Hey Andrew, This is a technique I learnt from Scott Farrell. I use: if (last_move was capture && current_move is a capture && the captures are on the same square && the value difference of the two captured pieces is within 1 pawn && the capture brings us back to within at least MARGIN to the root material balance) then extend by 1 full ply. I think margin is 1 pawn at the moment, though I am at work and cannot remember exactly. I can't say I have extensively tested whether this approach is better than no recap extension at all. But I do know that it is better for bodo than having the recap extension as how I described before. To anyone else, please feel free to share any of your special techniques of constraining the recap extension! ;) Joel
