    I guess I haven't posted in a while. I'm on kind of a semi-vacation from chess.

    Here is an interesting position that I came across.



    Before I give anything away, I'll just leave this up for a while.

    It is white to move right now.

    Well the first thought would be

    1. Rf8+ Kxf8 2. gxh7 Ra4+ 3 Kg5 and white Queens next move.

    Yes, that looks simple enough. I wonder what Black's last move was?

    Lasker actually played 1.Rf8+ Kxf8 2.gxh7, leading to the following position:



    Black to move

    I can't find a way to refute 3...Rh4! yet. It looks winning for black.

    You didn't fall into the trap (although my second diagram with black to move may have been a good hint ).

    After 2. ... Ra4+, it doesn't matter where the king goes !!!

    3. ... Rh4 4.Kxh4 g5+ !!

    Black's a pawn queens, and white's h pawn doesn't !!!

    This is from the simul Lasker-Loman 1913.

    Even the great ones can fall into a nice deep trap.

    Let me change that a bit.

    This position is "adapted" from the simul Lasker-Loman.

    According to chessgames.com, the actual game was played in 1903 and had more pawns on the board.

    The "adapted" position is from an old issue of Chess Life Magazine.

    I suppose if Kramnik can get mated in one by Fritz, then anything is possible, although this case is far more understandable, since it was a simul.

    I wondered why the position looked more like a chess problem.

    They took a few pawns off the board.

    Funny that you give the exactly correct losing line. There are some twins of this idea too - but this is the most well-known version I believe.

    This position is drawn. There are no tricks (Rf8+??), and after a bunch of pawn trades we will reach a drawn position (KR vs. KR, or KP vs. K w/o opposition).

    I should have known there was more to this position than the obvious Rf8+, which any experienced player would have seen in 0.5 seconds.

    The game that the position is based on, plus a few other examples, can be found here:
