26burtabel [4d\]: this is the game position
27burtabel [4d\]: you have control
28gunnar [4k?\]: When does it crash?
29burtabel [4d\]: in this position
30burtabel [4d\]: the rest is semeai reading
31burtabel [4d\]: entered by me
32gunnar [4k?\]: Ok.
33burtabel [4d\]: which was not one of the 3 in the triple ko...
34gunnar [4k?\]: It looked suspiciously much like a monte-carlo simluation...
35burtabel [4d\]: i think increasing MAX_STRINGS for this kind of stuff would be...
36burtabel [4d\]: embarrassing
37gunnar [4k?\]: Indeed.
38gunnar [4k?\]: In that case I'd rather rewrite the board code without string numbers.
39burtabel [4d\]: i will make a ticket
40gunnar [4k?\]: Please do.
41burtabel [4d\]: but i will fault the semeai code not the board code :)
