Clearly the h6 pawn is undefended. I think the best move for black is to save the h6 pawn by moving to h5. That's the best move for black.
Position of the day- 2.9

No, after 1...h5 then 2.Rg8+ Kf7 3.Rxc8 and the Nf4 is lost (playing 2.Bxf4 actually seems better)
Ok, any candidate moves? How about 1...Nxg6? No, then Black is mated in a few moves after 2.Qxg6+
1...Bxd1 and 1...Ne2+ both seem worthy for analysis; oh shoot, my parents are calling me downstairs. Happy analyzing for me, :/

By the way, my line after 20...Bxd1 continues 23.Qxh6+ Kf5 24.Qh7+ Ke6 25.Qe4+ Kf7 26.Bxf4 Qc6 27.d5 Qf6 28.Be5 with a winning endgame.
And after 20...Ne2+ 21.Kd2, I think Black is stuck :P
Also, after 20...Bd5 21.Qf5, I'mm not sure how Black can continue.

Master Kaina,
Are you sure whites reply to black's first move in your sequence is the best?
why did you rule out the other possible reply?
analyze again, and share your doubts about the other reply keeping the game equal, if there are any.

...after 20...Ne2+ 21.Kd2, I think Black is stuck :P...
I've already taken a look, and I didn't find even a glimmer of hope with White threatening mate in 2.
Hi, in this forum I will post a daily position, asking you to write the evaluation of the position using the tools given in my article, and offer a plan and a move.
Then, together with me, we will discuss the quality of the evaluation, and different ideas from chess that reflect in the position.
Today's position is:
So, analyze opponent threats first, then give a full evaluation, and upon that base a plan and suggest a move.
