O-O {[%emt 0:00:03] =} dxe5 $6 {[%emt 0:00:03] [%c_effect e5;square;e5;type;Inaccuracy;persistent;true] Black solves the central tension too early and without reason. Note that if White takes on d6 (exd6), the pawn d4 remains isolated. However, if Black takes on e5 (dxe5), White gets rid of the need to protect the pawn d4. The d-file will be opened early, while White has some space advantage and better development. Note also that Black's bishop f8 must go to e7 anyway to guard the threat Ng5.} ({Better is} 8... Nb6 {=}) (8... Be7 {= is a standard opening theory.}) 9. dxe5 {[%emt 0:00:05]} Be7 {[%emt 0:00:02]} 10.

Rd1 {[%emt 0:00:29] ± As the d-file is open now, White can develop with a tempo.} Qc7 {[%emt 0:00:09] Black's queen is active on c7. Now, White has to be careful concerning the threats on the c-file and the threat against the pawn e5. If Black has enough time to attack the e5-pawn, the move Rf1-d1 turns out to be a mistake, if the retreat Rd1-e1 is required.} (11... Bd7 {± is not better.}) 12. Bd3 {[%emt 0:00:03] White is waiting Black to castle to attack the pawn h7.} (12. Bb3 {with the idea} Na5 13. Bc2 {± is also possible. However, White wanted to immediately put the bishop on the active position on the b1-h7 diagonal.}) 12... Nb4 {[%emt 0:01:00]} 13. Be4 {[%emt 0:00:03] Now, White's bishop targets both flanks of the opponent.} ({The chess engine Stockfish 16.1 suggests here} 13. Nc3 Nxd3 14. Rxd3 {± But White does not want to get rid of one's light-squared bishop in the open position. Particularly, White avoids getting rid of the bishop pair, if Black still has it.}) 13... N4d5 $2 {[%emt 0:00:05] [%c_effect d5;square;d5;type;Mistake;persistent;true] Note that because of the early exchange 8...dxe5?! 9 dxe5, in the present position Black missed the opportunity 13...d5!} ({Both players missed the simplifying move} 13...

Nc3 $6 {[%emt 0:00:45] [%c_effect c3;square;c3;type;Inaccuracy;persistent;true] White makes natural moves, ending one's development.} ({Stronger is} 15. Na3 {?}) (15. Rc1 {?}) 15... Nxc3 {[%emt 0:00:19]} 16. Bxc3 {[%emt 0:00:05]} Bc6 {[%emt 0:00:04] Black succeeds in solving the problem of the development of one's light-squared bishop.} 17. Rac1 {[%emt 0:00:27] White has finished one's development and the position of Black's queen on c7 is exposed. Black needs 3 or 4 moves to overcome all of one's development issues.} O-O $2 {[%emt 0:01:30] [%c_effect g8;square;g8;type;Mistake;persistent;true]} ({Safer is} 17... Bxe4 18. Qxe4 Qc6 19.

Ba5 $1 {[%emt 0:02:00] ± [%c_effect a5;square;a5;type;GreatFind;persistent;true] Now, Black is pinned both along the diagonal a5-d8 and the file c1-c8. The knight b6 and the bishop c6 are pinned. White's bishop e4 is still active towards both flanks.} Rfd8 {[%emt 0:00:28]} ({Perhaps the best solution was to give away a pawn:} 18... Qb8 19. Bxc6 bxc6 20. Rxc6 {±}) 19. Nd4 $1 {[%emt 0:01:00] ± [%c_effect d4;square;d4;type;GreatFind;persistent;true] After all other moves, Black immediartely almost equalises. Black has only one missing tempo to solve one's opening problems.} Rac8 $2 {[%emt 0:02:43] [%c_effect c8;square;c8;type;Mistake;persistent;true] This naturally looking move completes Black's development. But it is a mistake. The rook turns out to be a target on c8.} (19... Bg5 $1 {[%c_effect g5;square;g5;type;GreatFind;persistent;true]} 20. Rc3 Bf4 $1 {[%c_effect f4;square;f4;type;GreatFind;persistent;true] was a good idea.} 21. Nxc6 Rxd1+ 22. Qxd1 bxc6 23. Bxc6 $2 {[%c_effect c6;square;c6;type;Mistake;persistent;true] White's rook is now defended on c3 and not in c1.
