More Details: • A strength test is done (before starting the new rating): Results / Games Another new strength test (regarding the current rating): Results / Games One new test more for this tour (16CPU+PonderON): Standings / Games Btw, I've run some similar strength tests too (about 3 years ago): Results In short, I was wondering about the power/quality of the current games And sometimes, higher kN/s values do not mean better performance !) As you know, 16 cores has much higher kN/s values than 8 cores, but... Here definetely 'Ponder ON' is played a BIG role...impressive results! In other words, it all depends on our conditions and there is one true: MP + Ponder ON seems to be the best/most powerful way of testing • All engines are played each other with 8 cores (per side) + Ponder ON And it seems (e.g many of the Top MP engines up to 8 cores) to be safe... • Due to some engine bugs ... mainly Arena, plus Fritz GUI is used too E.g Andscacs, Booot, Ginkgo, Hannibal crashes/suffers under FritzGUI Even Hannibal 1.7 crashes under Arena and ShredderClassic GUIs too Of course, not sure exactly what can be the reason...but it's clear that: The mentioned chess engines are not so stable as MP + Ponder ON • Unfortunately Ginkgo 1.96 is taken out (due to often time forfeits)
