Phony Benoni: <Murky> I can never resist challenges like that. I count 32 repetitions at all, under current rules.Here's a little chart. The three squares are, in order, the positioin of WR/BR/BK:
b1/d6/b6: B49 B57 <B61 B67>
b1/d7/b6: B43 B47 <B55> W59 W61 <B69 B71>
b1/d7/c6: W47 W53 <W55> B59
b1/d8/b6: W43 W45 <W49 W51 W57 W63 W65
W67 W69 W71>
b1/d8/c6: B45 B51 <B53 B63 B65>
b2/d6/b6: W50 W58 <W61 W68>
b2/d7/b6: W44 W48 <W56> B58 <W70 W72>
b2/d8/b6: B42 B44 <B48 B50 B56 B62 B64
B66 B68 B70>
b2/d8/c6: W64 W66
b3/d7/b6: B60
b3/d7/c6: B46 B52 <B54> W60
b3/d8/c6: W46 W52 <W54>
The players could have made it all the way without repeating. There are 18 possible configurations of the three pieces (WR b1,b2,b3, BR d6,d7,d8, BK b6,c6), and they only used 12 of them. Each of the 18 positions could be repeated four times, twice with each color to move, making 72 possible positions. That's 36 moves on each side possible without a repetition, and they only made 30.
I think.
