Daily Chess Puzzle

Today’s problem was seen on Twitter.

As is my custom, I only say which side is to play: and not giving an idea if the move wins or otherwise, unless on occasion I think signposting would be helpful. Instead, the problems are posed with the instruction to decide what you would play, as in a game.

Black to play

Raja v Adhiban, Ahmedabad, 10/2/2020

Solution

1…Rg2+!!

If I saw this move when playing blitz, maybe I would play it; but if I saw it in classical chess, I doubt I would have confidence in my ability to see all the variations or to play it on intuition.

A fantastic move.

2 Kg2[] Ng6

My engines are saying 3 Rg1 or 3 Nd4 are the best moves, which shows that Black is very much better. White instead played the more human move 3 Kh2 and after 3…Nf4 4 Rg1 seeking to play 5 Rg8+; Adhiban won a fine game.
