trying to compile ROC with VS2017 only fails due to an error in line 58:

Re: New engine "Roc"
That line is a template forwarding function. Can you find the line of the template instantiation? You can reach me directly at teamhyer at yahoo dot com.

Re: New engine "Roc"
think it is line 46:
template<class F_, typename... Args_> int TBProbe(F_ func, bool me, const Args_&&... args)
with the error "too few arguments to call" in line 58:
(me == White), std::forward<Args_>(args)...);
template<class F_, typename... Args_> int TBProbe(F_ func, bool me, const Args_&&... args)

Re: New engine "Roc"
The non-HNI* binary of Roc 0.9 crashes instantly when I try to install it as a UCI engine in Arena 3.5.1 build 2861 under Windows 7 Home Premium x64.
* I have to use non-HNI builds because my Intel Core i7-2600QM is a Sandy Bridge and supports POPCNT but not BMI2.
The 0.9 binary can install itself as a Winboard engine, but then it still won't analyse (does nothing when started).
When I install the binary in Babaschess 4.0 build 12274, either as a UCI or Winboard engine, and attempt to analyse the starting position with it, it opens 8 empty Windows Terminal windows (with Roc_0_9_x64.exe in the title) and does nothing else.
I haven't yet tried to compile a binary from the 0.9 source. I'm using the non-HNI binary of Roc 0.8 for now, which works correctly with Arena.
Anyway, what I wanted to address is Roc's time management - Roc 0.8 seems to play too fast, in particular, to play a move from the PV instantly without recalculation if the opponent plays a move from the PV calculated by Roc on the previous move.
This can sometimes backfire, as in the below example, where, at move 28, having 1:34 on the clock vs Fizbo's 1:16 (the time control was 3 min + 3 sec inc.), Roc searched to base depth 15 only. It played the correct 28... hxg5, but the problem was that its PV included 28... hxg5 29. Qxg5 b5?? because of the horizon effect (it was expecting White to play 30. cxb6, thinking that 30. Rd3 would lead to an equal position). After Fizbo 1.9 predictably recaptured on g5, Roc played the 29... b5?? from the PV of the previous move.

I don't know the effect of this time management on the rating, though - it indeed may be beneficial if, in most games, Roc manages to maintain a bearable position until the opponent gets into time trouble and blunders.
* I have to use non-HNI builds because my Intel Core i7-2600QM is a Sandy Bridge and supports POPCNT but not BMI2.
The 0.9 binary can install itself as a Winboard engine, but then it still won't analyse (does nothing when started).
When I install the binary in Babaschess 4.0 build 12274, either as a UCI or Winboard engine, and attempt to analyse the starting position with it, it opens 8 empty Windows Terminal windows (with Roc_0_9_x64.exe in the title) and does nothing else.
