If using InBetween in this way really does weaken crafty so much, there can only be 2 reasons: 1. InBetween uses too much CPU, or is too slow relaying commands, or 2. the resigning has this effect. For (1) Maybe Odd Gunnar could comment about InBetween? For (2) I doubt though that resigning would have this effect when Crafty plays itself. Maybe more testing is indicated? I suppose there could be a 3rd option... maybe other settings are also changed by Crafty when it receives "computer"? Cheers, Tim.
