hallo MikeB :-)
thats awesome, im very curious about this analysis !
yes, after ....Ng5,Nxa3 i also thought Bf2 would be the move but i couldnt find anything after ...Nb5 eg
in my completely patzers eyes it looks like a draw because i have the feeling that black lost one tempo (which was important in the original...h6,Txh6 line i already was able to refute) with ...h6 (now Nxa3 !?)...im curious if McCain can find sth else than 0.00

Up to 1.2 trillion nodes , all 3 moves show draw score - zero after 15 hours of think - will let it run until I get home ...

after 1.8 trillion nodes searched - all draw scores for the best 3 moves, all over moves lose

Thank you very much for this deep analysis MikeB !
its unbelievable that even ...h5 is evaluated as a draw now but after some try and error i couldnt refute ...h5 (looks like sucide but seems to hold)
so the latest news are: 8.Ng5?! is probably only a draw after 8...Nxa3 !?
im already curious about our superbrains here trying to show that 8.Ng5 is still a clear win...the position is amazing, yes, but so far it looks like we have to adjust the main-line after the queensac, isnt it ?
Thanks again MikeB for your very deep McCain-run :-)
