What's obvious and what's not to a human is difficult to figure out. And since you are losing, there is probably no best "swindle" move.. But i was wondering if a test suite of succuessful "Swindles" from GM games could be collected to test swindle mode..Taht's assuming if anyone is willing to take the time and effort to improve swindle mode.. It would make the chess engine more human like i suppose, but wouldn't help strenght wise much against very strong opponents..
