in this real game black has two squares threatening mate, but both separately protected. he plays a very nice ... Nd2 + to deflect both and white resigns...



... why is this a grave error?

edit: damn i forgot the thread title again

Bxd2?

yes, of course... mate square inaccessible because queen is pinned. far too easy for this forum! 🙂

it's from the pan american championship in 1963.. i often wonder why high flite players resign in ambiguous positions, but usually rea\lise that's because of my own relative shallow game knowledge. nice to know that big brains are human.

here's another:
white to play (in an adjourned position) posts Re6, looking at rook swap, and then Re6+, winning two more pawns...



black opens the envelope, resigns. again, what has he missed?

Well, after White plays RxR, Black can simply reply ...g3 and the pawn Queens.

correct, big dogg.. simply refusing the rook swap and there is a forced win.
