FruitFly finds #1 easily:

Score : +2.56

FruitFly needs a bit more depth for #2, but still solves it:

1... Nd7 2. Kd2 Kd6 3. Kd1 Kc6 4. Kc1 Kb5 5. Nc5 Nxc5 6. dxc5 Kc6 7. Kd2 Kxc5

FruitFly finds this rather easily

Score : -3.20
Depth : 7/1
Time : 00:00:00
Nodes : 49030
N/sec : 55505
1... Rxe4 2. f5 Rxe2 3. Nxe2 Re8 4. Nf4 Ne3 5. Kg1 Nxc2 6. fxg6

Note though how all problems were solved in less than a second.
