Hamsters made a mistake here,within 2-3 seconds it played:35...Rb8b3, in a 5+0 game...when given more time,it actually sees Rb2b3 but that is the slightly losing move too... atleast when given enough time this game could actually end in a draw.

Also I don't understand the 27...a5 pawn move..a5 would only be useful in the later stage of the game because the position was turning out to be critical.

Hamsters sure is an interesting opponent,it doesn't play dull game unlike some of the engines out there that values material/plays dull and difficult positional chess,Hamsters is good at open position type, whats more is that it is interesting,what with its launch of pieces on queen side....
but it does need some improvement on king safety, pawn structure(main weakness) and general understanding in positional chess, it does have some understanding though when given enough time. Hamsters's pros are:that it is good at combinations, and openings,it does understand plans of the opponent in the earlier stages of the game especially when it plays without book and would eventually outwit you with surprise moves,it did find ways to break-open the stonewall, somewhat typical of other 2600+ engines strength engines when it comes to tactics and endings.I did not play this in an anti computer 8 pawns way.

Hi Swami,
thanks for the chess lesson but you made a big mistake, I have now taken note of everything and will stuff all of this in Hamsters 0.7 and THEN you will be 0wn3d nyaahahahha!

Well if I can, actually. After Graham hinted at weak pawn play I did try to tune the pawn evaluation parameters a bit up (which makes them comparable with other engines I think) but without success. Also king safety in Hamsters is peculiar to say the least, but so far I couldn't improve that either. Will definitely try harder though.

P.S. It seems Hamsters is irresistibly attracted by R8b3... even at 1000 KNPS it takes it two minutes to change and switch to R2b3... ahhhh, so little time so many things to fix!

Oh...I think one game won't tell you a lot about my playing style
Actually Hamsters engine would defeat me at longer time controls,with tournament type settings, this is one lucky win from me, other games,I make weak move at some point of time that Hamsters take advantage of...
If I play the openings I know very well, then Hamsters would have difficult time in blitz (that includes Sicilian dragon,Najdorf,Caro Kann, French and English) but will defeat me anyway but not so easily

Also king safety in Hamsters is peculiar to say the least, but so far I couldn't improve that either. Will definitely try harder though.

It is extremely good with major pieces, and it thinks like other strong engines in remaining other moves except a5,Rb8b3,Qc7...
If you get time to fix these stuff, then Hamsters will surely cross 2800 no doubt

P.S. It seems Hamsters is irresistibly attracted by R8b3... even at 1000 KNPS it takes it two minutes to change and switch to R2b3... ahhhh, so little time so many things to fix!

Well,other engines avoid Rb8b3 in a short time...and they all see Rb2b3 there...

I think I will play 4 more games against Hamsters again sooner,will keep you posted(cherry picked winning games from my side wonly! else those who dont get along with me well(few I think) will start boasting about their chess )...by posting their games against Hamsters...I dont wanna hurt the Hamsters this way by letting them do that...

hxg5? What for? b5,Na5 or Na7 etc quick launch for an attack on opponents king without hesitation

g5? Should never open up the king's pawn in the middle of the game where your opponents king is castled in the queen side,the opposite end and that it allows your opponent to attack your king side pieces effectively and results in material disadvantage or king check mate threat in later stage of the game...

suggestion b5.

Nfd4? Other engines suggest a5,Qe7,even Ncd4

e5?key Mistake, Nf5 would have been better.

Analysis by Hamsters 0.6:

1. ± (1.19): 24...e6-e5 25.h2-h4 Bd7-f5 26.Ne2xd4 Nc6xd4 27.Bd3-c4+ Kg8-g7 28.h4xg5 f6xg5 29.Qf2-g3 Rh7xh1 30.Qg3xe5+ Kg7-g6 31.Rd1xh1 Ra8-b8 32.Qe5-g3 Bf5xe4 33.f3xe4

(, 05.01.2008)

Hamsters at Depth 13 still prefers e5 which was dismissed by other engines in an instant.

Anyway,I think Hamsters played overall interesting game ...

[Alessandro Scotti]

Hi Swami,
thanks a lot for this game! There is a suspicious piece of code that I added I think in Hamsters 0.2 or 0.3 and that doesn't look right. Without it things get somewhat better, even if some of the blunders you point out would be played anyway. I'll try to remove that code snippet and see what happens. If successful, evaluation of king safety will probably improve...
Also there is a pawn storm theme in this game and Hamsters doesn't know about that. I'll try to add that too.

Sure,Alessandro.I'm not in hurry, enjoy your vacation

Here is new Hamsters logo,The Hamster in gym, telling you how strong it is


Would be interested in knowing what Romi's(or Mike's/Tony's) reaction would be!

I was the first Hamsters fan!

I noticed it's interesting piece play from the very start. I just hope that Alessandro can continue to make Hamsters stronger with out sacrificing the playing style! That will not be an easy thing to do. And I know, because, Romi looses a lot of strength to, 'have an interesting playing style'.

Oh allright, I was talking about the logo, what Romi's reaction would be seeing Hamsters weightlifting

Romi would do the jigg, because, she would try to make it harder for Hamsters to drop that weight on her toe!

It is a very nice logo!

Apologies for being slow but which version should I download from: http://www.ascotti.org/programming/chess/hamsters.htm

There seem to be two SMP versions? Which is the right one?

Can someone remind me what SMP stands for? (Something Multi-processor I assume)
