The following is an extract of a game i played with Tom Morgan, friend from
Exeter on chess.com using my smartphone which I should never have won
in a million years, my opponent had a serious advantage until move 44.Nf3
after which I had a serious advantage until i almost blew it with the
horrendous 51.g6 (i swear i never saw the e pawn) anyhow, I used a
computer to auto-evaluate the game afterwards, being unwell and feeling
lazy, you can find the analysis here

anyhow my question is about the computer analysis, i wonder if someone
stronger can point out why the computer line is better, for i did roughly see
it but considered it suicide,



The computer gave this line which i simply fail either to understand or see
why its in any way better,

I am not an expert, so I have the following question. If white just moves away the rook?

Oh and I can't answer the original question.

It looks like black was simply lost there and the 'suicidal' computer analysis was an attempt to make the best of a bad situation. The idea of ...Bc8 to save the Rg5 is a non-starter due to the fork Nxc6+. As Ponderable said, white could have simply moved the R away on move 2 (to a2, or the Houdini-preferred f2) and the R on g5 will fall.

Ok many thanks it was simply the computers way of making the best of a bad situation, now I understand.

I put in another game for auto evaluation by the silicon beast, this time against Lee Gibson, it was a Caro Kann, after my move 1...c6 the computer states, inaccuracy, the best move is 1...e6

this game contained no errors for me, but a single blunder, hard to think that a check on an exposed king could be a blunder, but it is,



in the game Lee blundered immediately with

I'm surprised it got that far and didn't say 'blunder' once you'd put your username in.
