I can beat you all on this condition

Are you sure you can win every game? Black made a blunder by moving a6. :/

20. Nxe5 What else?

Dear <Ajian>, 

according to Houdini here, your twentieth move was inferior by a factor of ten centipawns to its best choice, which was 20. Qb1. It currently evaluates the position at -0.01 - full equality, but with a psychologically telling MINUS mark for the first time in this game... Again, Lasker would have liked the psychological ploy involved in getting you used to plus evaluations, only to hit you eventually with a minus...

Houdini, on its part, never asks "what else"... it always examined everything - including ideas of ...Rd4 and ...Rd8. 

Ultimately, it has, predictably perhaps, decided upon the simple recapture, 20...Qxe5. Its slight "psychological" moment of dipping you, if ever so slightly, into the minus regions has passed, it would seem, after it has soberly evaluated its response at its customary 17-ply depth.

After this no doubt exhaustive scrutiny it has again lost some of its courage in evaluation, and rather sheepishly, decided to yet award you with a plus eval of +0.14. 

- - - - - - - - - - - 

Houdini seemed rather agitated after it delivered its last move to me. I sat down and had a good talk with it. "What's going on under the Houd"? I asked. Its response was nothing short of astonishing. 

To cut a long story short, Houdini told me that it was deeply impressed by your play up to this point. "No human playing me", said the machine, "in one of these complex, open games with all of the pieces still on the board, had ever survived thus far with a plus evaluation! I'm seriously considering my future as a chess program!"

Houdini was literally sweating. 

As I wiped its fevered brow and tried to calm down its obvious excited frustration, I took the liberty (seeing its condition, and out of purely human care and concern) to offer Houdini a draw in your name.

It heaved a huge sigh of relief and promptly accepted without further discussion. It will certainly take for it some time to recover from the deeply disturbing experience of this game, let me assure you. I really don't know if it would ever come back to chess - it was asking me, sinisterly, about golf clubs and courses... maybe we will both find ourselves a new hobby.

It was clear, in other words, that your incisive play has burned through too many of Houdini's nodes. It is still licking its wounds as we speak. 

However, be this as it may, I could see that a possibility exists where you would not agree to this draw, that I have contracted in your name, and wish to battle on, unmoved by the obvious emotional impact you are creating on the poor electronic beast.

Should this be the case, please let me gently remind you that as this is move twenty, our partnership in playing this game out has reached its end, untimely or otherwise.

In this case, all that is left to me is to provide you with my best and warmest wishes for success in conquering anybody who would dare to stand in your road to glory from move 21 and onwards... be it machine, man or any other creature, whether factual or legendary.  

And with these words, I bid you goodbye, and remain forever -  

your humble servant, 

Solskytz

I'll continue with Stockfish 5, who disagrees with your Houdini in general, maybe because of the shallow depth (17 ply). Stockfish says it's going to have Ajian for dinner tonight. (A bit of trash talk to spice things up) 

<Ajian> can also download and use Stockfish 5, which is a free, open-source engine... then you'll be stuck with this game for 50 more moves and you'll get pretty much the feeling that I got...

Oh! I listened to your piano concert. I must say I was both impressed and surprised. Is there more from you on youtube?

Not just more, but thousands of classical pieces. I just set a playlist, and he plays hours and hours in the background. 

Solskytz, thanks for the delightful reads. You're great!

If Houdini is seriously considering its future as a chess program, I reset my case.

Use an engine and from this position on and play. :)

<Aetheldred> sure is :-) 162 videos and counting. Go to www.youtube.com/user/solskytz - then "browse" or whatever the right button is called nowadays (they keep changing it arounds to confuse the enemy). There's a bunch of it - and do feel free to leave comment. I love being in touch with my audience :-)

<MSC157> This is wonderful!! I had no idea :-)

<Benzodiazepine> Thanks :-) And I loved your final pun - of course in this context "reset" is much more appropriate than "rest". 

Of course I tried this with Houdini... I still believe it needs a few good days of rest before I speak to it about chess again... :-)

Thank you guys! 

21. Rac1. No more hanging on to pawns

can somebody move for black?

Stockfish 5 thinks there is only one reasonable move. At a depth of 33 ply, Stockfish evaluates the position at -0.63 for the only good move 21...Rd4. Any other move would give White an advantage of at least a pawn.

You're dead here ajian, and you know it.
