Houdini 4, Stockfish 14113021, Orka 141130 - Extreme Super Blitz - 5S + 50ms

This is a continuation of the time control test to determine which is the best chess engine for a specific time control segment and also to see if Arena 3.5 GUI can handle it. The time control chosen this time is 5 seconds base + 50 milliseconds increment which is faster than the Stockfish Fishtest short time control of 15 seconds + 50 milliseconds. Only Houdini 4, Stockfish 14113021 and Orka 141130 were involved this time to have shorter time requirement for the longer 500 games round robin.

The results showed that Orka won with difficulty against Houdini  with 15 points advantage and easily against Stockfish with 82 points gain. It is a mirror of the previous Super Blitz 10S+100ms match result.

In the match between Houdini and Orka, there were 4 losses by time forfeit where Orka lost all of them in successive rounds without making the first move. Something choked Orka which maybe caused by the "Chokehold" effect raging in the U.S. as of this writing.

Between Stockfish and Orka, there was one game lost by time forfeit committed by Stockfish in 55 moves.

Arena 3.5 is not popular in fast blitz matches compared to Cutechess and Blitzer but in this test with small percentage of losses by time forfeit, it may be useful. In my case, I discovered its usefulness when quickly finding the best Orka or Shark compile at the shortest possible time while still have the chance to watch the games coherently in fast motion.

Here are the results:

  1. John, at this insane levels, i can suggest using nothing but cutechess :-) All known GUIs distort results below bullet level.

    1. You are right. This was the truth that was buried in my consciousness since the time I experimented on all chess engine GUI's including non GUI cutechess. But just recently after I started this Shark thing, I began experimenting with faster time controls at sub 1 second per move with Arena GUI and found out that this "truth" is no longer true. With the right software and hardware, Arena GUI can handle 1 second base + 10 milliseconds increment way beyond the 15 seconds + 50 milliseconds used by the Stockfish Team.

      I was stunned yesterday when my pet Orka was demolished mercilessly by Houdini in 1 second + 10 milliseconds supremely insane time control using the Arena GUI without a single game lost by time forfeit. You will see this in a follow-up post. Two things I learned: Houdini is the Blitz King in this insane time control and Arena 3.5 GUI can be used with such time control with the added benefit that all the action can be viewed real time on the screen which is impossible with cutechess.

  2. Ok. Anyway watching your eyes looking at the screen may be more fun than watching the game. Besides, you wink your eyes and miss some moves. Eyes wide open then :-)
