If TBs make all the difference, then this really is a matter of endgame ability. Maybe someone can give us evals with and without TBs to see what difference it makes.
I'm going to do that very thing. I have a couple of M.2 drives and just received a NVMe PCIe 4.0 drive. I plan on testing how much of a difference the speed of the drive makes when using 5, 6, and 7-man TB. On my current drives when using 7-man TB's the max requests per second is somewhere around 7,000-8,000. This slows down processing to about 40-45 Mnps. The new drive has twice the r/w speed and 3 times the IOPS speed. We'll see if this makes any difference. If it does, I may buy a couple more and make them into a striped array. If not, I'll buy 3 more of the cheaper drives and put them on a raid card.

In the mean time I'll run test without TB's.

Are you sure this is better than the other move? I'm worried that Jim's last comment lured you into false confidence. :o

Oh, good. It'll be very interesting to see.

Wrong destination, according to Komodo at depth 48:

19...Rb7 (-1.32)
19...Rb8 (-1.21)
19...Rb5 (-1.14)

Will now switch to MultiPV = 1, in order to obtain deeper searches.

Comments in this game have barely made any difference in my analysis methods, move choices, or move times. I've already decided what to do depending on certain conditions, and just use the engine to see what conditions appear.

For the record, I saw these two possibilities as equal in my analysis. That's why I decided to wait instead of pondering when the response was taking a while.

And I didn't move until one was clearly better than the other. But it's possible that if one wins by force, that the other does as well.

Jim, have you played correspondence chess before this game? Just so we know the experience level here.

I've only played some games lasting days, nothing as long as here.
