My brother knew I was going after the knight for rook, with the rook pin. Qxc6 was bait earlier.

What was played...
We should of recorded all the moves of this game.
Thanks,

I can't explain the Fail Low scores that Rainbow Serpent is having at the moment. Like that +0.80-- score, these scores are obviously far too low and seem to happen if a side branch of the PV gets chosen. In this case 2.Qxc6 which was not yet in the PV.
I get a better result now, but probably that is only because the Fail Lows happen to be a bit higher, so no switching of the first move occurred. I will try to investigate where this is coming from, it is a bit embarassing...
