Winning with 32 pieces on the board.

[Roger de Coverly]

Here's a recent rapid play game by Nigel Short as White in which his opponent resigns with all the pieces still on the board. (The Queen is trapped). The opening is vaguely reminiscent of ideas used by Mike Basman with the extended fianchetto created by playing g4, h3 and e3.

The position at move 20 is a candidate for the occasional series of "worst move on the board".

Close, but no cigar. I think 20...Qg3 probably just about edges it.

I think 20...Qg3 probably just about edges it.

The worst plausible move then. Putting Queens en prise is generally noticeable. Allowing them to be trapped, particularly by responding to a "nothing move" like Bf1 then less so.

Yes, "worst plausible move on the board" is a more accurate title for this genre - though admittedly not as snappy
