about the double attack test

[philip]

Hello.

I just took that double attack test #1 and I think there is something inacurrate there.

Question 15 is this:

 

and the answer marked as correct is:

 

very nice and sufficent to win, but i think this is even better:

 

 

because if black captures the bishop, there is a family check with Ng5+ and if not, white can still carry out the Qxe4 idea.

 

cheers, Philip

 

P.S. I think I have found another flaw there, Question 20 is: "what is the worst move now?" and on marking the blunder-move, I get a wrong there.

Also, in Question 10 the Move marked as correct is Bxc3, and there is no such move on the board, its gotta be Bxc6

I'm not sure Bxf7+ is such a good idea as black can then play Kd7, and Qxe4 Nxe4, Bd5 is not as good as before: the knight on c6 is now protected.

Still, it's probably wiser to choose positions where there's only one good move, or create tests where more than one good move is worthy of a correct answer (currently possible with flash software, as all our LOCMAI tests).

I think you're right about the other positions. These tests will be updated sometime this year as they are now outdated.

 

Thanks for reporting this!
