Retire the misdesigned StepAttacks[] array. 

StepAttacks[] is misdesigned, the color dependance is specific to pawns, and trying to generalise to king and knights, proves neither useful nor convinient in practice. 

So this patch reformats the code with the following changes: 
- Use PieceType instead of Piece in attacks_() functions 
- Use PseudoAttacks for KING and KNIGHT 
- Rename StepAttacks[] into PawnAttacks[] 

Original patch and idea from Alain Savard. 
No functional change.

Copy killers in the movepicker 
ss->killers can change while the movepicker is active. 
The reason ss->killers changes is related to the singular 
extension search in the moves loop that calls search<> 
recursively with ss instead of ss+1, 
effectively using the same stack entry for caller and callee. 
By making a copy of the killers, the movepicker does the right thing nevertheless. 

Tested as a bug fix

Chess engines: asmFish 2017-04-26 and PedantFish 2017.04.26

asmFish 2017-04-26 - download

 asmFish: trim off the cruft in official stockfish and make a lean and mean chess engine. It is 99.9% official stockfish as there are some inconsequential functional differences in official that were deemed too silly to put into asmFish.

pedantFish: match bench signature of official stockfish to catch search/eval bugs more easily.

The Tarrasch Chess GUI - new version: Tarrasch 3.02a,

Tarrasch is an extremely easy to use free chess program for Windows.

Tarrasch comes with free chess engines, so you get everything you need to enjoy computer chess with one simple free download.

Tarrasch is designed to to make it as easy as possible to perform some basic chess activities; Play a game against a chess engine, with either color, from any position, with a time handicap if desired.
Setup an arbitrary position and get the engine to analyse that position. View and play through the analysis provided by the engine.
Create and edit .pgn files (standard chess documents). Enter variations easily (just make moves anywhere). Enter and edit comments easily (just click anywhere and start typing). Promote and demote variations and even comments (so comments can change to moves and vice-versa – great for picking text off a website)..


News - Tarrasch 3.02
This version is a bug fix release, correcting all problems discovered in the first quarter of 2017. Sadly this includes some significant problems, and upgrading to this version is strongly recommended. Change log;

Annoying problems with editing games with many variations and comments (so that the edit window needs to scroll) fixed. The edit cursor no longer jumps to bottom line, and scroll position is preserved if you switch tabs.
A side effect of the fix above is that text editing (for comments) is faster than ever, faster than previous V3 versions and much faster than V2.
Introduce Tarraschbase - Kingbase lite 2016-03 plus more recent games from Twic. This is hopefully a temporary measure until Kingbase is updated again.
Screen adjustment for improved games dialog behaviour on commodity 720p laptops.
Kibitz box is dynamically scaled to show all four lines - not always 99 pixels high.
Deleting games in games dialogs behaves better.
Stalemate and Checkmate positions no longer sent to engine for analysis.
Bug fixed: (Bug was; Cannot save recalculated ECOs to file.)
Bug fixed: (Bug was; Modify game -> make new tab -> go back to game -> undo changes game still shows as modified even though undo stack correctly shown as empty).
Inappropriate sharing of pgn games dialog help screen with clipboard and session games dialogs corrected.

Long overdue update from Komodo V3 to Komodo V8 (apologies for not noticing that the Komodo free version has changed dramatically).

Use int instead of Value for history related stats. 
history related scores are not related to evaluation based scores. 
For example, can easily exceed the range -VALUE_INFINITE,VALUE_INFINITE. 
As such the current type is confusing, and a plain int is a better match.
