# Thread: Combinations We Should Have Known About-The More Obscure The Better!

1. ## Attempting some un-machine aided analysis

Ok, Michael. Some un-PC software assisted analysis.
(a)Try 1 Na5 Qxh1+ 2 Kd2 Qd5! and Black wins. (Na5 can only work if b7 is undefended. So point taken)

(b) Try 1 Nd6 Qxh1+ 2 Kd2 Qd5 3 N (say d) x f7+ Bxf7 4 Nxf7+ Kc8 and I think the best white has is a draw by perpetual check. If 5 Rc1 than one of the N's goes to c6 and Black wins.

(c) Try 1 Rc1 Qxh1+ 2 Kd2 Qd5 and again no killer.

So for now I am stumped. Looks like a different first move, or I am missing something in the Nd6 line. Need to look at it in daytime....(This is why Baron is an FM and Adamski is a patzer.)

The puzzle is reminiscent of one of Paul Morphy's games (maybe v Duke of Brunswick) where he sac'ed 2 R's. James P. was Morphy white here?

2. Sorry for the Nd6 answer, I should have said Nb6 as this leads to a quickish win if black decides to be a ravenous glutton and pick off the two rooks.

1.nb6 qxh1+ 2.kd2 qxa1 3.nxf7+ bxf7 4.bc7+ kxc7 5. qe5+ kxb6 6.qc5+ ka5 7.b4# And its all good in da hood !!

3. Its Cohn vs Chiszar 1944 which oddly I can't find in any sources other than How to Become A Deadly Chess Tactician

4. White plays Na4 and offers a draw. What combination is available to black?

This is a famous position that occured between not so famous players in Spain in the 1930's.

There's quite a lot of discussion of the history of it on Tim Krabbe's site. Caruana won a vaguely similar position not long ago.
