQ. Three rounds to go. Vajolet is a point away from 4th place Pedone, still with a chance to promote, and with a tiebreak advantage after Pedone crashed. Minic and Demolito improved their chances of survival, but since they both have games against Wasp effectively they only have two games left to close the gap. iCE has only a theoretical chance of survival at this stage.
Game 220, Pedone - Fire: Fire went a pawn up late in the game in a QRN vs QRN position. After a long shuffle Fire exchanged queens, it took 30 more moves to reduce to a winning knight ending.
After round 28 Pedone (+4) is only 0.5 points ahead of Vajolet (+3). There is no change at the bottom of the table, Demolito had a material advantage against Texel but couldn't convert.
Game 225, Igel - Minic: Igel gave a knight for 4 pawns and created 2 advanced passers. Minic was busy trying to stop the passers, it captured one but lost material to stop the other and the game was over.
Game 227, iCE - Nemorino: iCE was better in a QRR vs QRR position, it reduced to a rook ending a pawn up and reached a tablebase win. First win for iCE in the league.
Game 229, Winter - Pedone: Winter was up a rook for a knight, its king exposed in the center was Pedone's compensation. Winter gave the material back and reduced to a RB vs RB position with white a pawn up. After exchanging rooks the extra pawn was enough for a win.
After round 29 Vajolet (+4) overtakes Pedone (+3), the last round will determine which of them will finish 4th. The situation at the bottom is: Winter 0, PeSTO Nemorino Gull -1, Texel -2, Minic Demolito -4. Demolito's last game is against Wasp so it cannot escape relegation. Minic needs a win to reach Texel, and only if Texel crashes does Minic have a chance in the tiebreak (not sure what happens then, it is very close).
In round 30 Minic drew and relegated, Pedone drew and lost the chance to promote, then Vajolet won and increased the gap to a point.
