My Lord... it's impossible.

It is impossible.

How could I lose this game !

Computer's analysis said that I had 59+ points of advantage in the end of the game.

Really that kind of losses could cause the psychological trauma.

Shame on my head... shame, shame, shame. ))

Now I see... how easy I could win.

Even two times during the game.

And I notice... I am in the state of panic sometimes... I get very nervious... when I have the such huge advantage in the game.

Do you feel the the same... time by time ?

Or do you keep cold-bloodness in the similar situations to mine ?

It's interesting.

Oh, dear. That is so painful! When I have the advantage, I am always scared I will blunder it away, and then I do… Must get rid of emotion…!

That knight sitting there in the centre half the game cruelled you, I'd say. Neutralised a lot of your potential tactics. I offer no commentary on the endgame, just condolences... 

72. Qa3?? Not quite how you're supposed to win queen vs. pawn. Instead,

72. Qc3+ Kb1 Force the king to hide in front of the pawn, then bring your king closer. 

73. Kf2 Ka2 74. Qc4+ Keep giving checks to get your queen in a good position. 

Ka3 75. Qc2 Ka2 76. Qa4+ Kb1 Now the king has to hide in front of the pawn, so bring your king closer. 

77. Ke2 M3 1-0

Were you in time trouble?

I  did an exercise for myself: 

I have a Queen, stockfish at maximum level has some pawns, challenge stockfish to a BULLET (!) match, with 1 minute... It's annoyingly hard sometimes, depending on which pawns he has and how advanced they are.

Does anyone know if it's possible to challenge Stockfish to a match with a clock on chess.com?

On lichess it is possible...

Work on it this way is very good. I never have issues in these won positions anymore

Play against the engine found in Computer in Play found at the left side of your screen if you're using the website. In the app you'll find it in Play Computer. Then you set the mode to Custom which will give you options on how the game will be played like the time control of the game.

It not your fault you Did not know the theory about king and pawn on the seventh vs king and queen endgame this is just something that does not occur frequently. But this now show you need to update your endgame theory so sober up and get back to studying. Wish you luck on your next tricky theoretical endgame.

Like I said this is just theory and I would won this blindfolded.

I think most 2000+ players would win this. You don't have to see some mate in 10+. The idea is very simple and not that uncommon. You make the king block the pawn, so that you got a move to bring the king closer. This reminds me that in a similar endgame where the pawn is on the c-file and there are no other pawns on the board it is actually a draw.

At least now you know how to fight against that advanced pawn - unless it's a Bishop's Pawn

Nope, this is a basic win for 1600+. You just have to force the king (with checks) to step in front of his pawn, then march your King a square closer to the pawn. You just repeat the process until your King is close enough to win the pawn. Very important but not very difficult endgame.

The way to win this endgame is to make sure your opponent king sits on the promotion Square then use the extra tempo to bring your king closer to the pawn sooner or later your king will be so close that you will suffocate his king and checkmate him all you have to worry about is threefold repetition and draw by stalemate which does not look likely in this position.

Same for if the pawn is on a rook-file.

To elaborate: with e.g. a black King on a1 and a Pawn on c2, the white Queen can't take that Pawn without immobilizing the black King. So, stalemate tricks 

I'd even say 1300+. 2000+ is streching it by alot. 

It's not very common but it does happen, especially with time trouble! In bullet it happens more.

@korotky_trinity check out my suggestion on a practical training method that worked for me, because I assume you were in severe time trouble even if it was rapid... So my method is practical for training for these situations

again, there is a technical aspect of pinning the pawn, checking the king, threatening to take the pawn when the king is away from it,  and bringing your king in... but the thing is to know this automatically to be able to preform it under time pressure. 

Yeah, in retrospect I stretched it way too much.

Actually this is part of the endgame lesson #4 or maybe #5 for beginners.

It is the very first examnple at the Queen Endings chapter of Keres' "Practical Chess Endings", and white's method is very far away from being rocket science..
