Worst move on the board

Post by Roger de Coverly » Mon Jan 15, 2018 11:15 pm

The now closed Streatham blog would run an occasional series on this.

Here's an example from a League game this evening.


Black to play and find a "normal" move that loses instantly.

The position should be recognisable as having arisen from the "Short" variation in the Advance Caro.

Black played Qb6, and presumably white responded with Ba5?

Yes.

A database search suggests the blunder has the merit of being original.

However, ...Qa5 would have been a worse move.

On reading this I spent a good 3 seconds wondering why white's Ba5 deserved the question mark :?

Yes, but that is trivially obvious. Though it does mean that Qb6??? still isn't the ABSOLUTELY worst move, as in your former series.

No mention of the final match score in the fixture which generated this curiosity? :)
