Yes, my vote is for Ne6.

g6+ seriously risks drawing the game. g6+ Kh8/ Nxg7 Qxg7/ Ne6 Ne7/ Nxg7 Kxg7/ Qf4 Rfd8 and if we allow black to play Nc6-Ne5 + Bb4 + a5 we are going to have a tough time winning. We may need to sacrifice a rook for the bishop in b4. I do not like this a bit when we are steam rolling in the K side (the computer will go for something stupid rather than going for this fortress, but it is risky to trust that).

With Ne6, we could take in g7 w/o closing the position. If black plays fxg5 hxg5 hxg5 to avoid g6+ their king is wide open.

Ne6

also to avoid a possible fortress, as pointed out by Miguel. With Ne6, we could also get an option to play Nxf6 later on, where Black can't take back with the pawn due to mate. But this requires our g-pawn to be still on g5.

After analyzing the position more carefully, and having in mind what Miguel recommended, I change my vote to Ne6.

Best,

I will take the Forum move as:

31. Ne6

Thinking MDC needs about 7 days to think on this one..... :wink: regards

24 Hours of hard searching and MDC plays:

32. ... hxg5

[d]1r3rn1/pq4pk/3pNp2/2p2PpN/2PpP1QP/2bP4/8/3R1RK1 w - - 0 2

I really liked and hoped MDC would play 32. ... Kh8. But it threw out this move after about 10 minutes.

Best regards

hxg5

black has same problems as one move before, with the h column open :-)

Miguel
PS: black is forced to play fxg5. It may be able to resist a bit placing a Knight on f6. We should consider f6 avoiding that followed by, at some point, Kg2-->Rh1 (Qh3?)
Or Qh3 Nh6 f6?
