two most interessting positions

Its a bit offtopic because it was a unimportend online match but so interessting that i want to share.

The following two positions happen to me.
To be honest... I just dont fully understand the result of the analyze.

i felt really strong here and doubled. i was sure it is correct to double.

there is close to no roll which could make a problem and lots of rolls for a perfect go.

44, 55, 51,61 are clear winners. what ever my thoughts are wrong doubeling is considered as error.

chance to win the game is 71.48%. i really dont understand that doubeling here is a error

but if you think such unclear situations are exeption here we go:

the same match just 2 games later i am in a situation where i somehow dont feel so extreme strong.

analize say that my chance to win is 71.03 %. the chance to win the game is lesser then the first example.

i didnt doubled and guess what !?? its a blunder not to double !!! isnt it crazy ?

the diffence is that in this case i have a 22 % chance for a gammon and nearly no chance for gammon in the first case. but come on, a blunder !

your oppinion is very welcome. share your thoughts about it.
