I watched the extended highlights of each session, and the course looked fantastic! While the PGA Tour insists on benign setups that lend themselves to lots of birdies, the USGA and Seminole had no problem embarrassing some of the best players in the world.
I do wonder if they went too far in a few instances. The combination of the wind, hole locations, and firm and fast conditions meant that the players sometimes had no bailout, and no margin for error, and no chance for recovery. In a few of the sessions, you had to hit a near-perfect shot on 17, and if you missed your spot by 2 yards on either side, you'd probably have a near-impossible pitch/bunker shot.
As viewers and competitors, presumably, we want to see the course setup distinguish between good and marginal shots, good and marginal strategy, etc., which is why I personally tend to prefer a USGA setup over a PGA Tour setup. But if we go too far, such that even the good shots and good strategy are punished and the outcome is arbitrary, that's not enjoyable for anyone. I'm not saying this applied to the entire event, but I did worry that there were a few instances that crossed that line this weekend.
I'm generally someone who is happy to see the elite players challenged. While others complained about Round 3 at Shinnecock during the 2018 U.S. Open, I thought it was a blast to watch. So even acknowledging that I have a sadistic side when it comes to high-level golf events, I felt bad for the players in the Walker Cup and thought it went just a little too far over the line.
The one saving grace was that it was match play and the worst one could do was lose a hole. If this had been a medal play event, I think the reactions would be much more negative.
For the record, I would absolutely love to play Seminole in those conditions. I'd just prefer that I not have to keep score and that none of it be on television!
