Crazyhouse Computer Championships 2016

[Vinvin]

I have found sacrifices and body contact checking to be very useful. Note at move 17 SF thought it was winning , but game was over by move 26.

On Github we discussed about "unblockable checks" ( = contact + knight + only useless pieces to put on the line) : https://github.com/ddugovic/Stockfish/issues/95

Correct - currently there are no plans to make it a variant. Initially , because of the slowdown ~ 10%. But on my last build , the normal variant was benching the same. If there is a desire to combined them into 1 app , I have no objection with that.

I guess SF sse in that link does no play zh is that right?

BTW could you inform the authors of Sf zh that the zh championships will now be held this coming 2016-12-02. Perhaps they have some build to participate. Thanks.

My best game so far - level 1600, SFv see about 1000 nodes per move at this level. First time I ever went with b3 as my first move in CH. The game changer was my timely Q sac by letting her go and instead playing 25. exd6+. The weakened SFv had not yet seen the danger of 26. dxc7+

I will take that.
Engine update is allowed, so bug fixes and further improvement can still be entered.
