Patterns in 960 starting positions III

Kind reader, you may see in part one Patterns in 960-I how to calculate the set of positions with bishops in opposite corners. If we take B = 3 in formula ID = B + 16Q + 96N, we get the next table:

These positions are among the most difficult to unbalance. Both players are forced to play a kind of Reti double fianchetto. Players are forced to move g and b pawns in early moves, this is because I think the most determining factor for an opening strategy is the position of bishops. They are the only pieces that force you to move determined pawns to make they can play.
I will try that, in the starting diagrams of the games, the initial pawn strategy adopted by both players can be seen.
For each Q value I will choose three non bullet games drawn from current site, games between computers and GM tournaments.

Q=0
In this 3+2 game with position#3 black plays very risky from my point of view, changing one bishop and trying to occupy center.
11.Nc5 is also good and a more human move than what SF comments 11.e3.

With position #99 we have this top GM's game from Freestyle chess GOAT 2024.
Caruana takes profit of weak squares in d5 and c3, a plan started in move 11...e4.

Finally, with position #579 we have these two games:
A first one between modules, it is interesting how Stockfish 19 evaluates today this game of his 'elder brother' SF16.
Seeing this game I asked myself what happens if black grabs the f5 pawn in 17th move, 17...Nef5 18.Nf5 Nf5 19.Nf4. I thought for myself, black's pawn structure is solid, I don't see weakness and although black king is in e8 square no attack is on seen. Nevertheless white has a positions where activity of pieces is enough compensation for material. Rudolf Spielmann, author of 'The Art of Sacrifice' (1951), would be happy with such position.

The second one is a very good positional work of young player Praggnanandhaa. His elo does not seem well annotated.
First moves are like Aronian - Caruana game, but the starting position is not the same.
White did not move g pawn until move 24, 15.h3 is incomprehensible for me. module only marks this move as ?!, I would mark it with a '?'
26...Qc3 is a very good move, ignored by module in its comments, that deserves a !

Q=1
In Position #883 1.b4 gives a 0.4 evaluation, one of the highest I could see in this set.
In this position there is an uncomfortable weakness in f7/f2 that forces both players to play very carefully.
For example in this 3+2 game with 1.b4, black plays an interesting 2...Nh6 to have f7 defended and, why not to think about a possible Ng4.
It was a pity the blunder in move 18.

Is these twin games both modules plays very similar. It calls my attention that SF dislikes move 1...c6. They do not look at f7, but to a7 weakness in a very intersing way that I already saw in other positions, Qa3 attacking 'a7' pawn is a queen move like typical Qb3 threatening 'b7' pawn in standard chess.

Q=2
Position #35
During a dinner at Karlsruhe, after a round at grenke open, speaking with editor Arno Nickel he speculated about how would have played FRC Tigran Petrosian, one of the most original styles that never was.
In this game your humble narrator takes an idea from Petrosian's games, changing fianchetto bishop for a knight in c6 to spoil black's pawn structure. Mikhail Tal, astonished after the capture made by the armenian player, commented that he gave the exchange to remove that bishop and Petrosian gave it just for opponent remains with a bad pawn structure. It is what I did in this 3+3 game.
In move 17 I did not play Qa7 because I disliked Bh6 not the move that module suggests.

With position #323 we find the next modules game.
Seing the opening, it is like symmetric english when white takes in d4 with queen. The most impressive for me is how black gives a7 pawn ,it doesn't try to defense it. The human that writes this text would play 4...Qa5, that is not punished by module, a +0,3 after 5.Nc3. It also the very original 5...0-0 6.Nh3. It wants to keep open white great diagonal, as in the game.
In a whole life I would never understand white move 13.Rfe1. No 12.Rc5 Qd6 --+
Last ten moves are a waste of time.

And with position #899 a game from Freestyle Grand Slam KO in Grootbos 2025, Maghsoodloo-Niemann.
White opens black diagonal and closes the white one. You may decide it depending on where is your king. In move 19 it is needed real cold blood to grab h7 pawn, but 19.Nh7 is the best move according our sparky friend. Who dares?

Q=3
Position #531
A position with a twisted symmetry. It's a lucky fact to find two twin 5+5 games between strong players.
First game, spoiled by a blunder, a double early fianchetto against a center attack.

Second game, one normal fianchetto the other amplified fianchetto,
27...d5 with the painful threat 28...d4 followed by Re1 forcing Rb2 and then Nd1

Position #819 a remarkable game from opening to endgame, played in St Louis 2021, 96% of precission for Vachier. I don't know timing but I assume that is rapid.
Both players fight for center since the beginning none of them looking for bishops exchange.
Very interesting the answer suggested by module to first white move 1.e4, 1...g5. Your humble narrator played 1...g6 always.

Q=4
With Position #643 we have a So - Svidler, chess.com World Fischer Random 2019 game. A symmetric opening gives to black a balanced game in the opening, white initiative with 6.Ne5 is not enough. With the same position I chase 5.Ne5 immediatly instead 5.c4

Amazing is the original strategy followed in next game, drawn from position #835, by SF16, against a 'weak' player of only 3000 points Elo. 3.e5 is difficult to play , but the white rook in e1 helps. The gift of a pawn in 9th move adds new surprise. Who could resist to move 8...Qa3 ? Last 20 moves are expendables.

With position #931 we may found this game Nakamura - Fedoseev played in Freestyle Weissenhaus 2025. Original opening and remarkable the evilness of 13.Bd4, with double threat in a7 and Bf2, and SF put a question mark on it. Because evaluation falls from +4 to +2

And with no less interest this other game Firouza - Sindarov from same tournament. It calls my attention 5.g5. White stretegy to control e5 and c6 is very interesting to see.

Q=5

With position #83 a game played by two very strong players, Firouza - Salgado, WRFCC KO 2019. French-Iranian GM develops a classical strategy taking profit, when he leaves a weak d5 square, that is very difficult for black to put a knight blocking.

With position #179 the game Sindarov - Fedoseev , Weissenhaus 2025. A great 16.g5! after the natural black move 15...Kh8?
As a curiosity, in the opening black breaks symmetry with 7...Ne6 instead Nf7.
White player's ranking maybe is not precise.

To finish the blog, after youth comes senior, with position #947, Milov - Hort, played in Mainz, Chess960 WCh (Senior), 2006.
Variation given in move 13...Nfe4, 14Nf4 Nh3 is impossible for a human to calculate such deviation to overload white queen. It is impossible to calculate maybe, nevertheless possible to enjoy of the complexity of variation. I disagree with module tag of 12.e4?! I would prefer !?
