The TB generator takes the en passant rule into account when generating the TBs, but it does not store ep positions in the generated TB file. So the probing code needs to handle ep with a bit of care.


In RuyDos I just disable looking up a position in EGTB if an en-passant capture is possible. I don't think there are any downsides to doing this, and it was easier than figuring out how to pass the en-passant information correctly to Fathom.
