@@andreasmatthies5517 I let both engines think for 300 seconds for every single move. PV stands for Principle Variation. Basically, having it at 7 forces the engines to calculate 7 of the best moves indefinitely. Usually it's set to 1, meaning it will stop looking at all other moves and only continue calculating the one variation it thinks is best.
@@lethallohn I know what PV means, I am the developer of RubiChess. Using a fixed time per move is not very common but okay. Using a PV > 1 for game playing is a no-go! Engines implement very different solutions for calculating more than one PV line, so the quality of the later PV lines may be better in one engine compared to the other but uses a lot more time and so the quality of the played move decreases. Extreme example: One engine could always use the PV=1 algorythm (resulting is best game play) and output random valid lines 2... n without any cost. I'm not saying that it is impossible for Rubi to lose against Stockfish with white. But the conditions of your game are without any value.
@@andreasmatthies5517 So, what you're saying is that Multi PV is different for each engine and won't be an equal playing field. Thanks for letting me know!

Can you please explain, what "Time control 300 Seconds per Move PV 7" means?
