    Hello.

    I just played a blitz game with someone that had roughly the same rating as me, and although it was kind of poorly played the endgame interested me.
    I really wonder if the first (after black’s 22th move) and the second (after black’s 43th move) phases of the endgame were a win or a draw with best play, and what I should have done better.
    If you could give a look to the game, and perhaps give me some advices, I’ll appreciate. Thanks in advance.

    Hi Marc

    If you have gone over the game with Houdini I doubt if there is much
    we can add, don't these things have tablebases that kick in when there
    are so few bits left?

    Threads entitled "......Endgame" are always worth a look as I'm of the
    opinion that at our level 90% of the games should never have been an ending.

    What usualy happens is a player enters a lost ending and asks for help in saving it.
    Out come 110 suggestions on what endgame books/Vids/Sites are best
    whilst the real problem was in the middle game.

    There was an interesting moment here when the game could taken a
    more dramtic ccourse.

    I don't think you can win after the last rook trade. If he just holds his K on f3 and P on g4, where does your K break in? Not a4, because he has Ke2, assuming he can't just take some pawns with the Bishop.

    Hi greenpawn, yes endgame table bases (EGTB) can help in post game analysis, but not there. Five piece table bases (this includes the kings) use up 4Gb of hard drive. By the time you're up to 6 pieces that hits the terabyte mark. There is no way on earth that an (affordable) engine equipped with EGTB is going to cope with that position, they'll just moronically test the table-base at the end of their 20 move line and find most positions score the same. To the extent that some engines will come out with better moves if EGTB access is turned off...

    Cheers Deep Thought.

    I know these things are out there and they were limited to a certain
    number of pieces. Not sure how many though, last I heard it was 7.
    So it' seven counting ALL the men I thought it was 7 a side.

    So eventually they are going to solve Chess backwards.
    Give me a shout when they have a 32 piece TB. Be interested what the
    first White move will be.....be funny if they discover no matter what White
    plays he's losing...White's in Zugzwang!

    I read an artilce in NIC years ago when these things were making an
    appearance that a 'clever' computer in a position say KRPP v KR would
    just toss away it's extra pawn so it could then access it's TB and play
    the ending 100% accurately with zero time used.

    Just finished a nice unbeaten blitz session at Gameknot.
    Played approx 20 - won the lot.
    Tonight I'm hot and lucky - other nights I'm cold and Mr Blunderman.

    Of course it helps you see the Mouse Slip to end all Mouse Slips.

    38...Bc3 springs to mind,... looks strong

    In fact 38...g5 is even stronger - winning, according to Komodo (-1.61) - whereas 38...Bc3 only gives you an advantage of -1.05 or so (after a minute or so of running it)

    Hi Ptobler

    Honestly mate without a diagram or PGN moving thing you effort is wasted.
    The lads have to go back to original game, copy it, paste it into a PGN
    mover, then flick back to RHP and enter your line move by move to see
    what you are saying.

    That is too much to ask from the lads on here.
    Chess players are famously lazy. That is why many Chess players wanting
    to start a family marry pregnant women because they cannot be bothered
    making love and would rather have someone else do it for them.

    I'll do the cutting and pasting this time but it would have been easier if you
    had done it because you had line already to go up.

    Perhaps all you work and time will get a response.
    (if the line is sound then I want ½ the credit.)

    Personally I think the lad found his own answer when he said here:


    45...g5 was better than 45....f5 the plan with g6 and then f5 creating two
    connected passed pawns looks very good.

    Your line:
    (or your computers....'Komodo' what is that? another chess program or your pet name for Fritz?)
    Starts here.


    Black to play.
    (I would not class this an ending whilst both sides have two Rooks.)
