stunning come-from-behind victory

To begin with, in this game I'm showing here, I know I should have lost. I was looking to make a sacrifice at move 13 ... Nh5 followed by 14 ... Nxg3. But my sacrifice was pre-empted when my opponent promptly showed me the error of my way: I had set myself up for a pawn fork. Arg. About ten moves later, with 27 ... h5, it looks like I blundered. Really I think it's just a loss of the exchange (and a pawn Embarassed). But the two/three together put me down one whole rook. I decided to "soldier on" despite being down so much material. Then, ten moves after that, my opponent blundered fatally with 37 Kf1. I'd like to say his blunder was due to the pressure I applied but I don't think that's accurate. Looking over the game afterward, however, I didn't find much in the way of good moves available to him at that point (instead of 37 Kf1). Maybe someone here will find what we missed (and share it with the rest of us here). Finally, I'd like to say I'm sure I've benefitted from chess.com's Tactics Trainer; in particular, my attack beginning with 37 ... Qf6 and continuing with 39 ... Qxb2+ in this game is evidence of exactly that.

 

After the game, I decided to "continue playing against the computer" from the position at resignation. I was able to win, but it took 40 moves to do so. I suspect NN was disappointed with himself after 37 Kf1 and didn't want to go on.

Nice game, sorry I don't have enough time to make an analysis...what did the chess.com computer say?

I haven't submitted this game yet for chess.com computer analysis (or any other type of computer analysis, for that matter).

You really should, it can be very helpful especially if you have been constantly playing an opening line that you made up for instance it will correct you and give a move for your opponent that would give them a better position or a gain in material.

Here's what I found from the (chess.com) computer analysis:

For Black:

5 inaccuracies

1 mistake

2 blunders

My (as Black) blunders were at moves 13 and 28, as I had suspected. The computer likes 13 ... Qd7 better than 13 ... Nh5?? (score = 1.44). The line given by the computer beginning with 13 ... Qd7 ends with "a moderate advantage for Black". Instead of 28 ... hxg4?? (score = 5.5), the computer recommends 28 ... Qxg6. At the end of the computer-generated line beginning 28 ... Qxg6, "White has a slight advantage".

Mistakes by White allowed me back into the game. Instead of 32 f5?, for instance, the computer recommends 32 Re2 (score = 6.23). Instead of 35 Nf3? the computer recommends 35 Qf3 (score = 5.01). 

After 36 ... bxc5 the computer scores the game at 3.66.

After 37 Kf1?? the computer scores the game at -1, and after 38 Rf2?? the computer scores the game at -5.04. The computer prefers 37 Qg4 Qg3+ 38 Qxg3 Nxg3 39 Ree1 Ne4 40 Kg2 Rf6 41 Rf1 Ra6 42 a3 Rg6+ 43 Kh3 a5 44 Rc2 a4 45 Kh4 Rf6 when "White has a decisive advantage". After 37 Kf1?? the computer prefers 38 Kg1 Rxf3 39 Rf1 Rxf1+ 40 Qxf1 Ng3 41 Qxf6 Nxe2+ 42 Kf2 gxf6 43 Kxe2 Kf7 44 Kd3 f5 45 g3 c4+ 46 Kd4 Ke6 47 a4 when "Black has a moderate advantage".
