Aside from needing a phone

That is a huge one for me. Yes, I have a phone. But I spend most of my waking time in front of a desktop or laptop. With Whatsapp, Telegram or Signal I can read and write messages from the computer, copy/paste text to the documents I am writing, and send and download files. SMS are more limited.

Black could always move the rook to a1 before promoting the pawn. It forces a trade, but still leaves black with an advantage.

This is too slow. After 1... Bxf4 2. Ng2/Kh1/Kg1 Ra1, white can simply take the pawn for free with 3. Rxb2, and black loses all the advantage.

If white moves his knight to g2, check with the bishop at g3 also gets him another pawn and opens up the king’s defenses a little.

Trading a bishop for a pawn (one pawn that wasn't passed and only in the third rank) is not a very good deal, and black makes no progress towards promoting. Also, in endgames, king activity tends to be more important that king safety.

after 1... Bxf4

White can play either 2.Ng2, 2.Kh1 or 2.Kg1

which in all cases stop the threat of 2... b1=Q because now 3. Rxb1 is available

The move Bb4 has two functions: clearing the way for a possible discovered check in the second rank, and shielding the promotion square from white rook. On the other hand, the move Bxf4 only clears the way for the discovered check, but doesn't protect b1, so promotion is no longer possible.

This is the position after 1... Bb4:

after 2. Kh1:

and after 2... b1=Q#

How are you proposing that 3. Rxb1 is going to happen?

[–] jalda@sopuli.xyz 1 points 2 years ago (7 children)

No. After 1... Bb4 2. Kh1 b1=Q#, white rook can't take the queen because its path is blocked by the bishop in b4. In fact, it is checkmate.
