How computers can equalize a lost position so easily?

I started very well but the engine slowly equalized. Each move that I did was wrong somehow and I cannot improve my advantage, why is so easy for computers to do that? There isn't a "point of no return" for them?

maybe because its rating is 700+ higher than yours

@eclipsR yes, the computer is much stronger then me, what I meant to point out is that after 6. Kxf3 black has a -3.1 advantage, anyone can look to this position and see that blacks is winning. But even not making any mistakes, on move 15 white has already equalized. This tells me that I don't really know how to play the postition, but also, that white despite the disvantage don't have a "point of no return".

Not sure what this "point of no return" business is supposed to mean...but yeah, the way they outplay us like that is because they're much much better than us. ;)

maybe because computers take advantage of any inaccuracy as well? you made a lot till move 15

There are multiple factors that play into this. The main factor is that you were playing an engine as a relatively low rated player. You are at a rating where you will make more than enough blunders for the engine to win from a losing position. Another factor is that the reason why white is losing is that by playing the bongcloud black gets a massive initiative advantage. This is because white wastes their second move by moving their king, also they move their king towards the center so they have to move it back giving another move, they block the bishop and queen, they create a target. Etc. These disadvantages compound to put white in a losing position. BUT ONLY IF YOU TAKE ADVANTAGE OF KE2. To do this you have to develop quickly, open up the center, and attack. The advantage that black had disappeared because black blundered and was too slow. The abstract advantage disappeared the more moves black made letting white fix their position. That is the problem with abstract advantages like initiative, they are the easiest to mess up.

@MrPushwood @Akarsh_2010 Although this might not be a dead lost postion on move 6, since the advantage relies on the exposed king, I am thinking in the kind of positions that you cannot return to the game for the win or even to a draw. For example, positions where you lost a queen with non compensation are just lost, cannot be equalized without mistakes by your opponent. At least in this case, the computer keeps improving the position somehow, but as pointed out, I did a lot of imprecisions. Anyways, thanks for the feedback.

You helped white develop it's pieces. Although Bg4+ and Bxf3 is not a mistake I would never play it. Clearly Nf6 and Bf5 is preferable against a BOT and if f3 comes just don't take and keep developing instead...

Also keep in mind, if you are going against a strong enough opponent like an engine, the ke2 may not be enough of a blunder to lead to checkmate or a massive material advantage but if after ke2 you apply pressure and play soundly you will maintain the advantage and win a few pawns, and get a positional advantage carrying you through the game. Which if you can get to a position where you are up a few pawns with the king still stuck in the center, then you should be golden.

I guess no GM would win a Blitz game against an unleashed engine, with or without Ke2.

Nakamura lost day 10 years ago given the odds of one move and f-pawn...
