I would just like to add that no engines find correct next move and I have a 12 core,but a bit of brain power will.

After 21...Rc8 22.Qd3 Ra8 white wins with either 23.Bf3 or 23.Bg4

after 21...Qf6 22.Bg4 wins

To anyone who does not understand this line,what I am saying is 14...h4 line is bust.

I would like to say my opponent Ruben spent 8 days looking at this position armed with at least one 12 core looking at this position and then resigned,see game link to a team game in this position,posted.

[NATIONAL12]

Pehaps this link will clarify the position,although it does not make happy reading.

Stockfish switches from h4 to a6, but not quickly:

Yes 14...a6 is a better move.
