Hi all,
This little double RR test at 1+2 saw without surprise the victory of Houdini. Behind, there were a lot of new engines (for me !).
A good surprise are Hannibal 1.4b and also Hakkapeliitta who fought like brave "Mousquetaires" .
Hakkapelitaa crushes Houdini 4 in 24 moves, see game N°100 in thePGN !
Hussar 0.4 is suffering for many time losses but is playing interesting games !
The cross table and the pgn zipped are available :

Have a nice day !

Re: ACCC_2014_Alphabetical_Tournament_Letter H.
Hello Arnaud:
In CCRL 40/4 complete list (date: August 2, 2014), I find Hakkapeliitta 1.0 x64 with a rating of 2517 ± 19; OTOH, Houdini 4 has a rating of 3233 ± 13.5 (more less). This is an Elo difference of circa 716 ± 23.3 with 95% confidence! It means that Houdini 4 should win more than 98% of the points against Hakkapeliitta 1.0... Hakkapeliitta won the lottery this time.

The opening is the poisoned pawn variation of the Sicilian-Najdorf.
Here are some analysis of Houdini (the evals are from the side to move, not from white's POV):
[d]r5rk/2qbbppp/p2ppn2/1p3PQ1/3BP3/2N4R/P1P1B1PP/1R4K1 b - - 1 20
First, it has some problems with 20.- ..., Rae8 (it was evaluated as +0.00 at depth 16/60).
Then, hash cleared and 20.- ..., Rae8 played:
[d]4r1rk/2qbbppp/p2ppn2/1p3PQ1/3BP3/2N4R/P1P1B1PP/1R4K1 w - - 2 21
At depth 14/51, Houdini started to think in 21.- Rb3 in the 16th move out of 57 possible moves! Then it came with depth 14/53 and a winning score.
Hash cleared again, and here is the analysis for the next move:
[d]4r1rk/2qbbppp/p2ppn2/1p3PQ1/3BP3/1RN4R/P1P1B1PP/6K1 b - - 3 21
Houdini thinks that black has the edge as long as depth 12/49.
The final position (this time with Multi-PV = 1 instead of Multi-PV = 3):
[d]4rbrk/3b1ppp/p2p1n2/1p1p1PQ1/3BP3/1R5R/P1P1B1PP/6K1 b - - 1 24
------------------------
Using Stockfish TCEC6 w32 PA_GTB this time:
[d]4r1rk/2qbbppp/p2ppn2/1p3PQ1/3BP3/2N4R/P1P1B1PP/1R4K1 w - - 2 21
SF does not want to play 20.- ..., Rae8 but once it is played (and hash is cleared between analysis), it has some difficulties until it gives a losing score to this move.
Final position analysis by SF:

Re: ACCC_2014_Alphabetical_Tournament_Letter H.
Hello Jesus,
First of all, thank you for the comments regarding the tournaments
Many thanks for your analysis : I knew that a gain against Houdini is a precious point !
It is obvious for an human player that the Blacks are completly wrong, playing here in the queenside, while the White prepares a good attack. Houdini (or else) is blind in this situation, and above all in a 1+2 game !
The move Nd5 is pretty nice !
Here is an analysis made by SF 5 (30 s/move) (sorry, in french for the pieces, and I "badly" translated the comments) :
(1) Hakkapeliitta 1.0 x64 SSE 4.2 (2200) - Houdini 4 Pro (2200) [B97]
B97: Défense sicilienne (variante Najdorf avec 7...Db6)
1.e4 c5 2.Cf3 d6 3.d4 cxd4 4.Cxd4 Cf6 5.Cc3 a6 6.Fg5 e6 7.f4 Db6 8.Dd2 Dxb2 9.Tb1 Da3 10.f5 Cc6 Last opening book move

16...Fd7 [16...b5 17.Tg3 Rh8 18.Rh1-+ ]
17.Tg3 Rh8 [17...exf5?? 18.Fd4 g6 19.Dh6+- ]
18.Fd4 Tg8 19.Th3 b5 [19...exf5? 20.Cd5 Dd8 21.Dg5+- ]
20.Dg5 Tae8?? [>=20...e5 21.Cd5 Dxc2-/+ ]
21.Tb3+- Ff8 [21...Da5 last chance of counter play. 22.Cd5!! Leurre: d5 22...De1+ 23.Ff1 Dxe4 (23...Cxd5?? is refuted by a mate in 2 24.Txh7+ Rxh7 25.Dh5# ) 24.Fxf6 Dxf5 (24...gxf6?? 25.Txh7+ Rxh7 26.Th3+ Dh4 27.Txh4# ) 25.Dxf5 exf5 26.Fxe7 h6 27.Fxd6 Te1+- ]
22.Cd5!! Mate attack
22...Dc5 [22...exd5 23.Txh7+ Mate attack; 22...Cxd5 23.Txh7+ Mate attack; 22...-- 23.Cxf6 ]
23.Fxc5 exd5 24.Fd4 [24.Fd4 Te5 25.Th4+- ] 1-0
Anyway, this was a VERY poisoned pawn, in this Sicilian variation !! I'm happy to see some good tactics from Hakkapeliitaa.
Maybe the position is a bit tricky for engines but is interesting for further matches !!
