! I have to confess that I did not see this move. The following exchanges are forced.

! The open a-line is Black's only possibility. White is a pawn up, and it is a passed pawn. However, only a pair of queens and a pair of knights are on the board, while some of White's pawns are weak.

I did not understand the point of this move, but the chess engines are endorsing it.

Black's idea was Qa8-a4xb5. Also, in some cases, Nc4-d2xe4, or to get close to White's king.

!? Again, White cleverly combines the threats on the kingside with the passed pawn on the queenside. However, from now on, White's king is pretty open to checks, giving Black some additional drawing chances.

?! The chess engine says that better was 36...Qa1=. After the text move, in some variations, White can use the open h-line.

?! The chess engine says that 37...Qa5! 38 g5 Qe1+= was better.

! Now, Black is in serious trouble. White not only has an extra pawn - a passed pawn P/b5 on the queenside -, but White also threatens to intrude on Black's kingside with the move 39 Qf6+. The problem is that White threatens to take the pawn P/g6 with a check. After that, White's queen can return to h5 so that the knight N/d1 is defended again. Black's position is critical.

! A prophylactic move! Now, White's queen has to defend the knight N/d1, which, in turn, is pinned. If White plays with the king, then Black has won a tempo. Of course, not 38...Qc1?? 39 Qf6+ Kh7 40 Qf7+ Kh8 41 Qf8+ Kh7 42 Qh6+ Kg8 43 Qxg6+ Kf8 44 Qh5 Ne3 45 Qf3+ Kg8 46 Qxe3 Qxd1+ 47 Kf2, and White is two pawns up in the queens endgame. 38...Kg8 is Black's only hope.

Together with this move, White sent me a message that I was using the computer. Probably, he kept in mind the chess engine. In that message, my opponent called me insultingly a "looser". On his profile, that player from the US uses the phrase "Canadian idiots". I did not answer the message and blocked my opponent.
