We'll have a new banner in a week or so to hang in The Grindstone Cafe. Perhaps we should become the Lyndonville Chess and Film Society..........

Queen vs. Two Rook Endgame? Who Should Win?

That's what occurred last night in a game between David Paulson and me. Due to a mistake in recording the game, I stopped at the point in the pgn below. After perhaps another 20 or so moves, we agreed to a draw in a situation where White was up a pawn, but Black's Queen could essentially check the White King, not in perpetual check, but pretty much into infinity or until the 50 move rule or a three position repeat occurred. A good, very draining game--I slept until 10am this morning.
Robert and Bill Storz had a good long game that they adjourned---shades of years past, although there was no sealed move.

Nakamura seems to have worn down Magnus to a draw. Some chess players might call this a swindle.............
