Game Theory: Unusual Question #3 and #4

[Bozeman]

"The value-raise and bluff-raise criteria for B must be the same as in #3 because A has no additional options when B raises. So, I don't see how there can be any difference there."

This is false: value-raise criterion depend on A's option because now B will raise more hands because it preempts A's raise. And the bluff-raise criterion is set by the value-raise criterion.

I am willing to bet on the correctness of the proposed optimal strategies.

Especially in the absence of anything close to a viable alternative. This isn't rocket science,
