1.Na4 is strong indeed.

what about 1. Na4 ??

Solution of yesterday:

33. e5 Rf5!? Strange this move is not considered..

This day:

Perhaps: 1. Rb1 Nd5 2. Nxd5 Qxb1 3. Nxe7+ Kh8 4. Ng5 Be6 5. Qg4

Any ideas?

I like the Rb1 idea, too. Perhaps we need a preparing move to prevent this annoying 1...Nd5.

For example:

1.Kf2. What are the possibilities for Black? The queen can't move, there is no way to free it, so Black should create a counter-threat. Perhaps:

1... a4 2.Rb1 Qxb1 (I don't see an alternative) 3.Nxb1 axb4 and we should have a solid advantage.

Even after:
1...Bf5 we have 2. Ne1 and I think we win the queen for a rook and bishop.

I like R d 8 or R b1
