test positions for weak playing engines only

[Henk]

Do you know a list of fens which are positions any weak playing engine should be able to solve ?

[d] rn1qkb1r/pp2pppp/5n2/3p1b2/3P4/2N1P3/PP3PPP/R1BQKBNR w KQkq - 0 1

I tried the first one of "CCR one hour test" but Skipper thinks Nf3 is better than Qb3.

WAC (win at chess) is good for weak engines, may be too easy for you ?
EPD here (300 positions) : https://chessprogramming.wikispaces.com ... D%20Wacnew

Results for SF (10 positions are not found in less than 1 sec, may be they are cooked ? ) : http://www.talkchess.com/forum/viewtopi ... =&start=10

Skipper cannot find d5 as well in BK.02 (Bratko-Kopec test). It finds Re1

I will have a look.

Not too easy. For instance Skipper can't solve WAC.002:

[d] 8/7p/5k2/5p2/p1p2P2/Pr1pPK2/1P1R3P/8 b - -

WAC.002 seems not very easy. How does Skipper on the others ?

I first have to write a function that test them in a row. Testing them one by one is not that practical. WAC 001,003,004 no problem for Skipper.

[Also Skipper does not show PV all the time. So I have to fix that too if I have time.]

Timing for SF are here : http://www.talkchess.com/forum/viewtopi ... 902#614902 .
May be focuse positions where SF solve in less than 1 second.

WAC #2 is known to be difficult. Null move can create problems in solving this.
