new tournament stash against stockfish fixed nodes

Post by Uri Blass »

opening position.
stash start with 1000000 nodes per move and stockfish with 10000 nodes per move
After every round of 2 games if it is a draw the nodes of stockfish is multiplied by 2 and the nodes of stash are multiplied by 4.
If one side wins then in the next round the loser nodes are multipled by 2.

First 2 round's result is 1-1




stockfish won match 3:

stockfish used 1024 hash when stash used only 16 hash but I do not believe hash change much at these fast time control.

In any case I am going to increase the hash size to 1024 in the next matches.
