In this game StockFish clearly outplayed Fruit, but...

1/ StockFish's score stalled at +4.36 from move 67 to 80. I believe the position was actually a draw, and don't see any forced way for white to make any progress, which is what happenned for that period (67->80). However, luckily for StockFish, Fruit blundered at move 80, and StockFish found the winning continuation.

2/ In a KBBK ending, I would assume SF (using score tables to push King in a corner) would easily find the mate. In fact it did, showing Mate+X score for most of the remaining 50 moves... SF was playing immediately, seeing that it returned a Mate score. It had 30 seconds per move of increment, and shoul've been trying to decrease the X in Mate+X at every move, rather than being happy with any Mate+X move. Of course, from that bug resulted a 50 move draw, where SF had over 27 min on the clock (30 sec inc).

NB: I am using Wine+Arena, so the first thing to see is whether this is reproducable, or whether it is a time bug in my Wine+Arena setup (both Wine and Arena are extremely lame and buggy).

Re: Stock drew in KBBK !?

It would be interesting to see what other programs think of the game positions from move 67 to 80. I wonder if Houdini + Gaviota EGTB understands black's drawing strategy.
It's probably a very difficult draw for computers to understand.

[d]3k4/8/Pb3p2/1P3B2/2K5/5b2/7B/8 b - - 24 80

Here, Fruit played Ke7??

In an AMD 2.4 Ghz (2x) it takes ~100 seconds to Gaviota (with its own TBs) to realize Ke7 is a blunder. Forcing Ke7, the evaluation starts increasing until it sees a win, so the fail low with Ke7 real. If Ke7 is not played, the evaluation gets stuck, so it may not see a winning path after that.

Yes, but I can't blame him, as you pointed out it's a tricky situation to evaluate for other engines too.

To its credit, Stockfish seems almost immediately that Ke7 is a blunder, and SF has no EGTB.

If this is so, why do you use them? :?

Both Fruit and Stockfish are available as native Linux versons, I think, and you could run them under a natively running XBoard..

I have to check the other games in this gauntlet, but I think it had trouble winning a KRK endgame.

I should not say it had trouble winning certain endgames, besides the KBNK listed above. It just played some endgames a little different than what I have seen before. At least that is my subjective opinion.

StockFish 2.0 could easily win KBBK or KBNK, by using score tables to drive the King in a corner (for KBBK) and in a corner of the colour of the B in a KBNK.

There might have been a regression there in SF 2.1

This is a general comment not necessarily related to SF: When problems like this happen, it may be because of something else. The knowledge may be there but the decision when to stop thinking, how to save checkmates in a HT, or how to back-propagate the check mate info could be altered. Particularly when problems with more than one checkmate is observed.

This is the reason why sometimes it is good to test without adjudication: to catch bugs.

It is also the reason why I never resign in OTB computer tournaments, It payed off again in Leiden (ICT11) last Sunday, where Red Queen could not finish a totally won game, because it insisted playing for the other side from a certain move on, and persisted in doing that even after two restarts. I agreed to the draw that was offered, although I could also have claimed the full point.
