Wow! usually see 2 rooks win against 1 queen

play4fun64

Black's king is not safe.. And white has passed pawns. 33. Rx b7 is the killer move.

Most engine games are not really fun. This one is the exception.

play4fun64

Another Thriller!

65 moves! that was insane!!!

play4fun64

It's rapid 10/3 so they don't make perfect moves. It's really WILD and black looks like winning.

It isn't a Pirc. Wonder what made the tool think it was a Pirc? That opening isn't anything.

I suppose the first two moves but a Pirc has g6 on move 3. This was a Polish Defence.

The ECO classify it Pirc without g6

Optimissed

ECO is wrong. Can't help that. There's no such thing.

play4fun64

It's alright if ECO and me are wrong. Just enjoy the game. You can't argue that game is Beautiful.

If anything, it's a Delayed Polish.

Read this:

"Hooper and Whyld gave a distinct formal definition, 1.d4 d6 2.e4 Nf6 3.Nc3 g6, permuting White's first two moves, although they qualified the definition by remarking that 1.e4 d6 could also transpose to the Pirc.[6] The presence or absence of Black's third move in the Pirc is reported differently, according to the source;[7] with the pawn move 3...g6, Black prepares to fianchetto the king's bishop to g7. Paul van der Sterren therefore described 3...g6 as "the defining move of the Pirc Defence" because the development of the bishop to g7 "creates the same sort of positional tension as the King's Indian Defence".[8]"

That's correct. Without g6, d6 and Nf6 are transpositional moves.

OK I looked at the rest of the game. Looks like one of mine really. Two advanced, connected passed pawns and a queen should always win against a pair of rooks but it was alright.

Ok. I don't have the book but I take your words at full face value. I thought it's a Pirc because Droidfish classified it as one. At the bottom of picture.

Of course, it's going by the first two moves only, whereas the Pirc requires three to define it. Bird's opening, the English opening etc require one move. Queen's Gambit and King's Gambit require two, Italian and Spanish games require three moves to define them etc etc. Grob is one move. Polish Opening is one move. Same with Sicilian and French but I don't think Caro-Kann can be said to be defined after one move because c6 is so transpositional and can go into the Slav, the Pirc, a delayed Polish kind of thing as we've seen etc. It was certainly a double edged game though, up to the point where white managed to achieve the highly mobile pair of pawns.
