After about four hours, the Obsidian says (-3.27) 43 Rd2 Rxd2 44 Bxd2

It is not clear if the Obsidian's expected score or PV can be retrieved after a search finishes.

The TC search has been running since very early this morning and it's already at 13 ply so I'm going to end the search early this time for speed of play. The selected move hasn't changed at any point during the day....

The TC plays Rxd2 with a score of 3.3

The expected continuation is a bit lost

Bxd2 Kg7
Bc1

So for the moment the TC doesn't really see a plan for the Obsidian, with the King move taking care of some potential pesky checking moves.

Rd8

The TC got through 11 ply really quickly then stalled at the beginnings of it's 12 ply search. It's not showing any continuation again so it's obviously found something that's disturbed it.

Score was 3.3
