Ajax Chess 3.0

It's slowly getting stronger . Still lacking pawn evaluation though.

Changes:
- 604.5/1000 or ~70 ELO better than previous version
- Killer moves
- Tuned PSQ tables/mobility
- Better king eval in endgame (won't stay on back row)
- Show '#' for checkmate
- Improved UI (new game, switch black/white, choose time/move)
- Fixed crashes from using invalid hash moves
- Other small bug fixes
- Speed optimizations

Thanks, Gary. What elo do you estimate for it?

and could it be made as .exe?

I'm not honestly sure what ELO. Probably plays about 2000 tactically, and 1200 positionally . That's on Chrome, where it searches about 150k NPS.

I can't do an EXE version easily unfortunately, as there aren't good, fast javascript hosts easily available.

How do you stop abuse of ajax? I have an ajax application that responds to people typing in words in a textbox, and the ajax app responds to their key presses by calling the php script each time. How do I stop a person constantly typing stuff and causing the server difficulty in trying to handle all the requests?

You could possibly make it an EXE with the help of NodeJS, although I have trouble running Node on Windows so it would be kinda useless anyway.
