\"A slight miscalculation.\" (Gukesh)
1. d2d4  1... d7d5  2. c2c4  2... e7e6  3. g1f3  3... g8f6  4. g2g3 \"He does not play the Catalan that often.\" (Gukesh) 4... f8b4  5. b1c3  5... d5c4  6. f1g2  6... e8g8  7. e1g1  7... b8c6  8. a2a3  8... b4e7  9. e2e4 [%cal de2e4][%c_arrow e2e4;keyPressed;none;from;e2;opacity;0.8;to;e4;persistent;false] This sharp gambit line is a common concept for the Catalan and the QGA and was apparently prepared in depth by Praggnanandhaa. \"I checked, but I could not remember. It is a very dangerous line, and this is why I was taking so much time.\" (Gukesh) 9... a7a6  10. c1e3  10... b7b5  11. d1e2 White connects the rooks in preparation for a powerful break. 11... c8b7  12. a1d1  12... c6a5  13. d4d5 There White goes $1 13... e6d5  14. e4e5 After opening the d-file, White shifts into full kingside mode. 14... f6e8  15. e5e6 [%csl Rg8][%cal Gf7e6,de5e6][%c_arrow e5e6;keyPressed;none;from;e5;opacity;0.8;to;e6;persistent;false][%c_highlight e6;keyPressed;none;opacity;0.8;square;e6;persistent;false] Opening up the opponent's king. All of this was blitzed out, as confident as you can imagine. Gukesh was already heavily behind on the clock, taken by surprise, and it seemed as though Praggnanandhaa would score a crushing victory straight out of the opening. Black thought that he had two moves, and the one that he chose turned out to be a novelty. 15... f7f5 \"After this move he started thinking, which means f7-f5 is not a great move.\" (Gukesh) 16. f3e5 A logical follow-up. White immediately shifts his knight into close proximity to the black king. 16... e8f6  17. e2c2 [%c_effect c2;square;c2;type;Interesting;persistent;true] \"This move I completely missed, and it is quite interesting if not best at all.\" (Gukesh) 17... c7c6 [%c_effect c6;square;c6;type;Interesting;persistent;true] Giving back a pawn in order to secure the center and gain a tempo for the kingside defense. 18. c2f5
