Is Bd4 stronger than Rd6 ?
rn2r1q1/p5k1/2p2bp1/1p4p1/2P5/4B1PQ/5PK1/3R3R w - - bm Bd4;
Is this not a Transposition?

Not clear to me that either move wins. I analyzed the position after both key moves were made and then the key position.
The d3+ move has a better score, but it sure look hard to make progress. Maybe a draw. And Rf8 has an unconvincing score that seems to be tending back towards zero. I guess that a very long and deep analysis would be needed to determine which move is best.

Yes, same conclusion from me 1.Bd4 and 1.Rd6 are transpositions. And Rd6 is not so hard to find.
I'll take this one out.
Thanks for your help !

Not clear to me that either move wins. I analyzed the position after both key moves were made and then the key position.
The d3+ move has a better score, but it sure look hard to make progress. Maybe a draw. And Rf8 has an unconvincing score that seems to be tending back towards zero. I guess that a very long and deep analysis would be needed to determine which move is best.

Louis, which engine did you use ? after 1...Rf8, 2.Bxb5 seems a lot stronger than 2.Be6.

BTW, 1...d3+ can be found for deep reasons or shallow reasons. Probably not a good test position.

Thanks !

Cfish-dev. Yes, now it sees 2. Bxb5, and 1...Rf8 has a much lower score.

This has been happening often lately---Cfish/Stockfish completely missing things even at very high depth, at least when MultiPV > 1. Strange.
