mating against part of the set

I used single core and 4096 mbytes so I guess the analysis is reproducable.

Forward- Backward after 1.a3 took a little longer with 20 threads of 16x3.5GHz CPU than after 1.e4 and maybe both lines can be made shorter for the one or the other one move, but at least the difference will not be as big as one could suppose.

With only 8G hash I then just tried MultiPV=3 (more would have taken some longer to get reliable DTM again) with already full hash, in depth 44:

Having more free hardware now, I gave 1.a3 another one Forward- Backward with ShashChess this time, out of 30 threads of the 16x3.5GHz CPU, 12 were used with option Full depth threads and 32G hash:

I will be surprised if 1.a3 is the fastest mate and if it is mate in 15 moves then I guess 1.e4 should mate faster.

I analyzed a different position with 1 core(used 1 core to make the result reproducabl).

my favourite slowchess see mate score also against queen and 2 bishops

Let's stick to one position at a time, if you're really interested in shortest DTM, single core isn't the way to go in SMP- times with engines that support that well (so not to talk about Chest or Gustav), output gets reproducible as for certain hardware- software- time, but it simply costs much too much time to solution, even with Forward- Backward, which I would recommend at all not to have unnecessarily much hardware- time anyhow. Huntsman is gold standard besides the specialised programs Chest and Gustav, both of the latter ones take at short trials of mine too long for a position like the one of the first posting, much too much expansion of the tree at the very first moves. SlowChess has a good mate search of its own too, you'll get a mate score often much sooner than with engines without such specialised mate search, e.g. with SF dev., yet to get shortest DTM (not only any DTM in output) you'd better have Forward- Backward with this one engine SMP too and better then go backward SlowChess' lines with Huntsman, Chest or Gustav also to see, if there can't now and then the one or the other one move spared as for shortest DTM.
Anyhow, if you get a shorter DTM but 15 moves with best play of both sides, please show the corresponding line (still talking about the position the thread was started with only), if you see a blunder from Black's side in output- lines after 1.a3 with DTM 15 (second posting of mine), please show it as well.

I didn't say 1.a3 is the shortest mate for sure, could well be with enough hardware- software- time one could find a shorter DTM after 1.e4, 1.Nc3 or 1.d4 (at least these 3 first moves seem to also have about the same DTM to me) anyhow if you look at the output- lines I gave so far you'll see, there won't be so much difference between best, second and third best move as for provable DTM to call 1.a3 a "stupid move"

Best move with 15 moves DTM would mean best out of at least 3 equally "good" ones, I had already shown DTM 15 with 1.e4 and with 1.Nc3 too.

I do not have a proof that a3 does not lead to the fastest mate but this move does not activate a piece so I will be surprised if there is no faster mate.
