Time Management Regression: Search collapse to Depth 1 in ultra-fast time control (9s+0.1s)

[goni-K]

Describe the issue

Stockfish 18 exhibits a critical time management failure in ultra-fast increment scenarios. Under a specific time control (5% of 180+2 blitz = 9s+0.1s), the search algorithm intermittently collapses to Depth 1 for multiple consecutive plies, leading to catastrophic blunders against significantly lower-rated engines.

Environment:

CPU: Intel(R) Core(TM) i5-4570 @ 3.20GHz

RAM: 8GB

Version: Stockfish 18 x64 (AVX2-5Pct)

Case 1: SF18 vs Sirius 9.0 (2609 ELO)

The Anomaly: SF18 dropped to Depth 1 at move 36.

Proof of System Stability: On the same hardware, Sirius 9.0 maintained Depth 18.

Case 2: SF18 vs Dirty CatPaw (2026 ELO)

The Anomaly: SF18 flatlined at Depth 1 from move 58 to 80.

The Blunder: At move 77, SF18 played 77. Qb5 at Depth 1, hanging a Queen in a +3.4 won position.

Evaluation Gap: SF18 evaluated move 77 as -0.06/1, while the opponent (at Depth 16) correctly saw +15.49.

Conclusion:
This is a purely internal Time Management (TM) issue. When the engine's time bank is low, it fails to allocate even the minimum search window required for basic tactical awareness, while weaker engines manage the same 0.1s increment efficiently.

Expected behavior

I expected Stockfish 18 to maintain a stable search and tactical awareness, even under extreme time pressure (0.1s increment). Specifically:

Search Stability: The engine should never "flatline" at Depth 1 for multiple consecutive moves. I expected it to maintain a minimum safety depth (e.g., Depth 4-8) to avoid basic tactical blunders.

Resource Management: Since other engines (Sirius, Tcheran, Dirty CatPaw) consistently reach Depth 12-18 on the same hardware (i5-4570) and time control, Stockfish 18 should be able to utilize the 0.1s increment to perform a meaningful search instead of bypassing it.

Evaluation Integrity: The engine should not drop from a winning evaluation (+3.4) to a losing one in a single move due to a "panic" search. I expected the Time Management logic to prioritize move quality over lightning-fast execution when the increment is 0.1s.

Steps to reproduce

Use Stockfish 18 x64 (AVX2) on a mid-range CPU (e.g., Intel i5-4570).

Set up a match against engines rated between 2000-2700 ELO (e.g., Sirius 9.0, Tcheran 11.0, or Dirty CatPaw).

Use an extreme time control: 9 seconds base + 0.1s increment (simulating 5% of a standard 180+2 blitz game).

Run a tournament of at least 50-100 games.

Monitor the search logs (UCI output) during the transition from middlegame to endgame, especially when SF18 is playing with the White pieces.

Observe the frequency of "depth 1" outputs in the UCI log while the opponent maintains a stable depth (e.g., depth 14-18) on the same hardware.

I think we will need the UCI logs to confirm the issue, generally I would expect this to be an arena issue, since the 9+0.1 time control is essentially what we use for testing most of the time, and we do not observe this issue.

Hi Joost,

Please take this report as a technical observation. The issue is clearly visible in the real-time PGN files generated by Arena; you can cross-verify the time discrepancies by looking at the search depth of the opponents at those specific moments.

Just to be clear: I am simply a chess engine enthusiast who enjoys organizing championships and tests for my own hobby. My intention in reporting this is purely to provide information that might be useful for Stockfish’s development.

I am not a developer, I am not trying to point out 'flaws' for the sake of criticism, and I certainly do not have an 'engine of my own' to promote or sell. I just want to contribute to the community with what I observe in my tests.
Additionally, you can find my extensive testing of various Stockfish versions and other engines on my website: https://goni-k.github.io/RChessEHC/.

All the data from my championships and tests are documented there, which might provide further context on how different versions handle these specific time control conditions.
Respectfully,
goni-K!

I understand, just trying to gather more input to be able to reproduce the issue. For that we need to understand what options arena sends to stockfish specifically, as with the default options a tc of 9+0.1s is absolutely no problem for SF, we test that often and even more extreme versions (like 1+0.01s)

To enable writing a debug log file see
https://github.com/official-stockfish/Stockfish/wiki/UCI-&-Commands#debug-log-file

It should be possible to set that option in Arena and capture the full communication.

I've enabled both the Arena Log Process and the Stockfish Debug Log File option.

While Arena correctly saves the full tournament log in a single file, the Stockfish internal debug log overwrites itself every time a new game starts. Since Arena restarts the engine for each match, the STF log only preserves the last game played.

This makes it difficult to isolate the engine-side data for the specific game where the bug occurs. Is there a way to force Stockfish to append to its debug log instead of overwriting, so I can cross-reference it with the Arena log?

[robertnurnberg]

For now Stockfish's Log File from a single game will suffice. We just want to check the Arena transmits the correct time control data to the engine.

For now Stockfish's Log File from a single game will suffice. We just want to check the Arena transmits the correct time control data to the engine.

I think the following log snippet should be sufficient.
It clearly shows the go command being sent by Arena with the correct increment (winc 100 binc 100).
This confirms the GUI is transmitting the data correctly.
