hand 1:
while against his donk betting range (i'll assume its the same as his pf 3betting range)your hand may be an equity favourite:

Board: 4h Kc 9d
Dead:

equity win tie pots won pots tied
Hand 0: 45.473% 44.36% 01.11% 19763 495.00 { QdQs }
Hand 1: 54.527% 53.42% 01.11% 23797 495.00 { 99+, AQs+, AQo+ }


when you shove you CALL the bet against that range, and offer him $17 more dollars for the part of his range which has you crushed and is never folding (AA,AK,KK,99). (not counting card combos this is half of his cbetting range)

Board: 4h Kc 9d
Dead:

equity win tie pots won pots tied
Hand 0: 09.188% 09.19% 00.00% 2183 0.00 { QdQs }
Hand 1: 90.812% 90.81% 00.00% 21577 0.00 { KK+, 99, AKs, AKo

given you have position and villain is unlikely to keep owning himself with less than KQ, i like to call on the flop, keeping his range wide enough, and re-evaluating on the turn.

hand 2:
preflop is a no-brainer call. i probably dont bet the flop given if villain is not FOS then we only fold AK, and the rest kills us. certainly not calling the shove.

Board: 3c 4d 2h
Dead:

equity win tie pots won pots tied
Hand 0: 38.763% 37.79% 00.98% 29926 774.00 { 6h6s }
Hand 1: 61.237% 60.26% 00.98% 47726 774.00 { 22+, AKs, AKo }

that range is a bit lenient because he's far less likely to check shove AK than any of the paired hands (all of which have you beat, except 55)
