You are right, I made the test with 2Min/move(I was using time=10000sec/move,
without tablebases from Junior6 CD).
It seems that with Infinite analyses Junior also do small jumpers
(see my post to Chessfun).
I didn't still understand because Junior changes Qh8+ for Qe5+, but I
already saw that a lot of times, mainly when you change for the Infinite
analyses mode (also with others programs that have Inf. Analysis mode).
