I spotted pretty quickly that white's LSB and Re1 both converge on Pe6, which is supported only by Pf7, which in turn is supported only by black's king. Furthermore, my Ne5 is blocking my rook and attacking that Pf7. Naturally, the move that jumps out is <18.Nxf7>, undermining the now doubly attacked Pe6.

Starting with the (unclear) assumption that black takes the knight via <18...Kxf7>, we are now in position to take Pe6. But with which piece? My first inclination (based just on experience) that its often stronger to take with the piece that doesn't give check (the rook in this case). This opens the door for further tactics like discovered check (e.g. windmill) or double check. So, trying <19.Rxe6>:

And this does indeed produce some juicy threats: - If the K remains on f7 and the N remains on f6, then Rxf6++ (double-check) wins back the piece to go with the 2 pawns, with further attack to come. - If the 19...Kf8 (unpinning), then the Nf6 loses a defender, thus Bxf6 wins. So black needs to consider knight moves:
- If <19...Ne5> blocking my LSB,

This took a moment, but white can undermine the N with <20.Rxc6! Rxc6 21.Bxe5+> winning back both the N and R (plus another pawn). - If <19...Nd7> then Re7+ and Rxd7 next. - If <19...Ne8> then 20.Re5+ Kf8 21.Be7# - If <19...Ng8> This is another "thinker", but the forcing moves aren't too hard to find: <20.Re7+ Kf8 21.Rf7+ Ke8>

I was stuck here for a moment until I remembered that I had another rook! <22.Re1+!> with just some futile blocks until mate. - If <19...Nh5> then 20.g4 and the N has nowhere to go. - If <19...Ng4> (stupid) then 20.hxg4. - If <19...Nd4> (also stupid) 20.Rxe4+. Now, if black doesn't take the N, I don't think he actually avoids trouble because I still have Rxe6!. Guarding e6 (18...Re8) is pointless since it's double attacked. I think I should be happy. |
