Which could be 2 draws or 1 win. A 1700 player, if I had to guess, is at least 600 points worse, which would mean 1 win of every 64 games. Or two draws. Note that this is a rough estimate of 200 points meaning a 1-3 result, which is close but not exact. The last such challenge was in this time frame... ie long game I wouldn't venture to recall if it was 40/2ish or 30/1ish or something close) and we went over 50 games with no draws or losses. I don't see where any modern computer would be much weaker than mine, as with PIII/600's and 650's running, they are not a whole lot slower than a quad xeon, so I'd think this would hold up on normal hardware as well. Best bet is to simply test it, although 50+ games takes a while. The test we did was about 1-2 games per night, and we didn't play every night...
