I'll participate with my new Isa , If I don't miss its at 20h00 instead of 21h00 :?
Yes, since a few months the tourney starts at 20:00 instead of 21:00, this is more convenient for the tourney manager.

Henk is very eager to play the new Isa. :wink:

Re: interesting position

From a recent online game: 5rk1/5pp1/pQ3n1p/2P5/2pP4/P1Nb2P1/1B3PKP/4r3 w - - Black's King is in some distress, but on the other hand, White has a couple of passers. It is even, but White has to play the somewhat unintuitive g4! here. Stockfish and Houdini are very fast on this but other engines ma...

Re: Minic raw speed

Minic seems to do 1.9 mnps at the start position with a single thread on a 4.4 GHz. cpu and that is somewhat slow. It could be false sharing, but with lazy-smp (besides the TT) you hardly share anything. What I don't get is that TCEC lets engines run on 176 threads on 88 core hardware, hyperthreadin...

Re: Minic raw speed

Perft 6 of start pos in 4.7sec, so move gen + copy make at 25Mnps .... probably not the issue Pure eval (during texel tuning) at 2.7Mnps, this is probably a bit slow maybe Standard search on same hardware is at 1.9Mnps A perft of 25 mnps on the start position without bulk counting seems about right...

Re: On-line engine blitz tourney December

Funny thing is that atomNightmare (an old version of Nightmare running single core on a J3455) ended well above it's 30 times faster big brother. It shows that in a Swiss tournament with very little rounds everything is possible. Some engines were missing (like all HGM's engines to name a few), some...

Re: Null move test

In Nightmare the rule to allow nullmove is: at least one king-move plus a move with another piece (not a pawn) to a square that is not attacked by the opponent. Nightmare does not solve Jons position either and goes for a repetition draw, it solves the position of John (Kf4) after 54 seconds at 33 p...
