OK, so Stockfish considers 14...Bd7 worse than at least three other moves. Still, I can't imagine it's bad enough to cost the game, i.e., the correct evaluation of the position after 14...Bd7 is still 0.00 (=DRAW). On the other hand, take a look at 21...Bb4, if you get a chance. That appears to be a very significant error. Perhaps sufficient to convert DRAW into LOSS.
The reason I selected this node was it was the first node where I thought the game strayed from “best play”. As in many games, one sides position slowly deteriorates due to inaccurate moves. In many cases the individual moves taken by themselves aren't enough to cause a loss. The cumulative effect of several inaccuracies is what causes the position to become lost. Sometimes it's very difficult to determine which move is the one that changes the “true” evaluation from a draw to a loss. E.g. After 21. … Bb4 22. Bc1 there are many replies possible. (eg. a6, a5, Bc3, Qd6, Qc7, Rf7, and Kh8 for example). I did a deep analysis on one of these variation (Rf7) and +1.72 was as high as the score got. The position was such that it still looked contested. So, maybe Bb4 isn't the losing move. It would take more time than I have. So I left it there. I try to avoid the whole issue by backing up till the first detectable inaccuracy if I can. So I did look at 21. … Bb4 in depth and yes the position is bad after that move.
In the mean time my computer developed problems. It was down for over a day. I diagnosed it as either a MB VRM problem OR a power supply problem. I ordered a new power supply which will be here tomorrow. In the mean time my machine is crippled. So, for at least a few days I won't be doing any deep analysis.
If that fixes the problem then I'll wait to build a new machine. If it doesn't fix the problem then I have several options.
1. Do nothing and SUFFER for the rest of my life.
2. Wait for high core count Cpu's and suffer in the mean time.
3. Build a Ryzen 5 3600 machine as an interim machine until high core CPU's are available
4. If 3. then build a high core machine and give my wife the Ryzen 5 3600 machine.
5. Build a Ryzen 9 3900Z
6. If 5. build a high core machine when available and give R9 3900X to wife.
7. Build a Ryzen 9 3900X and keep as my main machine.
My wife offered to take ANY interim system I build, including a Ryzen 3900X, as her new system. Then I would be free to build a 3950X or Threadripper system when they become available. I'm not sure how much use she'll get from the new system as she doesn't use her current desktop system and plans on buying a new laptop at the end of September in any case. It would be nice to have a 3900X system and a 3000 sieres Threadripper system in the house but I'm not sure it's worth the extra money. I don't really use her computer now and I don't see that changing much in the future. So, this option may sound good but in the end I think the interim system will be a waste.
I'm not much on suffering so option 1 and 2 don't sound too appealing. If I do option 7 I won't be very happy as it's not the machine I really want plus my wife keeps warning against this option.
So what do you think I should do if the power supply doesn't fix my problem?
