Hi Tere Man,
It's best to totally ignore anything anyone says after they have
lost a game of chess. I've found on here an apology follows a day or
two later without any reply from me.
Also it's perhaps a good idea to keep it out of the main forum,
now this wee episode has been shared it will make it all the harder
for it to blow over. (If it ever will).
You missed a better trade off here.
You played 17...f6 but 17....Nxf2 18 Bxf2 Rxd1+ 19Kxd1 Nxf2+ 20.Ke1 NxR
is trading a Knight and Rook for a Bishop and Two Rooks.
A simple combo. You reacted to his threat on g7.
Look at your threats first, if you can see nothing on then (and only then)
do you consider what he is up to. (and if it's not mate then ignore it and
threaten something bigger).
You are always attacking in chess even when you are defending.
And if you are attacking, then you are not defending.
Here is me in an OTB game from 1983.
I ignore a Rook going with check, I see my threat to his King is a
bigger trophy than a mere undeveloped Rook.
And as for the check....
....I've been checked before, and I'll get checked again...checks never hurt anyone.
