the math:

pot odds: 340000 : 460000 = 1 : 1,35

10% bluff
50% underpair
40% AA,KK (correct?)

10% against bluff you win 802500 in 64%
you loose 340000 in 36% - EV: +39120
40% against underpair you win 802500 in 45%
you loose 340000 in 55% - EV: +69650
50% against AA,KK you win 802500 in 18%
you loose 340000 in 82% - EV: -67175

overall EV +41595

even this scenario is +ev if his range is wider AQ,AJ or something like that this gets more +EV

only if you give him 75%+ for having AA,KK this should be a fold.
