    Haven't analysed it by computer, KB, but I think I would have tried the bold 16.Ne4 instead of 16.b3. The knight threatens to go to either f6 or g5, and if it's taken, the rook comes to the fourth rank. Then the only way to stop Rg4+ is with ...f5, and after the en passant capture White seems to be having some fun. Just a thought .

    Cheers,
    Kevin Casey

    Stockfish says the boring 16.b3 is best by some margin (+5). 16.Ne4 the main line seems to be the following:

    ... which white may be winning but it's harder.

    However, Stockfish prefers 17.Ne4 to my 17.Rac1; it is faster. This is also a nice solution: 17.Re3! Nf2 18.Ng5!

    Nice game Kevin. Just wondering why did you give 14...Na5 as ?? and what would the correct move be? If 14...f6 intending Rf7 do you take the draw with Qg6-h6?
    So what's your excuse? For running like the devil's chasing you?

    See you in another life, brotha.

    Stockfish evaluation goes from 0.00 to +5 for 14...Na5, but also on general principles because black is wasting time putting a potentially defending piece far from the action and failing to effectively address white's rook lift threat.

    It seems that there are five (!) black alternatives that draw, though maybe some of them would fall over on very deep analysis:

    14...f6, the simplest, when white has nothing better than the immediate perpetual, though if white is determined not to draw there is 15.Nxd5 which leads to a (fairly bad) position with three pawns for the piece.

    14...f5; this also allows the immediate perpetual but white doesn't have to force it right away and can try various things to see if black makes a mistake

    14...Re8 intending ...Bf8, or if white allows it ...Kg7 and ...Rh8; this leads to a nest of perpetuals

    14...Qe8 intending ...f5, ...Kf7 and ...Qd8; this also leads to a nest of perpetuals

    14...Be8 intending ...f6. White can draw by 15.Ne2 (alternatives may leave black better) 15...f6 16.Nf4 Qd7 17.Ng6 Bxg6 etc.

    A pleasant attack against a 2280-rated player on chess.com:
    K. Casey vs. Hapless Victim King's Indian Defense

    1. c4 g6
    2. d4 Bg7
    3. e4 d6
    4. Nc3 Nf6
    5. Bg5 c5
    6. d5 h6
    7. Bh4 Ng4
    8. Qd2 f5
    9. f3 Ne5
    10. f4 Nf7.
    11. Nf3 fxe4
    12. Nxe4 Bf5
    13. Bd3 Nd7
    14. 0-0 0-0
    15. Rae1 Re8
    16. Ng3 Bxd3
    17. Qxd3 Kh7
    18. b3 Bf6
    19. Nh5 Bxh4
    20. Nxh4 Nf8 With Black in ultra-grovelling mode, it's time to go in for the kill and devour those weak white squares.
    21. Re6! Nh8
    22. f5! Nxe6 Taking the knight at h5 also loses, after 23.f6+ (discovered check).
    23. fxg6+ Kg8
    24. dxe6 Rf8 There seems to be nothing better.
    25. Rf7! 1-0 Taking the rook (with either piece) leads to a grisly smashing. Meanwhile there's the threat of 26.Rg7 mate.

    Sorry, messed up formatting towards the end above. As penance, I added some computer-assisted lines.

    ^ Nice game CF.

    It's instructive that white cannot even exchange queens due to the back rank. 18.Qxd8 Rxd8, and even with the move, white cannot avoid disaster on the back rank. 19.f3 is the only move to avoid mate and then 19. ...Rd1+ picks up the bishop, when white's queenside woes continue with the pinned knight.
    So what's your excuse? For running like the devil's chasing you?

    See you in another life, brotha.

    ^ Nice game CF, could also have found a home in the miniatures thread. I guess black had only considered Nxh8+ (where white is winning the house anyway) and not Ne5+ covering the d7 square.
    So what's your excuse? For running like the devil's chasing you?

    Thanks for your generous comments, Desmond. I had forgotten about the miniatures thread.

    In post 568 I gave a win against chess.com "Super Grandmaster" Level 24 ("2900"). I aimed to also beat chess.com "Maximum" Level 25 ("3200") and it has taken me nearly a year and just a dozen or so draws from thousands of attempts, but finally:

    PGN Viewer
     

    A few days ago I noticed that in this particular line of the Spanish Four Knights it was susceptible to playing ...g5? when white is much better after the Nxg5 sac. Even so it took me something like 10 attempts in various games where it allowed this sac before I finally beat it.

    I am now trying to beat all the engine bots with black, mostly by playing the French against them of course. I beat all up to level 20 by 5 Nov, and level 21 on 10 Nov. Level 22 ("2600") put up good resistance for a long time and seemed very hard to beat with some very interesting games but then succumbed to this terrible blunder:

    I have just played 21...d5-d4. The correct response is 22.c4! I was quite surprised to be given the point on a platter by 22.Rd1?? dxc3.
