Queen vs two Rooks endings, great practice for human

[Chessqueen]

Next game I tried to Draw against Stockfish playing Black, I had the Queen plus all the pawns versus Stockfish 2 Rooks and f3 pawns odds, but stockfish played first. With just Queen versus 2 Rooks it was a great challenge but Stockfish was too much for me, most of you should try to draw as well I believe that moving my King to 41.Ka6? was a great mistake I should have taken the pawn to draw, but maybe Stockfisk would have won anyway

This was my previous challenge but the f3 pawn is like taking two pawns odds, but without the engine having any other pieces just pawns it should be easy to win, if you include both queens it would be harder to beat any top 4 engines, but I gave Stockfish the first move

This is how I should have played it by taking the pawn instead of 41.Ka6? which was an ending blunder, that I played in less than 10 seconds

Next Game I will try to at least draw, against Stockfish with Stockfish playing without its f3 pawn, since it is only both Queens it should not be that hard to draw, this is a little bit harder to play than versus 2 Rooks as before, I might be wrong, but I feel that if I give myself 15 minutes per game, I should be able to draw. What makes the game much more tactical complicated which benefit the engine is to include more than 2 pieces into the board such as both queens and maybe a knight for both sides or both queens and maybe a bishop to both sides I I strongly believe that any player Not st5onger than 1950 should be able to draw, if their ending knowledge is good with pawns. Most players rated under 2000 should also try this position

I do not give up so easy specially if I came so close from drawing the last time, so I decided to attack from the other wing. I would like to see other players drawing against Stockfish or Dragon 3.1 or 3.2 with this position, it is a great challenge and a great way of practicing endgames, with just both queens the engine will not create too many tactical positions against you, unless you decide to use a Queen and Knight for both, with this same position.
