Novikov vs Shabalov: Leningrad Dutch

This game was played, or maybe “battled” would be a better word, in the same round as the previous game, which meant following two games closely while keeping an eye on the other three. When the Bishop’s opening “truth” and a main line Leningrad Dutch appeared on the board my first thought was…

which was followed by, “Oh happy day!” something for which I was known to say by certain students when they would, like a blind squirrel, find an acorn move.

  1. d4 f5 2. g3 Nf6 3. Bg2 g6 4. Nf3 Bg7 (According to 365Chess at this point we have the A81 Dutch defence) 5. c4 (After this move it becomes the A87 Dutch, Leningrad, main variation) 5…O-O 6. O-O d6 7. Nc3 c6 8. Rb1 (At the Chess baseDatabase one finds Komodo14 @depth 40 has a preference for this move, but Stockfish 220621 @depth 45 likes 8 Be3, a move found in only two games at the CBDB. Then there is Stockfish110521, going way down to @depth 55, playing 8 Qc2) 8…a5 (Komodo 10 likes 8…Ne4; Komodo 13 prefers 8…Na6, but Stockfish 13 going deeper than the two Dragons, would play the move chosen by Shabba Dabba Do, and so should YOU!) 9. b3 (Komodo 13.02 @depth 39 plays 9 Be3, as does Stockfish 13 @depth 55. After 9…Ng4 the Dragon would drop back with 10 Bd2; the Fish would advance into black territory with 10 Bg5, or at least that is what one sees at the CBDB. The thing is 9 Be3 has yet to be attempted in a game! There is not even one example of the move having been played in either the CBDB or 365Chess!) 9…Na6 (SF 151120 @depth 52 would play 9…Ne4. There is only one game in the CBDB with 9…Ne4:

  1. Bb2 (SF 11 @depth 37 plays the move played in the game, but let it run longer and go deeper to depth 47 and it changes its way of ‘puting, switching to 10 d5. There are only four examples of the move at the CBDB. 10 Bb2 has been played 21 times. Komodo, not to be outdone, would play 10 Be3, a Theoretical Novelty) 10…Rb8 (The Fish & Dragon concur, 10…Qc7 is THE move. The game move is not found in the CBDB, but there are two examples found at 365Chess:
