How fast you can play Stockfish?

[Jouni]

In CuteChess or similar interface. 10ms for move? 1ms? 100μs? I am just curious .

Not sure what you're asking about exactly, but in general can't go below 1ms per move (that's the UCI time resolution)

[dangi12012]

If you want high performance engine vs engine you have to directly link the respective DLLs into a management executable.
The path over stdio inclusive parsing the strings is way too slow.

Forget GUI- way to slow (because most GUIs are synchronous)

Only then you can even think about time controls below 1ms.
Does it make sense to play that fast?
Not really you can cap the number of nodes in UCI to achieve a minimum level of play. And have as many instances as you like if nodes per second are comparable.

[Jouni]

With fixed nodes You can play very fast in CuteChess GUI. From test game 500 nodes per move:

Code: Select all

48. Qg5+ {+12.44/3 0.001s} Kf3 {-6.81/7 0.001s} 49. Qf6+ {+11.84/4 0s}
Ke3 {-6.81/7 0s} 50. Qg5+ {+11.84/3 0s} Kf3 {-5.20/8 0s} 51. Kc2 {+8.77/3 0s}
Rh2+ {-4.00/6 0.001s} 52. Kb3 {+10.93/4 0s} d3 {-4.33/6 0s}
53. Kb4 {+10.37/3 0s} d2 {-3.07/7 0s} 54. Rc3+ {+9.49/4 0.001s}
Ke2 {-4.42/7 0.001s} 55. Qg4+ {+9.77/4 0s} Kf2 {-5.64/7 0s}
56. Qf4+ {+11.31/4 0.001s} Ke1 {-7.85/6 0.001s} 57. Qxe4+ {+10.60/4 0s}
Kd1 {-6.64/7 0s}

Some moves below 1ms .

If you are interested:
OliThink plays 4000 games in less than 2 minutes with time control 400/1 (One second for 400 moves, being 2.5ms for move) and there is no issue with time flagging. Using cutechess-cli.
Playing faster like 800/1 yields in too many draws, still there is no issue with time control.

Funny Fact: The faster the time control, the better OliThink performs against any other engine, even Stockfish. It's built for speed, not so much for chess knowledge.
