Wow I found it?! I did a random move with a 25 second think and it was correct!?

@pask : I agree that the diagram position is completely won for black. But he has to combine the ideas of taking on d3 and making a discovered attack with his rook.

In the game, my opponent missed this winning idea (he played Nh4?!), and I went on to draw later. Humans do make mistakes

The knight move jumps (ha!) out at you at most forcing.  It leads to taking the rook on d8 AND trapping the bishop.  So you get control of the d file and a trap the bishop.  The king has no safe squares, so then I looked for mate.

Your training game is more complicated, but did you really draw?  If so, your opponent was awful, Nxf1 seems best.  Then it becomes more difficult to find follow up moves.  I played it against the computer, taking back moves until I found my way.  Very good exercise, but no way should white draw. 2. Rxf1 Bxd3 3.Qxf6 Qxf6  4.Nxd3 Nh4, and black is up a Q for a R with a much better position and should win some pawns and the game in time.

nice puzzle

Nice puzzle. I thought it was pretty evident from the cramped position that a Checkmate was close, but the rooks on the same file worried me. Once I saw the knight check and discovered rook attack, it was clear that was the best move, and that moving the pawn up to further restrict space was the right thing to do.

so did I

1...Nxf1 2.Rxf1, Bxd3 3.Nxd3, Rxf2 4.Qxg5, Rxf1+ 5.Kh2, hxg5

Nice problem!

Yay! I actually found it WITHOUT using a "Brute Force" search! Nice puzzle...esp because Gligoric is one of my "old-time" favorite GMs

I got it by eventually determining that there was probably a mate involved on the e-file vs White's immobilized King. My first approach to puzzles is: is there a possible/plausible mate? If no, then there must be a win of material.

lol so did I first try

Well done Ed ! That wasn't an easy one to find

Thanks for posting and I found the solution
