1. d2d4  1... g8f6  2. c2c4  2... e7e6  3. g2g3  3... d7d5  4. g1f3  4... h7h6 A mysterious move that seeks a slightly different piece development than what we normally see against the Catalan Opening. 5. f1g2  5... f8d6 The bishop is developed on this unusual square, without Black needing to worry about the move Bc1-g5, if I understood correctly the idea of the move h7-h6. 6. b1c3  6... b8c6 Another curious move, since Black normally doesn't like to place the knight in front of the c-pawn in queen's pawn structures. The main idea here is to exchange on c4 and then play e6-e5, when Black's development starts to make sense. 7. e1g1  7... e8g8  8. c3b5 [%c_effect b5;square;b5;type;Inaccuracy;persistent;true] A rare and not very good move. 8.b3 is more common. 8... d5c4  9. d1c2  9... a7a6 The best way to achieve a good position. 10. b5d6  10... c7d6  11. c2c4  11... c8d7 Although White has the pair of bishops, Black's position is pleasant, with easy development and good control of the central squares. 12. c1d2 A new move. 12... c6e7 [%c_effect e7;square;e7;type;GreatFind;persistent;true] An excellent move, freeing the c6-square for the bishop. 13. a2a4  13... d7c6  14. c4d3  14... c6e4  15. d3a3  15... d8d7  16. d2b4  16... e7f5  17. f1d1  17... f8d8  18. a1c1  18... a8c8  19. b4c3  19... b7b5  20. a4b5  20... d7b5 [%c_effect b5;square;b5;type;Inaccuracy;persistent;true] This is a positional mistake, as this is not the pawn formation that Black is looking for. 21. g2f1 [%c_effect f1;square;f1;type;GreatFind;persistent;true] White prepares Nd2 followed by e3 or f3-e4. The a6-pawn becomes a target. 21... b5d7 [%c_effect d7;square;d7;type;Mistake;persistent;true] 22. f3d2 [%c_effect d2;square;d2;type;GreatFind;persistent;true] 22... e4b7  23. c3a5  23... c8c1  24. d1c1  24... d8c8  25. c1c8  25... d7c8  26. a3c3 White tries to exchange queens and go to an endgame in which the presence of the bishop pair guarantees lasting pressure. 26... c8d7  27. e2e3  27... d7a4 [%c_effect a4;square;a4;type;Mistake;persistent;true] This activity backfires since it allows White's queen to create more dangerous threats. 28. b2b3 [%c_effect b3;square;b3;type;Mistake;persistent;true] 28... a4a2  29. c3c7  29... b7d5  30. g3g4 [%c_effect g4;square;g4;type;Interesting;persistent;true] A courageous move. 30... f6g4  31. e3e4 This is the idea of the previous move. 31... f5d4 [%c_effect d4;square;d4;type;Mistake;persistent;true] A miscalculation that decides the game. 32. e4d5  32... d4f3  33. g1g2  33... f3d2  34. f1d3 The attack on the king by the bishop pair is too strong. The a5-bishop is currently out of play, but is ready to go to c3 if needed. 34... f7f5  35. d5e6  35... g4e3 [%c_effect e3;square;e3;type;GreatFind;persistent;true] 36. f2e3  36... d2e4  37. d3c2  37... g8h7  38. e6e7  38... e4c5 [%c_effect c5;square;c5;type;GreatFind;persistent;true] 39. e7e8q  39... a2c2  40. g2h3  40... c2d3 This is the most interesting position in the whole game. Three queens on the board and Black is threatening perpetual check with 41...Qf1+. There's only one winning move. 41. h3h4 [%c_effect h4;square;h4;type;Brilliant;persistent;true] Paikidze finds it. The king moves away before the check. 41... d3c2  42. c7d6 There's no perpetual check and the game is over. 42... f5f4  43. d6d2  43... c2f5  44. e3f4  44... c5e4  45. e8e4 The simplest method to convert the advantage. 45... f5e4  46. h4g3  46... e4g6  47. g3f2
