  1. d4 e6 2. Nf3 f5 3. g3 (3 c4 was the choice in 1501 games at the ChessBaseDataBase, resulting in a 54% outcome for white. The 1239 games in which 3 g3 was played is the second most often played move, but the result has been better at 56% for white. Stockfish 14 @depth 49 and SF 220521 @depth 51 will play 3 Bf4, which has seen action in only 173 games. I kid you not…Even more astounding is that the result has been an incredible 62%!) 3…Nf6 4. Bg2 (SF and Komodo play 4 c4) 4…d5 5. O-O (SF goes with 5 c4) 5…Bd6 6. c4 c6 7. b3 (SF says Ne5) 7…Qe7 8. Ne5 (In almost one half of the games played [844] 8 Bb2 has been the move played even though it has only scored 51%. Go figure… One Komodo program prefers 8 Nc3 [45 games; 57%], while another prefers 8 Qc2 [67 games; 57%]. Then there is Houdini…who would play 8 Ne5, as has been played in 253 games while scoring a fantastic 60% against the highest rated opposition!) 8…O-O (Komodo castles but SF prefers 8…Nbd7) 9. Bb2 (Fritz plays the game move but Komodo plays 9 Bf4) 9…Bd7 (SF 14 plays 9…b6. Deep Fritz plays 9…Nbd7) 10. Nd2 Be8 (Komodo and Deep Fritz 13 play this but SF 8 plays 10…Rd8) 11. Ndf3 (The most often played move and the choice of Komodo, but SF 14 plays 11 Nd3) 11…Bh5 (SF 12 @depth 38 plays 11…Bg6) 12. Nd3 (SF 8 plays the game move but SF 13 @depth 35 plays 12 Ne1 a NEW MOVE, and a TN if and when it is played over the board against a human opponent…) 12…Nbd7 13. Nfe5 g5 (Fritz likes 13…Bc7; SF 8 plays 13…Ba3, both of which will be a TN if and when…)

13…g5 was a surprising choice by Mr. Aaron and certainly must say something about the kind of player who would fire the g-pawn salvo at his esteemed Grandmaster opponent. A player does not make such a move in an attempt to draw. Things got interesting quickly after GM Shabba pushing his e-pawn only one square in lieu of two on move twenty. Then after 20…gxf4 Shabba should probably taken the pawn with his knight with 21 Nxf4. It was at this moment Deepak could have taken control of the game by playing 21…Nh5, but played the retrograde and limp-writsted 21…Ne8 giving the advantage to Shabba. Only a couple of moves later Shabba played a limp-wristed move himself when easing the Bishop back to f1. Deepak answered by taking the pawn on f4, which was the reddest move possible according to the Bomb; big advantage to Shabba. After the exchanges on f4 on move 24 the GM had a won game. With all the action taking place on the king side Shabba, for some reason, decided to move his Bishop to a3, tossing away his advantage. For the next several moves there was punching and counter punching with the game staying about even, Steven, until the GM played 32 h3, again a BRIGHT RED move, the kind of move GM Yasser Seriwan would call a “howler” and it was time to turn out the lights because the party was over…
