Hi All,
STS 15 is now available for download.
Consists of carefully selected 100 test positions on "Avoid pointless exchange"
The test suite deals with the decision to exchange or not, with all of the positions involving queen. These are the cases when the exchange is best avoided because the side retaining the queen is more aggressive , and therefore prefers to have the major piece's presence in order to conduct the attack on the flank or even in the center.
It may even be the case when keeping the queen on the board may prove beneficial to the side, in terms of better co-ordination with other pieces.
Furthermore, the positional imbalance arising out of these positions suggests that it is best to avoid pointless exchange.
Tests engine's knowledge on Exchanging, Piece Activity, Positional imbalance and Mobility.

Thank you to both of you for sharing these very interesting test sets.
I will consider these positions in my evaluation tuner training positions.

You're welcome.
My impression is that it is certainly more challenging compared to rest others in the series.

Thanks to you both. A short test to test the scaling, Stockfish seems again to scale better than Houdini on this test too, as in previous STS 1-14:
Code: Select all
1 second/postiotion
H4 64/100
SF030414 61/100
1 minute/postiotion
H4 87/100
SF030414 92/100
