Nakamura's position still drawn but it looks like he will blunder and lose the 4th game, leading to 2.5-1.5 for Dragon.

It's 100% lost

When I posted it was drawn. :wink:

In this last game, Dragon succeeded in keeping the position complex and messy very long, and Hikaru's king in the center made it much harder for him to find the right moves.

Was it regular Dragon or the MCTS version playing tonight ?

When he missed Nd7 he basically lost.

I find it amusing that people are posting sf12 evals in the chat, given how much stronger Dragon is in odds play. :-)

It seems are simulated Nakamura results are reasonable. So we can match Stockfish 12 with sim Naka. And see how bad SF12 plays with a handicap.

It was regular Dragon. But I think we'll go with MCTS Dragon tomorrow, mainly for variety. MCTS Dragon does worse than normal Dragon giving handicaps to other engines (maybe not Lc0, that's worth testing), but it did better against my son and the regular Komodo MCTS did much better than regular Komodo giving handicaps to GM Alex Lenderman. Perhaps simulation won't predict well in this case.
Komodo rules!
