I would guess that Curtains' range includes TT-AA, AK. It might include AQ and 99 depending on the initial raiser.
Pokerstove v. the tight range says:

equity (%) win (%) / tie (%)

Hand 1: 43.2287 % [ 00.42 00.01 ] { JsJc }
Hand 2: 56.7713 % [ 00.55 00.01 ] { AA-TT, AKs, AKo }

If we can widen his range to include 99 and AQ, it's a clear call. As J-lo noted, we're getting an overlay of 1170:745, which means we should probably call anyways. Although, I can still see a possible fold there based on uncertainty about my read of Curtains and the fact that the initial raiser is still in the hand.
