{ [#] An instructive queen and pawn endgame position. } { [%evp 0,18,112,113,108,114,108,117,112,107,116,117,109,329,330,334,410,379,
147,147,218] }
35... Qxd7 36. a6 { A good start. This move fixes the a7-pawn as a weakness and secures
the b7-square for the queen. } 36... Kh7 37. e4 { This
deviates and improves on the actual game, which was drawn. White is looking to
trade queens by force to win the king and pawn ending. } { [%cal Rc5f5,Rf5d7,Rf5h7] } 37... Kg8 38. g3 { Black's
goal is to force a perpetual check. Therefore, White aims to have complete
control over the access points to the king to prevent checks. } 38... f6 { Following a
theme from the main game. } 39. Kg2 Kh8 40. h4 { It is difficult to suggest a
move for Black. } 40... Qf7 (40... Kg8 41. Qd5+ { [%cal Rd5d7,Rd5g8] }) 41. Qc8+ Kh7 42. Qb7 { White has reached the ideal position
and the win will follow. } { [%csl Rf7][%cal Rb7a7,Rb7h7,Gb7g2] } 42... Kg8 43. Qxf7+ Kxf7 44. h5 { White fixes the kingside structure and will utilize the pawn
majority to get the win. } { [%cal Gf2f4,Gg2f3,Gf3e3,Re4e5] } 1/2-1/2
