How many tries ending in a stalemate can
you manage in a correct #2? With rex solus,
I got 93 in a minute, but surely this is no record.

I've also done rex solus, based on my 105 forced statemates here: http://matplus.net/start.php?px=1617122194&app=forum&act=posts&fid=prom&tid=2332
#2
 (= 16+1 )
100 tries!

Popeye counts 100 moves, so we have 99 tries and 1 solution.
Here are 100 tries:
 (= 16+1 )
1.Rc5!
P.S.: Pe7 can be removed, loses 4 moves, but wins 4 new moves. But there is no field to put the pawn with additional moves.

But here we have one mistake. of 99 ,,tries" in fact many are not real tries- namely initial position is already stalemate for Black! Thereby, which is their role if White only repeated it without intend to threat mate?
As real record for stalemate tries I ment it is clear only when: 1) White have many tries with one or more threats but every try also make stalemate, or 2)variant(s) with provided mate(s) from set play is/are unabled beacause stalemated tries.
At 2016 I found next original setting- mate in 2
White- Kh8 Qa5 Re3 Rg5 Bc1 Bd5 Sf6 Sf8 pd4f2h2h5
Black- Kh6 ph7
set-1...Kxg5!
Tries with stalemate-
1.Re-? (-2.Rg-/Sg4/Sg8#)
14 tries
1.Rg-?(-2.Re-/Sg4/Sg8#)
8 tries
1.Se4/S6h7?(-2.Qa6/Qb6#)
1.Se6/S8h7(-2.Sg8/Sg4#)
4 tries
1.Bd-?(-2.Sg8/Sg4#) 13 tries
1.f4/h4?(-2.Sg8/Sg4#) 2 tries.
In total 41 REAL STALEMATED TRIES as reason why White cannot to give mate !!
Sol-1.Sg6!(-) Kxg5, hxg6 2.Rf3, Rxg6#
Now we have challenge- is possible better(over 41 tries)?

In Franks setting I see only 19 real tries, when White have mating threat (14 with Pspromotions, Sa6,sa5,sd6,Qb6,Ba6).
Other ,,tries" are non-tries- what White get if 1.Ra1 or Ra2 or h8S??

Here the position, I hope, it's correct:
 (= 12+2 )
#2

@Dragan: Your objections are surely valid from some
*artistical* standpoint, but I asked for a mere
construction record.

And thus I go for 102 :-)
 (= 16+1 )
