during testing of DS11 at 40/20 quad, i have noted on 3 of the games i have watched,which is approx 10% of games played,stange behaviour of ds11 what happens is k/ns suddenly drop to zero,now i know this happens with ryka also and has been discussed on this site but nothing like what DS11 does. i was wathing ds11-hiarcs and both clocks had approx 17 mins on them ds11 and hiarcs agreed +2.25 roughly suddenly on what appeared to be a straight forward recapture ds11 goes into deep thought 10 mins in itself that is ok hiarcs now replys in seconds, now ds11 goes into deep thought again for 5 mins leaving itself with 2 mins to complete 30+ moves which it plays at 4000+ kn/s. the result was a draw.wierd.
