20...Kc7

We've reached move 20. I think white is better and has some winning chances but I think it is likely black will hold this.

Up to you, do you want a draw or to play on?

Hello:

Twenty first moves is a good point to paste a PGN and a diagram:



[d]4r2r/ppkn2pp/2pb1n1B/5B2/7P/2N3P1/PPP5/2KR3R w - - 3 21

I did a brief analysis with SF 11. I write below a summary from depth 25 to depth 32, where the seven best moves did not change their ranks:

Code: Select all

SF 11, 2 cores, Multi PV = 7.

4r2r/ppkn2pp/2pb1n1B/5B2/7P/2N3P1/PPP5/2KR3R w - - 3 21

                  Move 1   Move 2   Move 3   Move 4   Move 5   Move 6   Move 7

Evals are quite stable. I do not write the proposed moves for obvious reasons, the game is still ongoing. I also consider that post evals is not harmful since anyone can run (even deeper) analysis, including the players.

It would be nice to compare the evals at this point of the game against the evals after 1. e4 e5 2. Nf3 f5.

------------

Latvian Gambit is an opening that has always caught me, it is very wild and irrational. I have been following the game with great interest since its start.

OTOH, I would not play the Latvian Gambit with black pieces even in a must-win situation, of course! There are other options for me.
