[Event "Onlind Rapid (15 min)"] [Site "?"] [Date "2023.??.??"] [Round "?"] [White "igrac23"] [Black "black"] [Result "1-0"] [ECO "C00"] [PlyCount "49"] [EventDate "2023.??.??"] [EventType "rapid"] 1. e4 e6 2. d4 d5 3. e5 c5 4. c3 Qb6 5. Nf3 Nc6 6. a3 c4 {One of standard ideas in such positions. Black had abandoned the ideas of pressure against d4 with possible opening of c file in appropriate moment for the benefit of blocking the queen side in order to go for 0-0-0.} 7. Nbd2 Na5 {Now blockade must be maintained, otherwise white has b2-b3.} 8. Be2 Bd7 9. O-O Nb3 $6 {Each exchange at blocking square (b3 in this case) actually makes such blockade less efficient.} (9... Be7) (9... Nh6) 10. Nxb3 Ba4 11. Nfd2 Ne7 12. Qe1 cxb3 (12... Bxb3 13. Nxb3 Qxb3 14. Bd1 $1 {After queen retreat and Ra1-b1 blockade on b3 would be over. Not only that, white bishop would be strong once it would be set on c2.}) 13. Nf3 Nc6 (13... Bb5 14. Bxb5+ Qxb5 15. a4 Qb6 $16 {Not only that black could not maintain blockade on the queen side but from this moment it would just be question when b3 pawn would fall down leaving black clear pawn down.}) 14. Bd3 Na5 {May we notice how much resources and time black had used just to keep queen side under control (fixed pawn structure).} 15. Qe2 Qc6 (15... a6 $5 {With idea of Bb5 with exchange of bishops.}) 16. Bg5 $5 {With white pawn chain fixed on dark squares idea was to keep option of exchange this 'potentially problematic' bishop for black's one which at certain time had to go to e7. Of course black could play h6 followed by g5 but it would not be clear if such pawn structure on king side would be in his favour.} Nc4 17. Rfb1 {With idea Nf3-d2.} Qc7 {It became clear that black was out of useful moves.} 18. Nd2 Nxd2 19. Bxd2 a6 20. Rf1 $5 Qb6 21. Bg5 $6 a5 (21... Bb5 22. c4 dxc4 23. Bxc4 {Position would be getting open, with black king still on e8.}) 22. f4 Bc6 23. f5 Bd7 24. fxe6 Bxe6 $4 {Perhaps Qxe6 would provide certain resistance. Now black was lost.} (24... fxe6 $4 25. Qh5+ g6 26. Qxg6+ hxg6 27. Bxg6#) 25. Bb5+ {Black resigned. After Be6-d7, white would just take Bb5-d7 with Rf1-f7 and black position would be hopeless.} 1-0
